7 St. Thomas

Toronto, ON

St. Thomas harmonizes retail and commercial design through an inventive interplay of form and light, blending Victorian and contemporary materials to create a unified work. Six heritage townhouses are integrated into a three-storey podium, with a sinuous six-storey tower above. The podium wraps around and incorporates the heritage buildings, matching them in scale and proportion, using glass and stone to contrast and enhance the existing façades. The development houses retail at ground level and condominium office spaces throughout, blending high design, ecological responsibility, and civic enhancement.

The building peels back from the neighbouring context to preserve the light and views of existing residential buildings. Located around the corner from the busy Bay/Bloor intersection, the design was born from a desire to seamlessly integrate into the existing fabric of the neighbourhood and to contribute to the urban environment. Capitalizing on its position in the midst of a growing residential neighbourhood and its close proximity to multiple transit lines, 7 St. Thomas is a functionally integrated development and model for urban sustainability.

A piazza-like square at the corner of St. Thomas and along Sultan Street forms a public amenity within this densely built area.

Physical Model Study

The nine-storey building contributes to the urban environment through various features, including a high-performance curtain wall with a ceramic frit that reduces thermal transmission; large-capacity rain cisterns that feed back into the building’s greywater system; and water-efficient green roof terraces on the third and ninth floors.

The curved white glass curtain wall provides unobstructed views from the upper levels. A ceramic frit minimizes solar heat gain, while the glass is designed to retain heat in winter, reducing both cooling and heating costs.

The tower is wrapped in fritted glass and undulates in response to the existing fabric of the site, allowing for light penetration. The contrast between the solidity of the red brick heritage houses below and the translucent permeability of the glass tower—which steps back and floats above the Victorian frontages—highlights both typologies.
