Studio Gang’s first project in Canada, One Delisle is a new residential tower that considers how to sustainably grow cities. Located at an important node in Toronto and anchoring the corner of a full-block development, it provides much-needed density on a compact footprint, growing its neighborhood upward to meet urban challenges and benefit the city, while remaining sensitive to its context amid new open park space. 

Bringing an abundance of comfortable outdoor space to city living, the tower is tuned to Toronto’s climate and lifestyle. Its distinctive facade comprises a series of eight-story elements, which nest together as they spiral up the building. Balconies are set within these elements, with generous terraces set atop them. Leaning outward for sun-shading and wind protection, they permit use of the balconies and terraces well into the shoulder seasons. In addition to providing protected outdoor space, these elements lend the tower a more human scale. Their angled, alternating geometry allows for variously sized floor plates that result in unique conditions within the units, bringing a diversity of residential options to the mixed-use neighborhood.

Site Plan

Responsive to the surrounding streetscape, the tower is rectilinear at its base to fit within the city grid and address its corner condition at Yonge Street and Delisle Avenue, transforming into a multifaceted cylindrical shape as it rises to expand views, capture more sunlight, and minimize shadows on the street. The building’s setbacks allow for widened, landscaped sidewalks, which, in addition to new small-scale retail, create a pleasant pedestrian experience. Improving urban connectivity, the design also links the important node at Yonge Street and St. Clair Avenue with the newly developed Delisle Park.

Rooted in the existing architecture of the neighborhood, the proposed design retains elements of 1498 Yonge Street, preserving its main street character. Rendering by Norm Li.
