Anybody who thinks that it is not possible to live, energy efficiently, in an old concealed workshop will be shown otherwise. It was important for the client to integrate his electrical sports car in the design and he asked us to introduce a large amount of daylight. Our aim was to keep the industrial nature of the building and introduce an outdoor space that would spread daylight and fresh air into the loft. The workshop could not be equipped with fašade windows because it is flanked on all sides. by a late 19th-century factory building. Studio OxL transformed this former carpenter?s workshop into an energy efficient home loft by introducing a big patio with double layered glass, a heat pump and floor heating throughout the whole space. The design respects the old industrial doors and building structure, but isolates the inside from the rest of the building.
