Set at the city’s gateway along the main avenue, the building occupies a plot once taken up by a Chablais public-transport depot. A railway spur bisects the site as it swings into alignment with the town station, leaving a triangular footprint that the project exploits, extruding a five-sided mass that appears both poised and dynamic depending on the façade in view.
A central circulation core compresses the plan to a triangle, around which a ring of equally deep rooms unfolds. The triangle contracts further to form the void that flanks a straight-run stair. Rising six storeys, the building’s ground floor contains an office, a communal hall and archive rooms. The first and second floors are each let as single, open workplaces that can be partitioned with glass walls to create conference rooms or private offices.
The upper storeys accommodate five flats per level. The larger units anchor the corners, their living areas following the plan’s shifting geometry while the bedrooms remain orthogonal. An angular loggia at each corner differentiates dining and living zones.
The reinforced-concrete frame is left exposed—shear walls at the core, parapets, columns and slabs—while both the envelope and the internal closure elements are crafted from metal. The façade is a pleated skin of mirror-polished stainless steel, catching ever-changing reflections of its surroundings. Windows and doors are aluminium. In the office levels the core is clad in perforated sheet metal. Apartment finishes come in three palettes: green, blue or aubergine linoleum and tiles, with kitchen cabinetry in pink, sky or vanilla tones.
