A few months ago, the Triesch family moved into their house in Kleinmachnow in Brandenburg and not in the capital city Berlin. Some areas are still not quite finished, such as the sauna and the guest room in the basement - but a veritable Ray Kappe masterpiece has emerged, so skilfully placed as if it had been born from the Märkisch soil itself. It's a clean construction of concrete and wood that gently envelops rooms that flow into one another, and of abundant glass surfaces that mesh the inside with the outside. "I still can't believe we've come this far and that this is now our home," says Lars Triesch. "Ray Kappe's own house, built in 1967 for his family, was something like the holy grail for me. I said to him, 'We definitely need two children's rooms and a studio for my wife - otherwise you have free rein.'"
