How to Plan Your Eco-Retrofit: A Step-by-Step Guide

Transforming your home through an eco-retrofit isn’t just about saving energy - it’s about reshaping how you live. At RISE Design Studio, we believe the best homes are those that work in harmony with the environment while enhancing the day-to-day experience of their inhabitants.

This guide is here to help you navigate the eco-retrofit process, step by step, with practical advice and a dose of inspiration. Whether you’re dreaming of cutting-edge sustainability or simply a cosier, healthier home, we’re here to show you how to get there.

Step 1: Find Your Why

Before diving into the nuts and bolts of an eco-retrofit, take a step back. Why are you doing this?

Maybe it’s the lure of smaller energy bills, the desire to tread lightly on the planet, or the dream of a home that wraps you in comfort, whatever the weather. Whatever your reasons, they’ll guide your decisions and keep you motivated when the process feels daunting.

Step 2: Take Stock

Every great transformation starts with a good assessment.

• Walk through your home and identify the issues. Are there draughty windows? Rooms that are too hot in summer and too cold in winter?
• Take note of your energy consumption. An energy audit can reveal where your home is losing the most heat (and money).

It’s also worth thinking about your home’s quirks and constraints. For example, at Herbert Paradise, we were dealing with splayed floor plans on an irregular site. This kind of detail might seem small, but it has a big impact on design decisions.

Step 3: Dream Big, Plan Smart

Now’s the time to imagine your ideal eco-home. What does it look like?

• Is it filled with natural light, with spaces that flow seamlessly from one to another?
• Does it use sustainable materials like reclaimed timber and natural insulation?
• Are the heating, ventilation, and cooling systems so efficient you barely have to think about them?

At this stage, technology can be a game-changer.

We use tools like BIMx (Building Information Modeling) to create a digital twin of your home. This is more than just a 3D model - it’s an interactive experience. Imagine walking through your future home on a tablet, like a computer game. Or slipping on VR goggles to experience the design from every angle.

For Herbert Paradise, this technology was invaluable:

• Stakeholder Collaboration: Clients, structural engineers, party wall surveyors, and contractors were able to review the project at all stages of design. This meant they were informed and aligned before a single brick was laid.
• Exploring Options: From the early stages, we showed various design options in 3D. Clients could walk through different layouts and pick their favourite - or combine elements from multiple designs.
• Ongoing Updates: Once a direction was chosen, the proposals were continually updated. The client always knew how each space would look and feel, reducing surprises later.
• Clash Detection: During construction, we used the digital twin to map out MVHR ducting routes, ensuring they wouldn’t clash with structural elements. This dramatically reduced conflicts on-site, saving time and money.

Step 4: Budget with Purpose

Eco-retrofitting isn’t just an expense - it’s an investment in your future.

Here’s a rough breakdown of costs to help you plan:

• Quick Wins (e.g., draught-proofing, LED lighting): £500 – £2,000
• Medium-Term Upgrades (e.g., insulation, double glazing): £5,000 – £15,000
• Major Investments (e.g., solar panels, heat pumps): £10,000 – £30,000

Grants and incentives can help offset some of these costs, so do your research. And remember: every pound spent now is a step toward lower bills and a higher resale value.

Step 5: Build Your Team

The best projects are collaborative.

You’ll need architects, engineers, and contractors who understand the art and science of sustainable design. At RISE, we specialise in bringing these elements together, ensuring that every detail - from the ducting routes to the finishing touches - aligns with your vision.

Step 6: Phase Your Retrofit

Rome wasn’t built in a day, and your eco-retrofit doesn’t have to be either.

Here’s how you might phase your project:

1. Immediate Wins: Tackle the small stuff first - draught-proofing, switching to energy-efficient appliances, or upgrading to LED lighting.
2. Mid-Level Upgrades: Focus on insulation, glazing, and energy-efficient heating.
3. Big-Ticket Items: Install solar panels, a heat pump, or an advanced ventilation system like MVHR.

Step 7: Technology for Transformation

Technology doesn’t just make retrofitting easier - it makes it smarter.

Using digital twins, we can predict and solve potential issues before construction begins. This was especially critical for Herbert Paradise, where the unusual shape of the floor plans required careful planning to make the most of every inch of space.

The result? A retrofit that didn’t just meet expectations - it exceeded them.

The Challenge

The site’s irregular, splayed shape created unique challenges, requiring meticulous planning and collaboration between the client, engineers, and contractors.

The Solution

By leveraging BIMx, we:

• Showed the client multiple design options in 3D and VR, allowing them to make informed decisions about layouts and finishes.
• Worked with the structural engineer to map out MVHR ducting routes, avoiding clashes with the structure during construction.
• Kept the client informed throughout the process, with real-time updates that eliminated uncertainty.

The Results

• A 75% reduction in energy consumption.
• A home that’s as beautiful as it is efficient.
• A smoother construction process, with fewer delays and conflicts on-site.
