Located in the small, unspoilt cove at Crackington Haven, Grey Roofs replaced a structurally unsound 1920s bungalow which was visually detrimental to the village and surrounding AONB. Set on the side of a steep valley, the new five bedroom dwelling fits discreetly into its coastal context and provides a modern home with high levels of energy efficiency. The design concept is of a simple, heavy stone plinth built into the hillside for the partially underground lower storey, with the upper storey comprising of a lightweight timber frame. Large areas of floor to ceiling glazing give dramatic views westwards along the valley to the cove and the sea beyond. The basic form is traditional, with a pitched roof and natural materials such as slate, timber, render and stone, but interpreted and detailed in a contemporary manner. Solar thermal panels and air source heat pumps optimise sustainable energy solutions for the property. Removal of ad hoc ancillary sheds and the construction of a replacement garage completed the project.
