258 Christie represents the most distinctive massing strategy of the three Missing Middle projects. While the building is organized around the same prefabricated structural logic shared across the portfolio, it is adapted to its constrained site as a single-loaded corridor building wrapped around a central courtyard. This configuration allows the project to maximize access to natural light, air, and shared exterior space.
Located at the corner of Melville Avenue within an existing fabric of two- and three-storey storefront buildings, the site currently comprises four narrow 17-by-105-foot properties, each containing one residential apartment and one commercial unit. The new eight-storey, 56-unit building introduces significant new rental density while maintaining a compact footprint.
The building is organized around a vertical communal space created by reallocating area that would typically be devoted to private balconies. Units are arranged around the central courtyard and accessed by open-air, porch-like corridors. This configuration gives many units a dual aspect, providing opportunities for cross-ventilation, daylight from both ends of the plan, and a direct relationship to the shared exterior environment.
Entry to the building is marked by a narrow, tunnel-like passage carved through the ground-floor commercial frontage. The compressed entrance then opens into a concealed open-air courtyard, creating a distinct threshold between the street and the shared garden within.
From the courtyard, a central stair and open-air circulation system provide access to each rental unit while overlooking the planted landscape below. Vegetation climbs along perforated guardrails and through the building’s layered exterior spaces, transforming the circulation network into a series of immersive, garden-like communal rooms.

258 Christie is the second of three Missing Middle mid-rise, purpose-built rental buildings planned for Toronto. Conceived as a cohesive portfolio, the projects share the same DNA with common design principles, architectural details, and a distinct branded aesthetic.

There has been significant discussion and momentum around developing new housing models in Toronto, with recent by-law amendments focused largely on enabling gentle density at a smaller scale. Mid-rise housing, however, is not new to the city. For decades, buildings of this scale formed an important part of Toronto’s streets and neighbourhoods, combining meaningful density with architectural character and a strong relationship to their surroundings.
The mid-rise typology has been negatively complicated in the past decades by prescriptive municipal policies. These projects seek to revisit an earlier and more straightforward model of mid-rise housing, with approximately 60–76 units—comparable in scale to many successful apartment buildings constructed throughout Toronto more than fifty years ago.

This intermediate scale offers greater planning and by-law flexibility, allowing for streamlined massing and infrastructural simplicity. Reintroducing this scale provides a form of soft density that can integrate comfortably into established communities while supporting shared amenities and a greater sense of collective living.

All three buildings use a hybrid prefabricated mass-timber system of CLT floor panels, steel columns, and concrete cores. They are organized around a shared unit DNA, using the same three unit types with consistent dimensions and layouts across the portfolio. Although each site has a distinct urban context, this modular framework maintains efficiency while allowing each building to respond specifically to its surroundings.
The façades follow a similar prefabricated modular panel approach, simplifying and accelerating construction while allowing each project to develop an architectural expression suited to its context.
