lausanne-based personeni raffaele schärer architects (PRS architects) have just shared with us images of their newest project in the suburb of chailly, an apartment building with six individual units. its strict adherence to the site boundaries and setback regulations informed the characteristic thin wedge forms at either end, while the other facades respond to the converging curves of the road to the northeast and the vuachere river to the west. the three storey reinforced concrete structure is clad in a roughcast metal coat that blends into the snow-covered landscape. each flat contains a unique floor plan and access to a private exterior garden, balcony, and terrace. a warm interior is highlighted with rustic wooden floors smooth plaster finishes on the walls, while the ceiling is left as exposed concrete, cutting down on excess material.
