237 Sherbourne Senior’s Residences Adaptive Re-Use

The renovation and expansion of 237 Sherbourne Street transforms a 19th-century duplex mansion into a thoughtfully designed seniors’ residence within TCHC’s William Dennison community.

The project delivers 11 one-bedroom rental suites and two shared amenity spaces, combining heritage character with contemporary upgrades. Original features—such as brick detailing and high ceilings—are complemented by a refreshed material palette to create warm, dignified living environments within a tight-knit urban setting.

Originally conceived as an interior retrofit, the scope evolved into a more comprehensive intervention, including an expansion and the redesign of the adjacent courtyard at 310 Dundas Street. The project required close collaboration with diverse stakeholders, including tenants, accessibility advocates, and construction teams, to ensure the design responds to community needs.

Situated within a Heritage Conservation District, the design carefully preserves the Sherbourne façade while integrating modern performance and accessibility standards. Barrier-free design is central, with gentle entrance slopes, generous landings, and equitable circulation routes.

Enhanced sustainability measures include a high-performance building envelope and a target air-tightness of 1.5 ACH. Individual VRF systems provide efficient climate control, improving comfort and indoor air quality while reducing environmental impact.
