This concrete house on stilts is a family home in Austria by Vienna studio Wolfgang Tschapeller Architekt.

Called Single Family House St Joseph, the exposed concrete structure features irregular-shaped windows and sits on four supporting legs.

A shallow pit has been dug underneath the hovering building and can be utilised as a car port or storage space.

Despite the flat planes of the exterior shell, the interior space features a series of faceted walls, forming oddly-shaped rooms and windows.

The interior spaces are finished completely in white, with the exception of wooden flooring in some rooms and the treads of the staircase, which cantilever out of the wall.

The concrete form is set on 4 supports – one one-legged element, two two-legged elements and one three-legged element.

Its distance from the ground ranges from 120 cm to 210 cm.

A second form, soft, white and independent of the outer shell, is set within the concrete shell.

The white form opens up and programs – makes habitable, if you wish – the concrete shell’s inner area, which is 2165 cm long and approx. 515 cm high.
