Haller Jürgen together with Peter Plattner designed the House Haller in Mellau, Austria. The entire design of this compact house conforms to the location and it was built into the slight decline. As the hill side of the house is embedded, the east facing cellar area could be naturally illuminated and used as an office, for example. This office has direct access, via covered outdoor steps between the main entrance and the carport. Due to its ideal positioning, the building profits from the optimal use of the mountain sunshine. The internal walls and ceilings are covered with local silver fir wood, which gives the rooms a cozy feeling despite the large glass windows. The outside façade and the roof have been finished with local silver fir shingles. Here we can see how the architect as made use of a single material, testing its possibilities and confinements. What was once considered confined to traditional buildings appears here as experimental.
