House 1 is the first villa of the Aiguafreda community of 40 sustainable homes on the Costa Brava. Set on steep green hills near Begur directly overlooking the sea, this villa combines luxury with ecology. The house is built of wood and natural stone, its colours mixing naturally with the indigenous vegetation and the colour of the rock. The pool is a natural pool, with a basin of filtering plants and gravel doing the work normally done by chlorine or salt.
Its volumes are grouped in order to best adapt to the steep terrain, while making the most of the view. The living room overlooks the sea. The kitchen/dining room is south-oriented and overlooks the pool. Its facade can open completely to dissolve the boundary between inside and out. A roof overhang protects the interior from hot summer sun, while letting in lower winter sun to provide passive warmth. The bedrooms are dug into the mountain, thus staying cool, with their green roof forming an integral part of the garden. Natural ventilation and underfloor heating and cooling provide a comfortable climate throughout the year, with the green roofs providing unbeatable insulation.
