Surrounded by forest and overlooking a lake in the south of Vienna, Austria, the House Birkensee is an amazing composition of volumes that flow smoothly from one to the other by the clever roof design. Labvert designed this vacation residence with a wooden deck as its foundation and, except for the walls of glazings separating the inside from the outside, the indoor-outdoor areas appear as continuous as the roofline itself. This play on volumes is an intricately woven pattern that has an ebb and flow to it as though it where a sculptural installation rather then a 3 bedroom home.
