Part I: The Imperative Shift Towards Eco-conscious Living

Our planet hangs in the delicate balance of our actions. We are at the helm of an existential crisis – climate change, bolstered by greenhouse gas emissions where the construction sector notoriously plays a prominent role. To counter this, our studio has made it its mission to create buildings that harmonise with nature rather than wage a war against it.

To paraphrase a renowned philosopher, we did not inherit the earth from our ancestors; we borrow it from our children. With this in mind, our role as architects goes beyond mere design. It’s our responsibility to pave the way for a sustainable future, creating eco, Passivhaus, and zero-carbon homes that marry form, function, and the ethos of conservation.

Throughout the UK and indeed globally, there has been an appreciable shift towards eco-conscious design. More and more property developers are acknowledging the necessity for sustainable design, implementing systems that champion energy conservation, thereby significantly contributing to reducing carbon emissions. Our role as architects is instrumental in this movement, steering the tide towards the creation and retrofit of homes that strive to achieve this global objective.

Part II: The Promise of Eco Houses, Passivhaus, and Zero Carbon Homes

Imagine a world where homes and lifestyles align in perfect symmetry with nature. On one hand, we’d make significant investments in renewable energy, tapping into the bounty of the sun, wind, and water. On the other hand, we’d create dwellings that leverage these energy sources and preserve them.

Passivhaus houses and zero-carbon homes represent the very embodiment of this vision. They provide a roadmap for future sustainable developments, adding immense value, bolstering environmental credentials, and cultivating healthier, happier living spaces. So how does one design and build such homes without exorbitantly overshooting the budget?

Part III: Breaking Down The Science of Sustainable Design

As we wade deeper into the age of sustainability, it’s clear that our global resources are fast depleting. But, as the adage goes, when the winds of change blow, some build walls while others build windmills. Just as the automotive industry has successfully ventured into electric cars, the construction industry too has started to turn the tide. Today, we stand at the forefront of creating zero-carbon homes – once considered a far-fetched dream but now a tangible reality.

Our architectural studio specialises in designing eco houses and retrofitting existing homes, placing energy conservation at the epicentre of our design process. We’ve successfully designed and built numerous low energy homes across the UK, in conjunction with government incentives that encourage households to insulate lofts or fill in cavity walls. Yet, the path to sustainable living is a long one, and there is much more to be done.

Part IV: Unravelling the Magic of Passivhaus Homes

The Passivhaus design standard, a beacon of sustainable housing, focuses on maintaining comfortable temperatures with minimal energy use. Its underlying philosophy is to construct homes that harness passive energy sources, such as sunlight and heat from human activity and appliances. This drastically reduces the need for space heating and cooling, resulting in comfortable, well-lit homes that leave a lighter ecological footprint.

Part V: The Blueprint of Zero Carbon Homes

Zero carbon homes are a leap forward into the realm of renewable energy. These homes aim to generate as much renewable energy as they consume, effectively nullifying their carbon emissions. But this is not without its challenges – not every location is suitable for renewable energy generation, and high-density urban areas pose their unique set of constraints. Here’s where the creativity of architectural design comes into play.

Harmony in Design: The Passivhaus Standard

Embarking on our journey into the eco-home terrain, let’s first explore the innovative Passivhaus design. This holistic approach to construction aims to build homes that maintain optimal temperatures with minimal energy input, largely leveraging natural resources like sunlight and heat from appliances and human activities.

The Passivhaus ethos hinges on factors such as the home’s dimensions, form, orientation, thermal retention capacity, airtightness, and efficient ventilation and heat-recovery systems. The ultimate aim? A drastic reduction in the dwelling’s yearly carbon footprint.

A crucial part of the Passivhaus equation is ensuring that space heating doesn’t exceed 15 kWh/m². This constraint demands thoughtful consideration of the home’s climatic setting. For instance, in the UK, meeting the Passivhaus standard entails incorporating high-quality insulation, installing high-performance windows with insulated frames, fostering airtightness, creating ‘thermal bridge free’ construction, integrating a highly efficient heat recovery system, and a meticulous design process underpinned by the Passive House Planning Package (PHPP).

Embracing the Sun: Passive Solar Design for Sustainable Homes

Next is the focus on the sun – nature’s most abundant source of energy. Passive solar design allows us to harness the sun’s heat and light directly, reducing the energy requirements of our homes.

Critical to this technique is the orientation of the building. In the northern hemisphere, optimally, the buildings should face south, and windows should predominantly adorn the south side, to maximise solar gain. Existing structures might not permit change in orientation, but retrofitting initiatives can include superior, thermally-efficient triple glazing on the southern side.

But here’s the kicker: while we soak up the sun’s gifts, it’s essential to avoid overheating, especially during summers. Features like extended eaves and strategically positioned blinds can curb high-angle sun penetration without hampering natural light infiltration.

Thermal Alchemy: U Values and Eco-Friendly House Design

Pivoting to the core of the building, we delve into the materials that give it life. The sustainability of a home is deeply rooted in the carbon cost of its construction materials. Options such as sustainably sourced timber, cob, and straw present greener alternatives to traditional, carbon-intensive materials.

A crucial concept that helps us comprehend the thermal efficiency of these materials is the U value, which quantifies the rate of heat escape from a building. A lower U value implies slower heat dissipation, which is a Passivhaus mandate, setting limits on.

Towards the conclusion of this journey into the intricacies of eco-home building, it’s imperative that we answer some of the frequently asked questions you might have concerning the venture. We hope that these answers will illuminate your path as you progress towards constructing a sustainable, visually appealing, and low energy-demanding home.

Can I Build a House on my Land in London?

Building a home on your own land is a dream many people share. The ability to customise every aspect of your living space and create a place that perfectly suits your needs and desires is undeniably appealing. However, before you can embark on this exciting journey, there is one crucial hurdle to overcome: obtaining planning permission. Without it, your dreams will remain just that – dreams.

In this comprehensive guide, we will explore the intricacies of obtaining planning permission in the UK from the perspective of an experienced architect with 20 years of experience in a small, contemporary design-led architecture studio. With a focus on low energy and low embodied carbon designs, we understand the importance of sustainable and environmentally friendly solutions in today’s world.

Whether you are considering building on backland sites, Green Belt land, agricultural land, or brownfield plots, we will delve into the specific challenges and considerations associated with each type of development. By providing valuable insights and practical advice, we aim to empower you with the knowledge needed to navigate the planning process successfully.

Section 1: Understanding Planning Permission

Before delving into the intricacies of specific types of developments, it is crucial to understand the concept of planning permission itself. Planning permission is essentially the agreement granted by your local authority to allow you to develop land for a building project or a change of use. Local authorities closely monitor all developments to ensure they align with their standards and vision for the area.

The National Planning Policy Framework (NPPF) provides guidelines to all local authorities, which they adapt and customise based on their specific circumstances. In most cases, obtaining planning permission is a requirement when creating a new home, whether it involves building from scratch, extending an existing building, or subdividing it to create additional living spaces.

While some home improvements may not require planning permission, it is essential to understand the procedure to maximise the chances of success. Typically, full planning permission is necessary for new dwellings, including self-contained annexes or entire blocks of flats.

Section 2: Building on Backlands

Backland development refers to building on land that is not visible from public areas, such as roads, and is usually located in already developed areas. This type of development, also known as urban infilling, can include building on a garden plot or a piece of back garden land. Backland development can be carried out by individual homeowners looking to capitalise on their land or by groups of homeowners collaborating on a development.

While backland development has faced opposition and criticism, it can be a viable solution for increasing housing stock in urban areas. If you are considering developing your back garden land or building on your property grounds, several crucial questions need to be addressed:

  1. Is road access available? Easy access to the public highway is ideal for any building plot. If direct access is not possible, having a quick path under your control can still be acceptable.
  2. Will the new building impact neighbours negatively? It is essential to consider factors such as blocking light or affecting neighbour’s’ privacy. Maintaining good relations with your neighbours and accommodating their concerns can significantly impact the success of your planning application.
  3. Does your development include off-road parking? Unless your property is located in a town centre or near a train station, local authorities will likely expect you to provide dedicated off-street parking spaces.
  4. What is the ecological impact of your development? Trees and local ecology must be considered when seeking planning permission for backland development. Conducting an ecological survey to assess the potential impact is often necessary. In some cases, compensatory measures, such as planting new trees, can help offset any negative effects on the natural environment.

To ensure the success of your backland development, careful consideration of local planning policies, architectural design, and collaboration with professionals experienced in this type of development is crucial. By addressing the concerns of both the planning department and the local community, you can increase the likelihood of obtaining planning permission without significant obstacles.

UK Green Belt construction, despite concerns for nature conservation, is possible under certain exceptions. Knowledge of these is vital for aspiring homeowners or developers planning projects in these areas.

Section 3: Building on Green Belt Land

Building on Green Belt land remains a contentious topic in the UK. While preserving the countryside and protecting nature and wildlife are valid concerns, certain exceptions exist that allow for development on Green Belt land. Understanding these exceptions is crucial if you wish to build your dream home or develop a housing project in a Green Belt area.

Green Belts are designated zones surrounding major cities, towns, and urban settlements with the primary purpose of preventing urban sprawl. However, not all Green Belt areas are idyllic open spaces; some include already built-up areas. It is important to distinguish between Green Belt land and other protected areas, such as Areas of Special Scientific Interest (SSIs), Areas of Outstanding Natural Beauty (AONBs), ancient woodlands, listed buildings, and flood risk zones.

Certain circumstances may lead to a successful planning application for Green Belt land:

  1. Previously developed land: Some Green Belt land has already been developed. If you can demonstrate that your new buildings will have no more impact on the Green Belt than what was previously there, you have a good chance of obtaining planning permission. Agricultural buildings are not considered previously developed land, although there is a permitted development right to convert barns and stables into homes.
  2. Infill developments: Building in gaps between existing properties in villages can be successful if it has minimal impact on the surrounding area. Such developments fill in spaces without significantly altering the character or landscape of the village.
  3. Affordable housing provision: Meeting the need for affordable housing in rural areas can increase the chances of obtaining planning permission. If your plans align with the local housing plan and address the shortage of affordable housing, your application may be successful.
  4. Exceptional properties: Under the National Planning Policy Framework (NPPF), “Paragraph 80 houses” may be granted planning permission if they enhance the appearance of the local area and compensate for any damage to the Green Belt through exceptional design and sustainability features. If you aspire to build a remarkable, environmentally sound home in a rural setting, this approach may be suitable.

Navigating the complexities of building on Green Belt land requires careful consideration of local policies, understanding the unique circumstances of the land in question, and developing designs that respect the surrounding environment. Consulting with architects experienced in Green Belt developments can help you craft plans that align with local requirements, increasing your chances of obtaining planning permission.

With UK farming in decline, unused agricultural land is becoming available for residential development.
With UK farming in decline, unused agricultural land is becoming available for residential development.

Section 4: Building on Agricultural Land

While many people perceive agricultural land and Green Belt land as similar, the distinction is essential. Agricultural land serves the purpose of food production and other agricultural activities. However, with farming on the decline in the UK, some agricultural land is no longer operational, opening up opportunities for residential development.

Building on agricultural land is not a straightforward process, and it is crucial to understand the challenges involved. The cost of agricultural land without planning permission is significantly lower than that of comparable plots with planning permission. However, assuming that purchasing agricultural land, obtaining planning permission, and making a fortune is a straightforward path is a high-risk gamble.

To increase your chances of success when building on agricultural land, consider the following steps:

  1. Research local housing policies: Understanding the local council’s policies on housing, especially those addressing the housing shortage, can provide insights into sites where development is likely to be approved. If your land is on the edge of a town or within a strategic development area, it may have a higher chance of obtaining planning permission.
  2. Participate in the call for sites: Local councils periodically review their local plans and call for sites to be submitted. This process stimulates landowners and developers to propose potential development sites, including agricultural land. Preparing your land in advance by working with an architect specialising in agricultural property development can ensure you are ready to submit your site during the call for sites process.
  3. Assessment and local plan review: The council will assess the submitted sites through several stages to determine the most suitable options that align with environmental, economic, and social considerations. The selected sites will be included in a draft document as part of the local plan review, and public input will be sought to determine the best options.

Building on agricultural land requires careful consideration of local planning policies, economic viability, and the long-term sustainability of the proposed development. Engaging with planning consultants who specialise in agricultural land development can provide valuable guidance and support throughout the process.

Developing brownfield land, which includes more than just abandoned factories or wastelands, is increasingly viewed as a solution to the housing crisis.
Developing brownfield land, which includes more than just abandoned factories or wastelands, is increasingly viewed as a solution to the housing crisis.

Section 5: Building on Brownfield Land

Building on brownfield land is gaining attention as a potential solution to the housing crisis. Brownfield land refers to previously developed land, encompassing a wide range of sites beyond abandoned factories or wastelands. However, it is important to note that brownfield land does not automatically mean unused or environmentally degraded areas. Many previously developed sites can still possess natural value and require consideration of ecological impact and heritage preservation.

Advantages of building on brownfield land include:

  1. Planning policy considerations: Planning applications for brownfield sites can often be more straightforward due to the recognition that previously developed land is suitable for development. However, this does not eliminate the need to address other factors such as access, parking, neighbour’s’ concerns, and ecological impact.
  2. Availability of land: The National Housing Federation’s comprehensive map provides a valuable resource for identifying brownfield sites across the UK. Investing in property development on brownfield land can offer opportunities to transform underutilized spaces into vibrant communities.

Building on brownfield land requires careful assessment of the site’s suitability for residential use, including access, infrastructure, ecological impact, and local planning policies. Collaborating with architects who understand the intricacies of brownfield development can help you navigate the planning process effectively.

Do I Need an Architect?

Do I need an architect? 

Investing in a building project is not a decision to be taken lightly. It involves a substantial commitment of finances and personal aspirations. When embarking on such a venture, it becomes very important to ensure that every aspect is meticulously handled with expertise and precision. While it may be tempting to solely rely on the skills of a builder and opt for a straightforward approach, it is essential to recognise that the true potential of a project can only be unlocked with the involvement of an architect. In this blog post, I aim to shed light on the pitfalls of not involving an architect and emphasise the considerable value that an architect can provide.

What is the Role of an Architect?

Architects are not mere draftsmen; they are professionals who dedicate years to honing their craft. Through a combination of rigorous training and practical experience, architects acquire a unique skill set that encompasses both creativity and technical acumen. At RISE Design Studio, we approach every project as an opportunity to solve problems and create tangible buildings that surpass client expectations.

What about Insurance and Accountability?

One of the fundamental reasons to hire an architect is the assurance it brings. In the United Kingdom, all architects must be registered with the Architects Registration Board (ARB) and carry adequate professional insurance. This not only ensures that architects adhere to stringent industry standards but also provides clients with recourse in the event of any unforeseen issues. At RISE Design Studio, we take our commitment to excellence a step further by being an RIBA Chartered practice, fully aligned with the Royal Institute of British Architects’ Code of Practice. This level of accountability further underscores the importance of involving an architect in your project.

Architects possess a unique ability to transform abstract ideas and aspirations into tangible structures. By employing a holistic approach that considers aesthetics, functionality, and sustainability, architects are capable of breathing life into your vision. At our design-led architecture studio, we have an unwavering focus on low energy and low embodied carbon designs. This means that not only will your project be aesthetically appealing, but it will also be environmentally conscious and energy-efficient.

How do I Mitigate Pitfalls and Maximise Potential?

The decision to forego an architect can lead to several pitfalls that may impact the success of your project. Without an architect’s guidance, it becomes challenging to navigate complex building regulations and obtain necessary permits. This can result in costly delays, fines, or even legal complications. Additionally, the lack of a comprehensive design strategy can lead to inefficient use of space, inadequate lighting, poor ventilation, and subpar energy performance. These issues not only diminish the comfort and functionality of the building but also have long-term implications on operational costs and environmental impact and resale value.

Collaboration and the Architect-Client Relationship:

Working with an architect fosters a collaborative relationship between the client and the design professional. Architects invest time in understanding your unique requirements, aspirations, and constraints. By forging a strong partnership, architects can translate your desires into practical design solutions. This close collaboration ensures that the final outcome aligns seamlessly with your vision while incorporating innovative design elements that you may not have considered otherwise. Furthermore, architects possess the skills to communicate complex design concepts effectively, allowing you to visualise and actively participate in the evolution of your project.

Sustainability and a Future-Forward Approach:

In an era where environmental consciousness and sustainability are of utmost importance, architects play a pivotal role in creating buildings with low embodied carbon and energy-efficient designs. At RISE Design Studio, we are committed to reducing the environmental impact of our projects through careful material selection, passive design strategies, and the integration of renewable energy systems.

Initiating the Conversation:

Once you have identified potential architects who align with your aspirations, it is time to initiate a conversation. This initial interaction is pivotal in assessing the architect’s suitability for your project. Consider whether you genuinely want to work with them. Do they actively listen to your ideas and concerns? Are they invested in understanding your unique requirements? A good architect will ask thoughtful questions, provide reassurance, and demonstrate their ability to comprehend and address your worries. It is crucial that they explain their work process clearly, avoiding unnecessary jargon and ensuring you have a comprehensive understanding of what to expect. If you anticipate working with other members of their team, it is worth exploring the possibility of connecting with them as well.

Building a Strong Rapport:

Given the collaborative nature of architectural projects, building a strong rapport with your architect is essential. Throughout the process, you will be working closely together, sharing ideas, and making decisions that shape the final outcome. Consequently, it is important to enjoy the company of your architect and promote a good working relationship. Trust and open communication are the cornerstones of a successful collaboration. Listen to your instincts and assess whether you feel comfortable, understood, and inspired by the architect’s approach. Ultimately, your heart, rather than your head, will guide you towards the architect who feels like the perfect fit.

Why use a London Architecture Practice?

London’s vibrant and diverse built environment presents unique challenges for buying a property, obtaining planning permission, and building your dream home. In this article, we will explore the numerous benefits of engaging with London architecture practices and highlight the significance of local experience when selecting architects. As an architect with over 20 years of experience in a small contemporary design-led architecture studio, our focus on low energy and low embodied carbon designs enables us to provide valuable insights into the pitfalls of not utilising an architect’s expertise. Let’s delve into the reasons why partnering with a London architecture practice is vital for a successful outcome.

Understanding the London Landscape:

A London architecture firm possesses a deep understanding of the intricacies and nuances of the city’s architectural landscape. By comprehending the specific location of a property, an architect can distill the various policies, opportunities, and constraints of each borough, achieving the desired size and design of extensions or refurbishment. The local architect’s expertise maximises the value of every square meter, optimising the potential of your project.

Navigating Planning Challenges:

Obtaining planning consent and successfully building in London’s 32 boroughs demand the right experience and knowledge. By engaging a local architecture firm in London, you benefit from their extensive experience in obtaining planning consent across various boroughs. This knowledge proves invaluable at every stage of the process, enabling effective decision-making. A local architect can provide insights on scaling, massing, external materials, conservation area limitations, Article 4 Directions, basement policies, and listed building issues specific to each borough. Understanding the intricacies of each borough’s planning process ensures a smoother journey towards obtaining the necessary approvals.

The Value of Local Research:

During the early stages of a project, your architect conducts in-depth research on the specific site planning history and immediate context. This research helps determine what is permissible and informs the subsequent design process. By tapping into their local knowledge and experience, architects can navigate potential hurdles and create designs that align with the local environment and regulations. Local research further ensures that your project is sensitively integrated into the existing fabric of the city.

The Hunt for Local Talent:

Identifying leading London architecture firms whose aspirations align with your own can be facilitated through regional design awards. These accolades highlight firms that have excelled in delivering outstanding architectural solutions. Additionally, keep an eye out for local signboards displayed on properties similar to yours, as they often indicate the involvement of architects with relevant experience and expertise.

The Power of Collaboration:

While architects play a crucial role as the lead consultant, successful projects require a team of specialists with diverse design and construction skills. A reputable London architecture practice will have a network of local consultants, fabricators, sub-contractors and craftspeople who possess the necessary experience and expertise to deliver high-quality projects within time and budget constraints. Collaborating with these professionals ensures seamless coordination and a holistic approach to design and construction.

Understanding Key Consultants:

In addition to the architect, several key consultants contribute to the success of a project. These include the structural engineer, quantity surveyor (cost consultant), and approved inspector.

  • Structural Engineer: The structural engineer ensures the proposed design can withstand various loads and provides crucial services such as site appraisal, structural design, and on-site inspections. They play a vital role in ensuring the safety and stability of the structure.
  • Quantity Surveyor (Cost Consultant): The quantity surveyor provides estimates and advice regarding the cost of construction works. They help develop the project budget, prepare cost plans, assess tender returns, and compile the final account.
  • Party Wall Surveyor: The role of a Party Wall Surveyor in architecture is to provide expertise and guidance in matters related to party wall disputes and the Party Wall Act. When undertaking construction or renovation projects that involve shared walls or structures with neighboring properties, a Party Wall Surveyor acts as an impartial third party to ensure that all parties’ rights and responsibilities are protected. They assess the potential impact of the proposed work on adjoining properties, help draft party wall agreements, resolve disputes, and ensure compliance with legal requirements. The Party Wall Surveyor plays a vital role in facilitating communication and resolving conflicts between property owners, safeguarding the interests of all parties involved in the construction process.
  • Approved Inspector: An approved inspector ensures compliance with building regulations. Their expertise includes assessing initial design proposals, conducting site visits during construction, and issuing the final certificate.

RIBA Plan of Work 2020: A Comprehensive Guide

Architects like most professions welcome industry led guidelines and approaches to inform and improve their work both for their clients, collaborators, and their own progression.

The RIBA Plan of Work 2020 is a guidance document set out by the Royal Institute of British Architects (RIBA) and is seen as the definitive design and process management tool for the UK construction industry.

First established in 1963 to provide a framework for architects to use on client projects to bring greater clarity to each stage of the process, it has evolved over the years to become an industry wide tool.

To reflect the changing approaches to building design, construction and use, and the associated advances in digital technology, increased ethics awareness, and the prioritisation of sustainable outcomes in line with the RIBA 2030 Climate Challenge, it received its biggest overhaul in 2020.

In this article we examine the eight stages of the RIBA Plan of Work 2020. We look at how this formal roadmap, whilst not a contractual document provides vital guidance and helps to deliver successful outcomes for stakeholders by informing the briefing, design, construction, handover, and use of a building.

Each of the eight key stages has an expected outcome; core tasks; core statutory processes in relation to planning and building processes; and crucial information exchanges, all of which impact the success of the next stage.

Stage Zero – Strategic Definition

‘What do you want to achieve from your building project, and what are your best options?’

This stage is not about design or practical details, but rather a chance for us to get to know the client, developing their requirements and helping shape the business case to achieve them.

At this stage all those involved in the client team, alongside ourselves and any other professional advisors must consider that the proposed building project is the appropriate means to meet the client’s stated objectives, and then determine the best way forward.

For example, perhaps a new building is not the answer, and the solution could be refurbishment or an extension.

To come to a decision, information is gathered for each option. This involves examining previous similar projects, the current building if applicable, analysis of project risk (where appropriate site appraisals and surveys carried out), and consideration of project budgets.

We will look at the size, location, scope, and special considerations around the clients’ needs to further refine the vision.

From this exercise a recommendation is made on the best option, and a business case is completed.

Stage One – Preparation and Briefing

‘Developing the initial project brief and setting out the timescales – the official start of the project’

Once it has been determined that the chosen project and site is the best way forward, stage one, is the process of preparing a comprehensive project brief and choosing the collaborative project team, allocating specific roles and responsibilities.

The project team will include:

– Design team – headed up by Lead Designer and overseeing the design programme
 Client team – headed up by Project Manager and overseeing the project programme
 Construction team – headed up by Project Director and overseeing the construction programme

Feasibility studies and site surveys may be required at this stage to test the brief against the chosen site and budget i.e. are there any access issues? Is it a sloping site? What is the spatial overview and relationships with neighbouring buildings?

This is often the time for us to discuss options regarding the site with the local planning authority and make sure there are no constraints. We like to establish clear and positive communication with these departments from the outset.

Discussions around building regulations and other legal requirements should happen at this stage including whether the site is within a listed buildings or conservation area

It is at this point that objectives are finalised and recorded under:

– Project Outcomes
– Sustainability Outcomes
– Quality Aspirations
– Spatial Requirements

Working with the client, we will at the end of this stage, produce a timescale for the project as well as a project execution plan setting out delivery.

Stage Two – Concept Design

‘The design stages begin and the architectural concept is defined ‘

Stage two begins the core design process which culminates at stage four.

We work closely at this stage with the client to produce visualisations, 3D models, and drawings of the architectural concept, ensuring it meets their needs and is aligned to the project brief and cost plan.

As well as a visual representation of the building with sections and elevations and how it sits within the surrounding environment, these will often include:

– Interior and exterior renders
– Landscaping
– Specific requests
– Strategic engineering requirements

There is as the RIBA states ‘no right or wrong approach’ at this point, it is our initial design response to the brief and will involve regular meetings, discussions and reviews with the client and specialist stakeholders including planners and those across structural and civil engineering, to shape and define it.

The robust architectural concept along with the project brief and cost plan are signed off at the end of this stage.

Stage Three – Spatial Co-ordination

‘The co-ordinated design takes form.’

Formerly the developed design stage, here our team draw up the client approved design in CAD or ever increasingly with BIM, and develop and test it alongside detailed structural design, outline specifications, building services and cost analysis to ensure its viability.

Our design will incorporate the practical elements relating to:

– Window, door, stairway, and fire exit locations
– Fixtures, fittings
– Proposed materials
– Load bearing mechanical information
– Mechanical, plumbing, and electrical considerations
– Tech and security
– Green, eco and solar

During this stage, or certainly at the end the design is finalised into a single model, not prone to change, and planning applications are ready for submission incorporating all our detailed drawings and reports.

Arches House – Technical Design Package for Tender Issue

Stage Four – Technical Design

‘Final design stage before construction begins’

We make further refinements of the existing design at this stage, incorporating where relevant detail from specialist sub-contractors such as lighting specialists, kitchen designers or glazing companies.

From this our Lead Architect prepares comprehensive drawings, specifications, and documents for tender.

The level of detail will depend on the size and scope of the project but by the end of this stage all elements will be prescriptive rather than descriptive for the project to be manufactured and built, i.e., they set out detailed descriptions around the following:

– Requirements relating to regulations and standards
– The specific types of products and materials required
– The methods of delivery and installation
– The building systems in place i.e., flooring, partitions, mechanical and structural

At the end of this stage all information required to construct the project is completed and we send out the tender to 3-4 contractors we have worked with before. Of course, should the client want to add to the list we will do so.

Stage Five – Manufacturing and Construction

‘All systems go…construction begins’

The design process is now complete and the appointed contractor takes possession of the site to carry out works as per the schedule of works and building contract. This includes manufacturing off-site and construction on-site.

Stage four and stage five can overlap or run concurrently dependent on the size and scope of the project, or when the contractor was appointed.

The client can choose to appoint us as the contract administrator at this point should they wish. In this role we act as the middle ground between the client and the contractor to ensure that all works are being done in accordance with finalised drawings and specifications. This can entail:

– Chairing construction progress meetings
– Preparing and issuing construction progress reports
– Co-ordinating site inspections
– Dealing with site queries
– Agree reporting procedures for defects
– Issuing project documentation to the client
– Issuing certificates of completion

If appointed, we like to meet weekly with the client and the relevant parties to ensure that everything is running smoothly.

The appointment of Building control by the client should take place, to oversee the project and ensure that all is in order in relation to the necessary construction standards.

Health and Safety inspectors will review and observe the site at this stage, so it is worth considering an independent consultant to ensure that all the correct procedures are followed.

Stage Six – Handover

‘The completed building is finished and handed over’

After practical completion, the building is ready for hand over to the client, and the building contract concludes.

Feedback and building aftercare exercises take place during this stage to act as future learnings for ourselves, the client, contractor, and consultants, and to address any issues relating to the integrity of the building.

These involve light touch post occupancy evaluation and snagging processes, whereby the client compiles a list of defects or incomplete works, overseen by us as the contracts administrator and presented to the contractor to rectify.

They then have an agreed Defect Liability Period, usually six to twelve months to address these, after which if all has been made good, building control will sign off the construction and we will sign off the project as a whole.

We then issue a final certificate, and this stage is complete.

Light House, North Clapham, London

Stage Seven – Use

‘The vision for the building is realised and it is now in use’

This stage starts concurrently with stage six.

The building is now occupied and in use. On most projects, our design team will have no duties to fulfil here.

However, the incorporation of this stage into the RIBA Plan of Work 2020 gives the client the opportunity to get in touch with us if they require general advice relating to maintenance, energy consumption or management of the facilities.

We welcome this communication as we love to hear how the client is finding their new building, and it also allows for effective aftercare, valuable feedback, and building monitoring especially around energy consumption, and is therefore key to the sustainability strategy.

The addition of this feedback stage has made the Plan of Work cyclical as it unites the entire process into one, allowing for proper use of the building and then when demands change, and the building reaches an end of life where refurbishment or a new building may be needed, stage zero starts again.

Embarking on a design and build project can often be a complex one for all involved, for a client it can be daunting.

The RIBA Plan of Work 2020 offers all stakeholders a clear approach to map out the journey collaboratively from vision, through to design, construction and eventual use.

At RISE Design Studios, we find that this straightforward process with realistic and measurable targets, the ability to review progress and a provision for valuable learnings allows for enhanced clarity, greater realisation of vision, and successful outcomes no matter the diversity of projects.

Discover How To Achieve Your Eco Home

“CO emissions from buildings and construction hits new high” announced the headline from 2022’s Global Status Report for Buildings and Construction. Released at COP27, it paints a gloomy picture of the sectors huge rate of energy consumption and emissions.

Accounting for over 34% of energy demand and approx. 37% of energy and process related CO2 emissions in 2021, the sector is further widening the gap between it and the decarbonisation targets of 2050.

However, amongst this negativity there continues to be pioneering work in eco-friendly architecture and smart low energy homes. Once seen as a quirk of the rich or eccentric, these sustainable, affordable, and forward-thinking properties are springing up throughout the country.

As energy bills continue to rise, and the need to reduce carbon emissions becomes even more critical we look at the growth in popularity of these green friendly and environmentally conscious buildings.

The UK legacy of poor building design

As outlined in a recent Guardian article by Phineas Harper, we have in the UK some of the smallest, oldest, and poorest insulated houses in Europe with more than half built before 1965.

This ageing and inefficient housing stock is the result of mass building predominantly in the industrial revolution which saw small, largely terraced two-up-two down, street facing homes, constructed in narrow streets with poor shading and orientation.

With cooler summers and cheap coal used in open fires, environmental performance and extreme weather were certainly not a consideration!

Deregulation has also led to micro homes springing up, created without planning permission from office blocks and commercial buildings with cramp living spaces prone to overheating with no cross ventilation.

Either too hot in the summer or freezing in the winter, these poorly insulated houses now present a major challenge in the fight against climate change, accounting for 66 million tonnes of emissions in 2019 due to burning coal, gas and oil for space heating and hot water.

As the Building Research Establishment (BRE) states: “The UK has the oldest housing stock in Europe, and most likely in the world. This is largely due to the legacy of dwellings built during the industrial revolution, which still form the backbone of our urban areas today.”

“While still widely valued, these homes present challenges in making them healthy, safe and suitable for the future.”

Whilst new build homes can go some way to offering a solution, the homes which make up most of the country’s stock require retrofit to make them not only habitable, comfortable, and visually appealing for the future, but also to achieve energy efficiency and climate targets.

A zero carbon or low carbon home

When it comes to sustainable architecture and eco homes, there are two main routes to consider, these are zero carbon and low carbon.

Both focus on energy conservation and efficiency through elevated levels of insulation, high performance triple glazed windows, airtight building materials, thermal bridge free construction and mechanical ventilation systems.

The main difference is that in the design of a zero-carbon home the aim is to produce no carbon dioxide through its energy use whereas a low carbon home reduces its emissions to a much more acceptable degree compared to the average property.

What are the design elements of eco homes?

The unveiling of the UK’s first net zero home took place recently in Camden Town.

The UK Green Building Councils Framework awarded the Max Fordham House this accolade in recognition of its emissions as well as its use of natural materials including low carbon cement, timber for the roof, window frames and façade, and wood fibre and cork flooring for internal insulation.

The all-electric home also features a roof-mounted PV to meet 25% of its energy needs with the remaining supplied by a 100% renewable energy tariff.

Much of what it achieved was through the Passivhaus standard of design and construction (or EnerPHit for retrofit). Here the focus is on superb thermal performance, stringent levels of airtightness, minimal thermal bridging, optimisation of passive solar gain, and mechanical ventilation with heat recovery, resulting in homes with a comfortable temperature and minimal energy use, 75% less than a standard home. Heat is generated via sunlight, inhabitants, A+++appliances and LED lighting.

Whilst you may not wish to fully adopt the exacting standards of Passivhaus (or EnerPHit), particularly dependent on your regional climate, home orientation/shape, and whether it’s an existing or listed property, at RISE we will work with you to incorporate a variety of design principles into your new build, refurbishment, or retrofit to create a sustainable home.

  1. Creating an efficient thermal envelope

Insulation is fundamental to any eco home as it has a major impact on heat gain as well as heat loss, and therefore on energy consumption.

Passivhaus design ensures that through insulation levels any heat lost during winter is negligible and that indoor air and surface temperatures are almost similar, ensuring a comfortable climate.

Exterior walls, basements and attics across all homes can benefit from this approach and use less energy, with high performing, non-toxic and renewable insulation such as sheep’s wool, wood fibre, and hemp used to trap heat and create a thermal envelope.

  1. Energy efficient glazing

It is unsurprising that one of the biggest culprits of heat loss from the home is glass with a typical home losing 10%. Whilst Passivhaus requires optimised glazing on the south façade of a property with reduced glazing on the north, if you are looking at a retrofit you can make improvements.

The energy efficiency of a window is measured with its U-value, the lower the number the better. Whilst double glazed windows are normally 1.6, triple glazed can sit at an impressive 0.8 with an energy rating of A++, the highest possible rating and recognised by the Passivhaus Institute as the acceptable standard.

With three sheets of glass, and two gaps, triple glazing your windows where possible, can improve insulation, reduce energy bills, and carbon emissions.

Although costly at the outset they will bring with them multiple benefits for your home especially when fitted to the south-facing side.

Additionally, look at passive design techniques to help create external shade and reduce heat transfer from these windows in summer, such as awnings and overhangs as well as trees and landscaping. This will not affect the heat gain from the low sun in winter.

  1. Renewable Energy Features

Solar energy, heat pumps and biomass boilers are all examples of renewable energy that you can incorporate into the home.

Each allows you to generate your own energy without reliance on traditional sources such as polluting fossil fuels. This then helps to create a carbon positive home in which a building produces more energy than it needs, sending surplus back to the grid.

  1. Greener Construction

This may apply more to a new build project but is also a consideration where applicable for elements of an energy efficient retrofit. Greener construction includes a number of variables and is not just based upon using recyclable materials.

It is part of what makes a carbon positive home, one which uses sustainable building materials to reduce emissions related to production, transportation, and installation.

Consider where the product was made, how it was made, and how far it had to travel to reach site. If we look at the BedZED village, the UK’s first mixed use sustainable community completed in 2002 they were able to use 52% of their materials from within 35miles.

In addition, look at whether you can use reclaimed materials. The same project used, 3,400 tonnes of reclaimed and recycled material representing 15% of the total. For a domestic project this could comprise any manner of things from doors, tiles, and bricks to bathtubs and light fixtures.

Finally, see where you can make changes by selecting eco-friendly and sustainable alternatives, such as those we touched upon relating to insulation as well as bamboo, cork, straw and hempcrete.

  1. Airtightness

For a truly eco-friendly and low carbon home airtightness is a major consideration. This represents the fabric first approach to buildings that are less reliant on space heating.

It focuses on the leakage of air from a house, escaping through gaps and cracks in the fabric of the property. In terms of Building Regulations this means that no more than 10 cubic metres of air can escape per hour for every square metre of the envelope surface area.

To put this into perspective a house achieving 5 cubic metres will see their energy use reduce by up to 40%.

Whilst we talked about windows and insulation earlier, it is also important to look at door frames, open fires and chimneys, pipes, and cables.

The use of specific materials for membranes and barriers such as long-lasting flexible mastic is also key. If constructing a new home, then eco-friendly structurally insulated panels (SIPs) made from timber are a positive choice, manufactured off-site they can help to reduce carbon emissions.

  1. Natural and Mechanical Ventilation

To maintain a healthy and comfortable internal environment in an airtight home, ventilation is a crucial factor.

Airtight properties will often rely on mechanical ventilation with heat recovery (MVHR) systems as well as skylights and natural cross ventilation with windows on each side of the home creating a cross breeze, although the latter is harder in winter and will exacerbate heat loss.

MVHR take moisture from rooms such as bathrooms and kitchens, passing it through heat exchangers which in turn combines it with fresh air coming into the home, releasing this pre-warmed air back into the property.

As it requires ducts to run through the building it must comply with building legislation in terms of installation, design, and inspection, and we can advise you on this.

How an architect will help you achieve your eco home

As you can see whether retrofit, refurbishment or new build there is much to consider when it comes to creating a liveable and comfortable eco home. Here at RISE, we have the experience and skill to help you to achieve your vision.

Our passion in this area has seen continual professional development undertaken across the team with a focus on the EnerPHit standard developed by the Passivhaus Institute. Still a very demanding standard it does relax part of the criteria, recognising the challenges of retrofit projects.

Client led, we look at not only the design and construction of the building, but its eventual end use to ensure that the sustainable house you create is also a home.

Heat Pumps – the future of home heating?

Unless you have been hiding, you could not fail to realise that UK energy bills are at an unprecedented level. If we believe the press and general whisperings, then predictions are they will triple by 2023 reaching £5,000 for an average household.

These are indeed worrying times and it is no surprise that consumers are turning to low-energy solutions for daily tasks such as cooking, and drying clothes. Of course, the biggest outlay as we approach the UK winter is heating.

The economic crisis as well as greater emphasis on renewable energy to reach net zero emissions by 2050, has shone a light on alternatives to traditional energy with demand growing for solar panels, green roofs, and heat pumps.

With 190million heat pump units in operation worldwide in 2021, global sales increasing by 13% and The International Energy Agency’s latest report stating that no new gas boilers should be sold after 2025 we examine their growth, the advantages they bring to a residential project and what kind of investment they entail.

What are heat pumps?

In its most basic sense, a heat pump is a highly efficient energy device which takes heat or thermal energy from outside and moves it into your home using electricity. During warmer temperatures you can use some systems as a cooling device like air-conditioning.

The amount of power it uses is far less than the quantity of heat it provides, this is known as the Coefficient of Performance (CoP). If a heat pump has a CoP of 3.0 then it will give out three units of heat for every unit of electricity consumed.

Using existing heat means that it does not burn any fuel and therefore emit any carbon dioxide. It is for this reason that it is an incredibly efficient method of heating and has the potential to reduce energy bills.

What are the different types of heat pump?

There are two main types of heat pump available air source heat pumps (ASHP) and ground source heat pumps (GSHP).

Both work on the same principle to transfer heat but differ in the source of that heat. Which you choose depends on budget, installation, efficiencies, and your home.

  • Air source heat pump

These are the most common system in the UK for domestic homes representing 87% of all heat pumps installed. You fit an air source heat pump (ASHP) to the outside of your home, either to the front, side or the rear (planning permission may be required).

With this system the heat from the external air is used to heat your home/hot water by pumping it through a system of refrigerant filled coils fitted to the outside of the unit (the evaporater), like those you find behind your fridge.

The liquid in the coils absorbs the heat and as it warms up begins to evaporate, this gas then goes through a compressor to increase the temperature. The coil then moves inside the building releasing the heat to inner coils which heat the house and/or water that supplies radiators, showers, taps etc. The refrigerant flows back outside to absorb more heat and the process begins again.

An air source heat pump can extract heat from temperatures as low as -15degrees Celsius to provide heating all year round.

There are two distinct types of air source heat pump (ASHP), air-to-air and air-to-water.

Air-to-air heat pumps: these take external heat and transfer to your home through fans or blowers. A warm air circulation system then moves it around your home.

They cannot heat hot water so you would need to look at an alternative such as an immersion heater. In the summer they work on reverse like an air conditioning unit.

They tend to be an excellent choice for smaller properties and are quick to install as they don’t require radiators or underfloor heating.

Air-to-water heat pumps: these take heat from the air outside and feed it into your water-based central heating system and your hot water cylinder to store hot water for when you need it.

As it has a lower heat supply than gas or oil boilers, 35degrees to 45 as opposed to 75degrees, an air-to-water heat pump is used most efficiently with large or double panel radiators or underfloor heating which have a greater surface area.

  • Ground Source Heat Pump (GSHP)

These take heat energy from pipes beneath the ground outside your home to power your heating and hot water.

Thermal transfer fluid (TTF) or brine, a combination of cool water and antifreeze flows around the loop of pipe buried in the garden or outdoor area. The pipe absorbs the heat from the ground into this fluid which then passes through a heat exchanger into the heat pump. This action raises the temperature of the fluid and transfers the heat to water.

The ground stays at a constant temperature below the surface allowing the ground source heat pump to work efficiently all year.

You will need quite a large amount of garden or ground to use a GSHP.

What are the benefits of heat pumps?

It is hard to ignore the popularity of heat pumps particularly in their ability to reduce energy bills as well as lowering carbon footprint.

There are a variety of additional benefits that will no doubt see demand continue to grow, as they become an increasingly attractive alternative to gas boilers.

  • Lower running costs –recent reports from the National Endowment for Science and the Arts (Nesta), state that a heat pump can reduce household gas consumption by up to 70% when compared to a gas boiler.
  • Reduces carbon emissions – as heat pumps use little electricity, they produce no emissions making them environmentally-friendly. They are also extremely sustainable as they are using natural heat sources whether from the ground or air.
  • Easy installation – it can take as little as two days to install an ASHP this might increase slightly with a GSHP due to the requirement to excavate slightly.
  • Longevity – a modern heat pump usually has a life span double that of a domestic boiler, on average 20-25 years, future proofing your home both economically and environmentally.
  • Less maintenance – they have very few moving parts, with yearly checks advised but they can be carried out by the owner such as clearing leaves, dust, and cleaning filters. A certified professional installer would need to visit every 3-5 years to look at any technical aspects.
  • Safety – as they rely on renewables and electricity as opposed to fuel, and with few moving parts, they are a safer choice than traditional systems.
  • Eligible for Government incentives –there are financial incentives for installing heat pumps which we will outline.

How much does a heat pump cost?

It can be expensive to install a heat pump, but this will depend on the type you choose, your installer, the size of your home, its insulation and running costs. A typical price for a full installation is between £7000 and £45,000.

Air to water heat pumps start at approx. £7000 reaching £18000, whereas ground source heat pumps can cost up to £45,000.

Although upfront costs are high, switching from your previous system should save you running costs in the long-term dependent on your tariff, which system you use, your home and its central heating system.

The Boiler Upgrade Scheme launched in England and Wales helps homeowners afford the upfront costs of installing low carbon heating systems such as heat pumps with grants of £5000 available. Open until the end of March 2025, the work must be carried out by an accredited MCS installer.

There are eligibility criteria including that you must own your home, and it needs an up-to-date Energy Performance Certificate (EPC).

Do I need planning permission for a heat pump?

Due to Permitted Development Rights, in most cases it is unlikely that you will need planning permission if installing a heat pump.

However, it is of course dependent on the property and the local planning department. This is especially important if the property is listed or within a conservation area.

You will have to inform your local district network operator (DNO) that you are installing a heat pump as they are responsible for bringing electricity from the network to your home. Your installer will advise on this.

Here at RISE Design Studio, we can help with any discussions you may need to have.

How an architect can help with a heat pump

Whilst most homes and residential projects will not require planning permission to install a heat pump, it is worth appointing an architect if you are keen to pursue it.

Whether you require planning or not, there are certain things to bear in mind should it be a retrofit, refurbishment, or new build project which may have other installations taking place:

  • What will the aesthetic impact be with regards to an ASHP that fits to the side of your property?
  • You will need to ensure no trees etc block its position
  • Positioning of the ASHP will need to be in a sheltered spot
  • A GSHP will require groundworks, these could be disruptive, so you want to ensure you carry these out correctly
  • If you wish to install an underfloor heating system

As we continue to navigate this unchartered territory of rising energy costs, and we look to do more to achieve sustainability, the growth of alternative energy technologies such as heat pumps is no longer niche but rather an inevitable part of our future.
