Located near the lakeside promenade at St. Moritz Bad, the Chavalus building project closes a gap site. While the façade along Via dal Bagn is clearly spatially defined, to the rear the building opens onto an outdoor area, with distant views of the picturesque mountain landscape. The choice of materials and colours refer to regional building culture and are reminiscent of grand hotels from the turn of the century. The ground floor is clad with travertine and the form of the roof cornice invokes the houses in a classicistic style that were built after the fires in Zernez and Lavin. Based on a historic spray plastering technique used on typical Graubünden houses in the early 20th century, a coarse-grained façade plaster was applied. The windows borrow features from the funnel-shaped windows of old Engadine houses. The residential structure of the quarter is reflected in the building project: private and rental flats, flats for senior citizens, as well as communal facilities, shops and gastronomic establishments have merged together.
The flats for senior citizens extend from façade to façade. Towards the street there are kitchens and dining areas, while the bedrooms and living rooms face the quiet open area. The bedrooms have verandas in front, which are braced with wood like traditional Engadine pergolas.
The compact form of the building ensures no unnecessary loss of heat. Triple-glazed windows provide excellent insulation and contribute significantly to positive energy ratings.
