This house in Zell am See connects its owners to their surroundings in a variety of ways. There is no one way of looking out, no one way of letting light in. Nature can be seen in every direction, and a sky-lit courtyard allows further light and oxygen to flow through. A light wooden structure wrapped in playful shutters houses the sleeping area above, with the master bedroom enjoying commanding views of the lake. Below, robust insulated concrete walls shelter the living areas. Glass doors let the outside in, and mosaics of perforations on the thick walls mimic the delicate openings of the shutters above.
