Nested in Québec’s Montcalm neighborhood, this renovation restores the home’s original residential purpose after years as an office. Dark turquoise walls enrich the living and dining areas, original hexagonal arches are preserved in natural wood, and a continuous banquette anchors the rooms. Rounded corners in walls, ceilings, and furniture guide movement. A wide staircase leads to the upper floor, while a spiral staircase ascends to a rooftop boudoir. Outdoors, a glazed opening connects to a terrace, pool, and intimate courtyard, extending the home’s inviting character.
