Casa Tuja, the house of Hans Grelling, created by Richard Neutra in 1961-3. Situated at the fot of Monte Verità, overlooking lake Maggiore. Does it get better than this? Me thinks not.
Upper floor as pictured below; first floor contains the garage, a guest room and another living room, or gillestuga as we say in sweeeden.
Another modern interpretation of the alpine chalet here.
