Since UrbanToronto’s last update in January, 2025, construction at One Delisle in Toronto's Deer Park neighbourhood has progressed not only vertically, but with the first panels of its distinctive cladding system now having been installed. Designed for Slate Asset Management by Jeanne Gang of Studio Gang Architects with Toronto-based WZMH Architects as Architect of Record, the 44-storey condominium is rising at the southwest corner of Yonge Street and Delisle Avenue. As the tower climbs, its unique spiralling geometry, formed by rotating, receding floor plates, has become more pronounced.
Looking southeast from Delisle Avenue in March, 2025, construction had then reached approximately 14 storeys. On the west elevation, cladding installation is underway where dark-tinted glazing and black aluminum spandrel panels can be seen on the third floor framed by off-white panels; the newly installed curtain wall system hugs the northwest corner where the podium transitions to tower floor-plates.
Looking southwest in mid-April, 2025 when work to form the 17th storey was underway, this close-up of the north elevation shows to the left of the construction hoist cladding and glazing have been installed on the second level, while above, the rectilinear base begins to give way to the building’s signature spiral geometry. The staggered, notched floor plates are now beginning to rotate, creating a receding profile that begins to define the first eight-storey volumetric module, which will be further established by the facade materials once they are applied.
On the east elevation fronting Yonge Street, cladding is fully installed along the second floor. Construction hoarding and scaffolding frame the sidewalk at grade, while the concrete parapet above outlines the podium’s perimeter, where bronze metal accents and perforated screens will later be installed. Above, cantilevered balcony slabs rotate incrementally to form the fluted, sculptural massing.
Looking northwest across Yonge Street, this view highlights the angular geometry of the bright cladding, contrasted with dark-tinted glazing. The off-white panels are beginning to be installed in faceted, chamfered configurations — elongated hexagonal pockets that will define the stacked balcony slabs between deep recesses — that catch and reflect light at varying angles, with Gang having taken inspiration from hooded German beach chairs.
One Delisle will reach a final height of 155m and contain 371 residential units.
