The Queen’s Park neighbourhood and conservation area is an important historic area, with a high level of preserved Victorian housing dating back to the late 1800s. The area’s urban layout is distinguished by its cohesive design centered around the park, which is a good example of a Victorian urban green space. The streets surrounding the park largely comprise of original two and three storey Victorian houses. Gentrification of the neighbourhood began gradually at the turn of the millennium, but in recent years it has accelerated, notably in the 2010s. Pre pandemic has brought a new wave of residents to the neighbourhood, drawn by its lower house prices compared to nearby areas such as Notting Hill, Ladbroke Grove, Belsize Park, St John’s Wood and Hampstead.

Each project we work on teaches us that crafting an energy-efficient, beautiful home, akin to creating a symphony, requires an intricate dance of various elements, each resonating with its unique rhythm. At RISE Design Studio, our chief focus is woven around the harmonious union of contemporary design, low energy consumption, and reduced embodied carbon.
As the real effects of climate change becomes increasingly palpable, the demand for sustainable homes is skyrocketing, compelling both the construction industry and homeowners to modify their stance and tune into the rhythm of the Earth. However, rest assured, constructing a sustainable residence doesn’t mean compromising on visual elegance or the comfort and health of the residents.
The goal of this expanded discourse is to equip you with a more comprehensive understanding of the critical facets that underpin sustainable architecture, and how they align to conjure up the magic of a low-energy, aesthetically pleasing, and sustainable dwelling. The insightful knowledge will prove invaluable as you stride forth to manifest your sustainable, eco-friendly abode.
Mill Hill House, a new build home in North London that follows Passivhaus principles
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.

Frequently Asked Questions
Q1. What is Passivhaus design?
Passivhaus design is a gold standard for energy-efficient homes, aiming to achieve comfort with minimal energy use. It taps into passive energy sources such as sunlight and heat generated from people and appliances to dramatically minimise the need for auxiliary heating.
Q2. How important is building orientation in eco-home design?
Building orientation is critical in sustainable home design. If you’re in the Northern Hemisphere, your home should face south, with most windows positioned on this side to maximise solar gain. Strategic shading can prevent overheating during summer, with solutions like extended eaves and well-positioned external blinds.
Q3. What is the U value in the context of eco homes?
The U value measures the rate at which heat escapes a building. The lower the U value, the slower heat dissipates. Materials with a lower U value help retain heat in the house, reducing the energy needed for heating.
Q4. What is airtight design in eco homes?
Airtight design refers to the practice of ensuring minimal air leakage from a building. In eco homes, an airtight design helps maintain a comfortable temperature by reducing heat loss. It’s achieved by using airtightness tapes and membranes across all elements of the building.
Q5. What is the role of natural ventilation and heat recovery systems in eco homes?
Natural ventilation helps maintain a comfortable temperature by allowing air to flow through the building. Meanwhile, heat recovery systems, often incorporated in airtight designs, help maintain indoor air quality. They extract heat from the warm air in spaces like kitchens and bathrooms, transfer it to fresh incoming air, and release it back into the living areas.
Q6. How can I manage energy use and efficiency in eco homes?
A combination of strategies helps manage energy use and efficiency. These include the use of A+++ rated appliances, LED lighting, and active solar measures, such as photovoltaics, to meet electricity needs. Proper insulation, solar orientation, and efficient hot water heating systems also contribute to energy efficiency.
Q7. How do eco homes handle water, drainage, and waste?
Eco homes incorporate water-saving measures like low-flush plumbing and water recycling systems. They also employ alternative waste management systems, like composting toilets. Heat loss considerations during the installation of water systems and effective handling of household waste, like recycling, are essential aspects.
Q8. How adaptable should an eco home be?
A truly sustainable home should be flexible and ready for different eventualities. In light of our rapidly changing climate, it’s crucial that eco homes require minimal external power to operate and have features that enable them to weather literal and metaphorical storms.
Q9. What role does the environment play in the design of an eco home?
Sustainable home design takes into account the building’s context. A truly zero-carbon home would encourage a zero-carbon lifestyle, including provisions for food production, bicycle storage, flexible workspaces, and other environmentally friendly features.

The Lexi Cinema & Hub has been shortlisted for the London Borough of Brent’s first celebration of design excellence.
The Brent Design Awards are new for 2023 and have been created to celebrate the great buildings and places within the culturally diverse borough of Brent.
The Lexi Cinema & Hub is in the running for the Culture & Heritage category. The Lexi is also in the running for the People’s Choice Award.
The Lexi Cinema & Hub – Shortlisted for Brent Design Awards
A treasured asset within the local community, The Lexi Cinema tasked RISE Design Studio with revitalising a 99 square metre parcel of vacant land in the rear car park of the existing Edwardian gabled brick theatre. Used as a makeshift bar by locals, RISE Design Studio and The Lexi team consulted Brent Council who advised the initial concept, a formal beer garden, would not be possible due to noise constraints but an enclosed second screen might be feasible.
RISE Design Studio conceptualised an environmentally-driven second cinema and bar to accommodate the growing community programme and help drive revenue for The Lexi’s ecological charity efforts. Brent Council were instrumental in supporting the project – titled The Lexi Hub – through continuous advisory and dialogue, ensuring planning policy and community needs were balanced.
The People’s Choice Award allows residents and those working in Brent to choose their favourite building or place, from a shortlist of 27 entries across 5 different categories. The winner of the People’s Choice Award will be announced at the awards ceremony taking place at Brent Civic Centre on 11th May 2023.

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.
RIBA Plan of Work 2020
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.
Mill Hill House – Concept Design Sketches
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.
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.
Briefing for Buildings: A practical guide for clients and their design teams
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.
Herbert Paradise, Kensal Rise, North West London
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.
Herbert Paradise during Construction, Kensal Rise, North West London
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.
Burrows Road Glazed Envelope, Kensal Rise, North West London
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.
“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.
Herbert Paradise, Kensal Rise, North West London – Low Energy Home
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.
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.
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.
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.
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.
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.
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.

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.

Living roofs or green roofs, were until recent years a rarity in the UK building landscape, seen as a luxurious design addition implemented by the few with adoption much greater in countries such as Switzerland and Germany.
Today, alongside other forms of sustainable architecture and design, or green technology, they are growing in popularity.
Seen as not only aesthetically pleasing in densely populated urban areas, but increasingly as a method to reduce energy use and carbon emissions, they are key along with green walls, roof terraces, and solar to improving our resilience to climate change and safeguarding our environmental future.
Green roof provision has grown considerably across the capital as shown in the 2019 London Green Roof Report this has been in part to key policy drivers like the 2008 amends to the London Plan, stating in planning policy 5.1 ‘the Mayor will, and boroughs, should expect major developments to incorporate living roofs and walls, where feasible’ .
With this in mind, we examine green roofs, the distinct types, the benefits they bring, architectural and design considerations, and the future outlook.
The Lexi Cinema extensive green roof
What are green roofs?
Installed on flat or low-pitched roofs with an angle of no more than 30degrees, green roofs also referred to as living or eco roofs are found on small residential buildings through to large commercial and industrial buildings.
They consist of engineered soil (substrate) especially designed to hold the correct amounts of moisture, nutrients, and air for successful plant growth. They are either intensively or extensively planted with vegetation, then laid over a waterproof membrane or moisture retention fleece to prevent leakage and remain watertight in all conditions.
As well as these elements, a typical green roof layer/system will consist of a root barrier, thermal insulation, and drainage/irrigation systems.
They offer minimum or maximum levels of pedestrian access and use dependent on space and roof structure, and with grasses, herbs, mosses, and wildflowers can improve biodiversity by providing a habitat for birds, and insects.
In addition, they have an array of environmental benefits which we will discuss further on.
What are the different types of green roof?
There are three main types of green roof, intensive, extensive, and semi-intensive. Each differ and are unique in terms of use, maintenance, design implications, weight, and cost.
Intensive green roof
You will typically see an intensive green roof or roof garden designed for accessible recreational use on large commercial buildings such as those at Jubilee Park in Canary Wharf, 55 Broadway, or at New Providence Wharf in Docklands which covers an area of 8.3 hectares. Prince of Wales Drive is a good example of an intensive green roof in a residential setting.
Due to the scale of an intensive green roof and with its tendency to feature extensive lawns, trees, paved areas and even water features they can weigh a significant amount and usually need to be designed with a heavy-supporting structure typically with reinforced concrete to take a load of up to 200kg/m2.
The soil on an intensive green roof is planted quite deeply at over 200mm and once planted are labour intensive requiring regular maintenance, fertilisation, weeding, and pruning.
Due to their need for regular watering, they will have dedicated rooftop irrigation such as a dripline system laid below the soil surface at root level.
Considering all these factors, they are the costliest green roof.
Extensive green roof
Compared to intensive green roofs, extensive systems are lighter in weight (40-110kg/m2) and are shallower ranging from 2cm to 12cm in depth, because of this they require less maintenance normally just once a year weeding, are less costly, and can be self-sustaining.
Their shallow depth means that extensive green roofs in London and the UK tend to comprise of hardier sedum or stonecrops. Sedums are low growing succulents (which store water) which look to be sitting on the soil, with the word coming from the Latin ‘sedeo’ which means to sit.
It is because of their shallowness that they do not add great weight to a roof, they also tend to be drought and frost proof which means they require little watering.
Easier to implement, a popular choice is to use a pre-grown sedum mat-based system incorporating a variety of plants and flowers. Delivered as a roll, they are typically, 20mm thick, and laid out onto crushed brick or light clay aggregate, with a waterproof layer often on top.
They are a good option in comparison to loose planting which is more labour intensive as it involves preparing the ground, laying the soil, sowing seeds, and then maintenance. However, there are UK nurseries that now supply plants and advice for green roofs
Due to their minimal maintenance, and relatively low cost, extensive green roofs are the preferred choice for residential properties. Although you can find them in commercial settings such as at Canary Wharf which has 5000 to 6000 square metres incorporating five extensive green roofs. This makes it one of the largest green roof spaces in the UK.
Here at Rise Design Studio we used a sedum roof on our Lexi cinema project in London’s Kensal Rise, with our work being shortlisted for a prestigious 2022 FX International Interior Design Award.
Semi-intensive green roofs
These are of course a cross between intensive and extensive green roofs, with slightly greater depth than the latter.
They include a wider variety of plants compared to an extensive green roof, often akin to a wildflower meadow, therefore they require moderate maintenance, fertilisation, and watering.
What are the benefits of green roofs?
Whilst appealing in terms of breaking up the monotony of the urban landscape, along with the resultant inner-city opportunities for recreational and social green space and general improvement in wellbeing and productivity, the principal benefits of green roofs are extensively environmental.
They help to improve and preserve urban biodiversity by creating habitats for animals, birds, butterflies, and insects. Some of which may be endangered and at risk of extinction such as Black Redstarts whose preservation was a part of the driving force behind many early London green roofs
They help to cool building temperature and improve insulation by absorbing heat therefore reducing the ‘urban heat island’ phenomenon, decreasing surface air temperature by up to 16.4 degrees
They improve air quality by producing oxygen
They can contribute to reduced air pollution by removing harmful toxins from the air including nitrates and carbon dioxide
Help to reduce flooding and improve stormwater management, as they can absorb anywhere between 50% and 100% of rainwater, and then release it through condensation and transpiration
Reduce the need for air conditioning and heating requirements leading to less emissions and more efficient energy consumption as they cool the building in summer and warm it in winter
Improve noise and sound reduction
They can produce opportunities for urban agriculture
Such is their environmental impact, that the UK Green Building Council has called for all new buildings and infrastructure to have ‘nature-based solutions’ such as green roofs, by 2030 to combat the ever-growing threat of global warming.
In addition to this, other benefits are that a green roof can add value to your property due to its appearance and the fact it contributes to reduced energy costs, as well as roof longevity by protecting it from natural exposures.
Green roofs in London
In comparison to major cities worldwide London has been ‘late to the party’ when it comes to green roofs. Much of this down to policy implementation, or lack of.
However progression was made with the 2008 amends to the London Plan, the spatial development strategy for Greater London, which saw a much more proactive approach to green roof adoption and greater policy towards urban greening as a whole.
This was echoed by the 2019 creation of the Urban Greening Factor by the Greater London Authority (GLA) which measures the quantity and quality of greening on any new development proposal at the planning stage.
The effectiveness of both of these measures is demonstrated by the recent City of London monitoring reports, on the subject, which show that between 2011/12 and 2019/2020, green roofs went from 23 to 64, covering an area, from 8,200m2 to 25,900m2. This London City Hall map shows the location of these green roofs.
City of London projects that in 2026, green roof spaces which are predominantly extensive will comprise of 82.
There are currently a number of major innovative new green developments planned for the city such as Google’s new Kings Cross headquarters which promises to have a ‘grass-laden plateau’ and ‘green walkways’ as well as an extension to Blackfriars Crown Court which will be topped by a 100-tree forest and a retail development in Greenwich which is to have one of the largest green roofs in the borough.
Nationwide the Government are set to launch further incentives related to planning through The Environment Bill which contains a provision that all planning applications increase the biodiversity of the site in question by 10 per cent. The aim is to leave nature in a better state than before.
How much does a green roof cost?
Costs will vary dependent on the green roof system and the property in question, and whether professional contractors or landscape designers are employed
A professionally designed and installed extensive residential green roof can cost from £50 to £100 per square metre.
This cost is just an average and it will depend on things such as whether the roof needs extra support, how accessible the roof is, and which plants you are using.
Do I need planning permission for a green roof?
Due to Permitted Development Rights, in most cases it is unlikely that you will need planning permission if installing a green roof on an existing residential building, such as a garage or garden shed.
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.
Building regulation approval will be needed if it is a new build or an extension/alteration to a current one, this is due to load capacity and fire regulations.
As part of a new build planning application for large-scale developments, they can be beneficial in terms of gaining credits with BREEAM (Building Research Establishment Environmental Assessment Method) which assesses a building’s environmental performance.
How an architect can help with a green roof
Green roofs are becoming a significant part of architectural design and innovation, after all design is about more than creating buildings of beauty but rather achieving multi-functional buildings that add to and enhance people’s wellbeing and their surroundings, for present and future generations.
When considering a green roof for your home or property, employing an architect such as our team at Rise Design Studio, will help ensure that you get the desired effect and result with all implications considered in reference to the Green Roof Code of Best Practice:
They can help you understand the slope of the roof, maximum load capacity (when saturated, snow covered or through pedestrian access), and structure
Which green roof system will work best for your vision, location, and use, based on the above
They will look at orientation, wind exposure, sunlight, and shading
Examine the impact on areas such as skylights, vents, and chimneys
Determine what planning permissions are required if any
How roof access and egress will work based on safety and the system you employ
Offer guidance on the most appropriate water management and drainage
Specify fire safety requirements as related to building regulations
Help advise on external contractors/manufacturers, and manage that process and overall project management
Look at the proposed maintenance schedule
There is no doubt that green roofs look great and it is not surprising to see their popularity grow, but more than their aesthetic appeal, they sit alongside solar, and wind turbines, as sustainable energy solutions that counteract greenhouse gas emissions and encourage biodiversity.
We each understand that climate change is happening now, employing a green roof whether it be on a home or commercial building is a step to addressing this challenge. It is positive to see that the Government is keen to increase the uptake and prevalence of them especially in larger cities.

In March this year, the UK Government removed the requirement for VAT on payments related to the installation of certain energy saving materials in residential property in Great Britain (England, Wales and Scotland). This will be in place until the end of March 2027. Scrapping VAT on green home improvements for the next five years is a welcome move from the government and should mean that more people will be able to afford to improve the energy efficiency of their home.
Reducing carbon emissions
The UK Government has committed to achieving ‘net zero’ emissions by 2050. In practice, this means reducing carbon emissions by 78% by 2035 (using the 1990 levels as the baseline). Although this is a legally binding commitment (which should be applauded for its ambition), it is meaningless if no actual action is taken.
Reducing the use of fossil fuels in our homes is an important step on the road to net zero. Over 90% of residential property in the UK is still heated using gas and/or oil, the emissions from which accounts for nearly 20% of all UK carbon emissions. The current cost of living crisis also highlights the unsustainable nature of these types of fuel, particularly when prices are pushed up by global crises such as war, which impact on non-renewably energy supply chains.
Strong support but high costs
There is a huge amount of support amongst the British public for the use of renewable energy in our homes. The growing popularity of ‘green energy’ suppliers is testament to this. Increased awareness of the impacts of climate change, alongside rapidly rising energy prices, strongly motivate us to try to reduce our energy consumption and increase efficiency. However, the uptake of renewable energy installations to provide electricity and heat has been slow. For example, only 36,000 heat pumps were installed in 2020.
This is because the initial cost of installing energy efficient technology and moving away from the use of fossil fuels can be very high. These costs are even higher when VAT is part of the cost. It is therefore good news that the removal of VAT will bring the initial costs down somewhat and, hopefully, make greener electricity and heating accessible to more households.
Still more to be done?
At the time of the change in rules, it was estimated by the government that the removal of VAT on green home improvements would save homeowners installing rooftop solar panels around £1,000 a year (on average). Installing solar panels (or heat pumps or improving insulation) would also save an average of £300 a year on energy bills (although this figure may now be even higher in the context of the increasing prices).
While welcome, there is arguably still more work to be done to enable households that cannot afford new installations to make green improvements to their homes. Removing VAT is unlikely to be the ‘one size fits all’ solution it perhaps set out to be. Now is the time to develop and commit to a national retrofit strategy that would invest in improving all existing housing stock to ensure we all live in healthy and climate smart homes.
