Waterloo’s third-year winter studio has always been an opportunity to explore the relationship between architecture and the city. The 2020 studio—“Our House is on Fire”— focuses on the intersection between two contemporary crises: the climate emergency and Toronto’s housing emergency. The challenge of the studio was to design a series of deeply affordable apartment buildings on City-owned and currently vacant sites along Sherbourne Street in the center of Toronto’s Downtown East. Each building was required to integrate complementary public programs at grade that would provide a network of support for low-income residents and form a single community land trust that would secure their affordability in the future.
