405 Sherbourne Toronto
A dual-peaked tower proposing that social housing can be genuinely generous, in form and in life.
This project begins from a simple conviction: social rental housing can carry architectural ambition without apology. Rather than answering Toronto’s affordability crisis through minimum provision, the project asks what collective dwelling can genuinely offer in scale, in the generosity of family-sized homes, and in the quality of shared life. This is a building designed for families: homes large enough to grow into, oriented to light from two directions, set within a new neighbourhood green that supports a full life at any age.
The site occupies a surface car park threading between Sherbourne and Bleecker streets, already used as an informal neighbourhood shortcut. To the east, Cabbagetown’s low-rise terraces of red brick, bay windows, and pitched rooflines; to the west, a corridor of towers pressing northward along Sherbourne. The building sits precisely at this threshold and must address both: the intimate domestic grain behind and the civic scale of the avenue in front. Its facade takes its cue from Cabbagetown’s material culture, not through imitation but through a shared commitment to mass, depth, and permanence. This is a building that intends to belong, and to last.
Two conjoined volumes, peaking at 26 and 35 storeys, rise from a compact two-storey podium. The double silhouette choreographs the building’s section: the upper tower tapers above the lower peak, reducing its presence against the neighbourhood grain behind while gathering generous floor area below. Floor plates are sized for true family homes, two- and three-bedroom apartments with the depth to support dual aspect layouts, drawing daylight from two directions and breathing across the building’s full width.
At ground, the project stitches together what the car park divided. A new green pedestrian passage, sheltered, planted, with tree canopy and soft surface underfoot, unfolds through the block from Sherbourne to Bleecker, where it opens into a new public picket park: a characterful urban room edged with planted enclosure that echoes the domestic rhythm of the surrounding terraces. Community and amenity space anchors the base of the podium, spilling into the passage and animating the ground plane. Outdoor resident terraces gather above. Light passes between the volumes, and the lower mass addresses Carlton’s human scale while the taller peak asserts itself at the scale of Sherbourne’s emerging skyline.
A facade of solidity and depth, with thick reveals, robust material edges, and considered fenestration, is designed for Toronto’s full four-season range, providing thermal mass and a permanence of character that glass-curtain construction cannot offer. The project is designed to meet the Toronto Green Standard (TGS): thermal performance and reduced operational carbon are embedded in the envelope strategy from the outset, with the building’s compactness and orientation reducing baseline energy demand before mechanical systems enter the picture.
Urban greening and biodiversity extend across every scale: the Bleecker picket park, the planted passage, and the outdoor terraces collectively replace an entirely hardstanding block with native planting, canopy trees, and biodiverse ground cover that supports pollinators and extends the neighbourhood’s green network. Parking is reduced from 59 spaces to 13, freeing the structure from unnecessary excavation and redirecting resource toward living quality above, while 331 bicycle spaces signal a different kind of urban life.
Building on Alison’s social housing work in London, 405 Sherbourne puts a proposition to Toronto: that public rental housing can hold its own, architecturally, spatially, and ecologically, against any building. It advances a more generous idea of what the city owes its residents, and tests whether excellence in social housing might be the most civic architectural act of all.
