An introverted space, where exposed concrete and stereometric shapes create a dialogue with the territory. This is how the Haus der Kammern project by the Marte Marte studio presents itself. A house rooted like an autonomous mineral block along the grassy slope in the small community of Weiler in Austria. The whiteness of exposed concrete imposes itself on the verdant landscape in an architecture where the few other visible elements, such as the railings, tend to disappear in favor of the right angles and unaltered surfaces of the concrete house.

The only exposed volumes of the house,  the main one and a smaller one connected to the road, are joined below the hill's slope surface by a slightly labyrinthine path leading to the spiral staircase, the house's vertical connection, placed under a skylight. The staircase thus becomes a sculptural and sinuous core within the interior space, where an unexpected way of living is introduced. In contrast with the materiality of the outside, the inside is dominated by a warm and welcoming atmosphere, an enveloping room, where every surface is covered in solid oak.

The spaces thus build a large living area on one floor, from which two separate flights of stairs lead to the rooms on the upper floor. The interior is in constant connection to the surrounding landscape, thanks to large full-height windows, flooding the domestic space with light and opening onto large terraces, obtained by subtracting a quarter of the floor plan to each floor.

Haus der Kammern appears as a small fortress in the Austrian landscape, building its atmosphere of monumentality, but at the same time opening up from the inside with a view towards the massive Swiss Alps, almost aspiring to be their counterpart.
