Program: The clients wanted the house—which is situated on a ravine near the city center—to have a strong connection between indoor and outdoor spaces, and to encompass a modernist sensibility, with every space and site line being fully considered.
Location: Toronto, Ontario, Canada

Solution: A stipulation of a 1950s-era zoning law required a setback from the top of the ravine, in turn influencing the house’s shape, which takes the form of three stacked volumes. Each of the house’s levels shifts in response to its own set of criteria: zoning, views both into and out of the house, daylight, and structural design. The site offered opportunities for expansive glazing to the rear without concerns for privacy and quiet. This allowed for protected outdoor spaces, including a terrace to the west of the middle volume, which provides a covered space for outdoor cooking and dining. In accordance with site constraints specifying a compact footprint for the lower floor, main living spaces were placed in the middle volume and cantilevered to the rear, with views directly to the treetops.
Construction and materials: Concrete was selected for its durability, strength, and potential for vertical and horizontal application, as well as for its aesthetic. The architect employed a building system of cast-in-place concrete sandwich panels: the inner layer of concrete is structural, the outer one forms the cladding. Between the two is a continuous layer of extruded polystyrene insulation. With the concrete left exposed on both sides, this construction method allowed the exterior cladding, insulation, vapor barrier, structure, and interior wall finishes to be completed in a single casting.
Completion date: January 2015
