Bespoke Garden Rooms Design & Construction

All bespoke garden rooms from UK Garden Room are designed & constructed to the latest building regulations standards incorporating the code for sustainable homes.  In the first instance we custom design new bespoke garden rooms on our proprietary software where we produce budget costs, plans and 3D images.

We then send the information to our architect for full drawings, structural calculations and material cutting lists.  This ensures your new garden building will be structural sound and comply with modern building regulations.  UK Garden Rooms are built for year round use and carry a high EPC energy rating.  Our EEfit building system comprises structural insulated panels for strength, longevity, air tightness and to eliminate cold bridging associated with many timber frame buildings keeping you comfortable in summer or winter.

We commit to providing  eco-friendly buildings which are further enhanced by use of ground screw pile foundations eliminating waste which means less vehicle trips because we don’t need skips or concrete.

Foundations, Base and Floor

Ground Screw pile foundations support a 100mm base frame which in turn carries a 100mm thick interlocking structural insulated panel (SIP) above the ground protected by a vapour barrier ensuring a free flow of air under the building, eliminating the risk of rising damp, and condensation.  Floor covered with engineered wood panels with a choice of colours.
