Designer Ralph Germann inserted a partially glazed box into a 19th-century barn to form the main living space of Christine Bonvin’s home in Switzerland, which has been in her family for four generations. Soft light enters through original arrow-loop windows. Throughout the space, contrasting elements pay tribute to the spirit of the barn. The raw stone, visible through the interior’s glass walls, is tempered by the warmth of the century-old larch wood, which was salvaged from the original side wing and taken to a carpentry workshop in the mountains to dry before being reconfigured into furniture and kitchen fixtures.
