Why Build an Eco-Friendly Extension?
Building sustainably is about more than just “going green”—it’s about future-proofing your home.

1. Use Sustainable Building Materials ♻️
Choosing the right materials is the first step to an eco-conscious build.
✨ Eco Alternatives:
-
Reclaimed bricks and timber
-
FSC-certified wood
-
Hempcrete and lime plaster
-
Low-VOC paints and finishes
✨ Smart Swaps:
-
Swap concrete for recycled steel supports
-
Choose bamboo flooring over hardwood
-
Use recycled glass for splashbacks or countertops
2. Maximise Natural Light ☀️
Reducing your reliance on artificial lighting is key.
✨ Design Tips:
-
Incorporate skylights, solar tubes, or full-height glazing
-
Position windows to optimise passive solar gain

Use light wells and internal glazing to transfer daylight between rooms
3. Insulate Everything Properly ❄️
Heat loss is one of the biggest contributors to inefficiency.
✨ Eco Insulation Options:

Sheep’s wool
-
Wood fibre

Recycled denim or cellulose
-
Expanded cork boards
Don’t forget to insulate walls, floors, and roofs thoroughly—especially if retrofitting older properties.
4. Choose Energy-Efficient Windows & Doors 🪟
Install double or triple-glazed windows with low-emissivity coatings. Opt for airtight frames and consider composite doors with recycled content for minimal heat transfer.
5. Incorporate Renewable Energy Where Possible ⚡
Depending on your budget and location, you could integrate systems such as:
-
Solar panels
-
Air-source heat pumps
-
Rainwater harvesting systems
-
Underfloor heating with smart zoning
While upfront costs can be higher, the long-term benefits are well worth it.
