Formerly used to house railroad workers, a hundred-year-old Swiss dwelling has been reimagined as a modern mountain residence. Built in 1911, Maison ERG is situated in the Alps of Montreux. Although most of the interior has been completely renovated, the original iron and walnut staircase remains intact. Hallow grids inserted into the walls along the stairs transfer heat and light as well as provide a sly form of communication among residents. Custom concrete pieces along with minimal furnishings give the home an overall contemporary aesthetic while wood finishes offer a rustic warmth. Small timber openings frame is views of the surrounding peaks throughout the living spaces while sliding doors on the ground floor open out to an expansive garden terrace overlooking Lake Geneva and the Riviera.
