Our Sustainable Building Process
At London Garden Rooms we’re committed to building sustainably. Our process is carefully designed to ensure the lowest environmental impact, whilst still delivering the value for money you expect.
“Our philosophy is to build with the most durable materials, using the fewest possible resources”
We install our garden rooms on large, galvanised steel screw foundations, not on a traditional concrete base. We were one of the first companies to use this method, and it’s now widely adopted by the building industry. Not only is this approach more versatile, durable, and stronger, but also significantly more environmentally friendly:
- Minimal groundwork preparation – avoiding damage to landscape or trees
- Reduced installation disruption – electrical tools only, no plant hire with associated cost and noise
- Recycling potential – steel foundations can be reused or recycled if needed
Our roofing systems use the Firestone RubberGard EPDM membrane, the market-leading sustainable garden room roofing solution. EPDM is an inert material with limited environmental impact during the manufacturing, installation, and use stage.
Our roofing systems come with a 20-year guarantee and have a life-expectancy of 50+ years.
They are Greenpeace’s recommended roofing membrane.
We also install full guttering and downpipes and encourage our customers to use water butts to retain and re-use water to irrigate their gardens.
We can also install a Sedum living roof as part of your garden room project. Sedum roofs are far more than just an eye-catching aesthetic option. They also generate several eco-friendly benefits:
- Natural wildlife habitat
- Prevents flooding – drains rainfall more slowly ensuring less pressure on local drainage
- Noise reduction
- Increased thermal insulation
We closely monitor our cladding and flooring supply chains to ensure they always align with our sustainability commitments. All our timber is premium quality and designed to last for the long life of our garden rooms.
When timber is sourced sustainably it is one of the most environmentally-friendly building materials available.
Our insulated garden rooms have the lowest U values of any similar design. This is due to the market-leading structural insulated panels (SIPs) we use. Our SIPs keep you and your family warmer in the winter, and cooler in the summer. Lower energy bills for you, and the lowest possible environmental impact.
Our aluminium doors and windows are environmentally A-rated, and significantly more sustainable, and effective, than similar uPVC options.
