All of our garden room feature the same excellent levels of thermal performance achieved through the use of modern residential materials used in many newly built homes, as a result our garden building meet the required U -value required from the latest part L building regulations, ensuring a warm and comfortable environment in the winter with low ongoing energy costs and a cool enjoyable environment in the summer.

All of our structures follow best practice design standard for residential construction.  All structures utilise a treated timber residential specification sub floor with a ventilation gap created by our concrete plinth foundation system and we cover the whole site with a weed control fabric preventing any future vegetation growth.  The floor structure features 100 mm of polyurethane insulation with a U-value of 0.21 W/m2K against the Part L build regulations requirement of 0.25 W/m2K (a lower value is better and more insulative).

The walls are constructed from 120 mm Structural Insulated Panels (SIPs) known for their strength and thermal performance, they feature 100 mm of polyurethane insulation with a U-value of 0.21 W/m2K against the Part L build regulations requirement of 0.30 W/m2K.  The exterior of the walls are wrapped in a breathable and waterproof membrane which allows moisture to escape from the building but not to penetrate.  The exterior is finished in your choice of high quality cladding to provide the primary weather protection with a ventilation cavity behind.

All the windows and doors fitted are double glazed and meet the current building regulations requirements for glazing and feature locking systems that beat the current "secured by design" standards recommended by the UK police force.

The interior is finished with a traditional plasterboard, skim and paint finish, down lights, sockets and switches are brushed stainless steel, with a choice of flooring types and skirting available.  All our garden rooms feature a heater to suit the size of the structure with several designs available from functional to stylish.

The roof is an insulated and ventilated design, finished with an EPDM roofing system with a 20 year manufacturer’s guarantee.  The roof is insulated with 125 mm of polyurethane insulation and is mono pitched, meaning the roof has a fall for rain water drainage.  We follow the same designs standard for residential homes when designing the roof structure for your garden building.  The roof has a U-value of 0.17 W/m2K against the Part L build regulations requirement of 0.20 W/m2K.

All structural elements of your design are taken into consideration ensuring your garden building will resist the worst of the wind and snow loads the UK weather has to offer.  This ensures your garden build will stand the test of time and your investment will be protected and enjoyed for years to come.
