Toronto House combines a 57-storey tower with the heritage-listed Southam Press Building, built in 1908. The redevelopment renovates and adds office space to the site, with the majority of the tower comprising rental units and hotels. The new building extends beside and over the existing 5.5-storey brick structure. To retain the visual integrity of the historic building, the two-storey addition above is recessed at the first floor, with the second floor extending to the edge of the façade below. A green roof atop this addition is an amenity for the tower. The street level is enlivened by a restaurant sidewalk patio, accessed through new windows and doors respectfully cut into the existing architecture.
