located on the slope of linz's pöstlingberg, the 12 x 12 metre cube makes the most of the plot and moves as close to the north-eastern corner of the plot as building law allows. these two sides appear very closed, protecting against views from the neighbours higher up.
to the south and west, on the other hand, the house opens up with two all-glass façades. the west-facing front offers a magnificent view over the danube valley and catches the sunlight until late in the evening, while an external fabric curtain protects against too much sun and overheating.
the south façade recedes in a free form from the outer edges of the cube to form a covered terrace. directly next to it is a generous swimming pond. inside, the house develops from the open cooking / dining / living areas in the south-west towards the swimming pond, to the closed bedrooms in the north-east.
the house, which has no basement, is built from prefabricated, highly insulated wood-based panels. these were placed on the concrete floor slab by mobile crane in just a few hours. the inclined columns on the west façade brace the building. the roof slab, sloping slightly to the east, drains without gutters over the façade into a gravel-filled soakaway at the back of the house.
the cube is wrapped in plastic membranes: white epdm on the roof, and white teflon-coated pvc on the façade (invisibly welded to the roofing membrane). the membrane is fixed at points through the insulation between the timber structure and the membrane.
the simple form of the building and the high degree of prefabrication, together with very good cellulose insulation, condensing-boiler technology and external shading, make for a very economical and ecological building.
