Site in Hertfordshire where Evolved Design managed the complete build from design through  planning and building regulations to providing a turnkey solution with project management on site.
The construction used the Porotherm clay blocks to provide a monolithic construction with external  wall insulation to give additional insulation and provide the ‘tea cosy’ effect to overcome thermal  bridges.
Triple glazed aluminium windows were installed within the thermal layer, again to avoid cold  bridges, and the insulation was taken down below the D.P.C level to prevent cold bridging at the  floor level.
Breathable, self cleaning render was applied to the ‘open’ expanded polystyrene insulation to give a  total wall U value of 0.16 W/m2K with a total wall thickness of just 315mm.
Excellent air tightness was achieved by using a direct plaster finish to the external walls & a whole  house ventilation with heat recovery system was installed and commissioned to provide a healthy  living environment and well as recovering energy back into the building.
