This striking extension clad in stained Western Red Cedar was voted the Grand Designs ‘Extension of the Year’ in 2009. Its winning lines reflect the passion of a client committed to achieving something beautiful and striking. Greenheart supported their vision with both design input and careful construction needed for a thermally efficient, air and weather-tight envelope.

A conventional timber frame sits on masonry walls, with timber I beams for floor and roof construction. Hunton Bitroc, with its good thermal insulation, and highly breathable Sarket were used to sheath the frame. Wind and water-tight, they deliver high levels of thermal efficiency.  Recycled paper was used for additional insulation. The extension has high performance Aluminium windows and bespoke Douglas Fir shutters and doors.
