The Vogels’ residence in Sattel, Schwyz, is located 1,100 metres above sea-level, in the Mostelberg skiing and hiking region. The site grants a wonderful view of the surrounding mountains and the Lake of Aegri in the distance. As the plot shows a slight dip, not much of this panorama can be seen close to the ground. The basic concept of the building was however developed out of this seeming disadvantage: both the residential part of the house and the part dedicated to work are raised above ground level and rest on an unheated basement, which only houses the garage and the basement. And because the building code only allowed a two-storey structure, the house expands horizontally. This led to its characteristic projections and embeds it in a simple way into the irregular terrain. The living area is accessed via an outside staircase underneath the western projection and leading to an entrance courtyard that also acts as a sheltered terrace. Placing the vertical access outside the core volume helped avoid a commingling of heated and unheated spaces. Thus, the insulation perimeter is precisely defined and designed along simple lines – something quite essential to realize the passive-house standard (Minergie-P). The chosen mixed construction composed of massive, locally manufactured construction elements and light prefabricated ones efficiently combines the advantages of both materials. The core made of raw concrete (ceilings and floor) and sand-lime plasterwork (walls) is used to obtain thermal mass, while the timber structure enables thermally highly insulated elements, whose thickness was used to improve the statics. In the present case, the 42 cm thick roof panels allow a column-free bridging of the 10 m wide living room. Besides, they also rest on the two longitudinal elevations that act as slabs and between which the other façade elements as well as, at freely arranged heights, the floors of the projections are spanned. In its entirety, the timber structure is put like a hat over the solid, almost three-storey high spatial sculpture. Part of the edges use the basement as a support, while the remainder projects due to the shear walls of the longitudinal elevations. This discloses a major strength of the system developed by Pius Schuler AG based in Rothenthurm/SZ: the inner, unclad block-wood board with its thickness of 35 mm boasts excellent values of longitudinal bracing. This allows a longitudinal elevation of façade-high elements wide as a truck even in the area of the overhangs. Inside, the silver-painted plaster with its subtle traces of working meets the unaltered but stylish block-wood panels made from larch wood. Outside, darkly varnished panelling envelopes the timber structure shaped to appear as a single roof and whose design is to recall the neighbouring buildings erected in the early 1970s. The roof surface itself is fully covered with photo-voltaic and solar thermal elements and will cause the energy yield to be larger than the energy consumption. An energy-plus building.
