Garden room structure and materials

Backed by a 10-year manufacturers warranty

All our garden rooms are timber frame constructions, with rigid foam 50mm insulation which is covered by plasterboard and skimmed. A decorators mist coat of paint is then applied ready for the top-coat, which is available as an upgrade. This is all wrapped in a breather membrane which makes the garden room waterproof and then the cladding is applied.

The EPDM rubber roof has a 15-year guarantee and a life expectancy of more than 25 years. The roof is neatly finished off with our unique anthracite grey fascia that gently slopes to the back where the water runs off into the drainpipe and away from the garden. The entire structure sits on a steel framed floor with a vermin barrier that never rots.

*Custom or bespoke garden rooms have up-weighted C24 timbers and 75mm insulation that meets building regulation standards. These garden rooms are perfect for garden rooms that exceed 30sqm, or for customers that have a very specific design, style or shape in mind. They come with a Project Manager who oversees the installation and provides daily updates.

Solid Foundations:

Ensuring Stability and Sustainability for Your Garden Room

Our garden rooms come with concrete pile foundations as the standard option. These foundations are not only cost-effective but also environmentally friendly, as they utilise precisely calculated concrete holes, minimising waste. In larger projects, especially those subject to building regulations, we employ custom-designed concrete foundations crafted by experienced structural engineers. On occasion, we may opt for groundscrews when they are deemed the most suitable choice for the specific project. Your garden room will always be built on a foundation carefully chosen to ensure stability and longevity.
