Project size: 5,000 square feet

Program: The goal was to create a multi-unit, multi-generational housing prototype that recognizes the densification of Toronto’s urban fabric.

Location: A corner lot in Toronto's Chinatown

Solution: The structure places a grandparents’ suite below a single-family home. The massing of the house, based upon a multi-generational scenario, intentionally blends the units into a single whole that anchors its urban corner. The extended family shares a ground floor courtyard that connects to interior living spaces via sliding glass doors. Above grade, each family member has a private terrace.

Construction and materials: Recycled bricks—painted white—and red cedar panels compose the building’s façade.
