Award Winning Zero Carbon Home
Posted on 25th January 2012.
The three bedroom detached house plus studio which was completed in August 2010 cleverly makes use of a constricted, sloping site through split-level design and creates a series of interesting, unique spaces. A top lit vertical circulation volume floods the house with daylight and acts as the "lungs" by ventilating and cooling the spaces on warm days. Glazing to the south-facing rooms maximises passive solar gain, and a roof-integrated solar array provides electricity and hot water for the family, a biomass boiler covers the shortfalls in winter.
