Since UrbanToronto's last construction update article in May, 2025, cladding installation has begun at Concord Sky, where curtain wall glazing is now being applied above the retained facades of heritage buildings on the site. Designed by Kohn Pedersen Fox Associates with architects—Alliance as Architect of Record, and developed by Concord Adex, the mixed-use tower is rising at the southeast corner of Yonge and Gerrard streets in Downtown Toronto. Heritage preservation is being overseen by ERA Architects.
Looking southeast this month across Gerrard and Yonge streets, the curtain wall system, featuring reflective, floor-to-ceiling glass, has begun wrapping the podium levels above the retained facades of the Gerrard Building and Richard S. Williams Block. These heritage elements are being held aloft for by steel scaffolds, to be removed later in the construction process.
A materials diagram of the base and podium's western elevation indicates how the building's exterior will be composed upon completion.
A close-up of the northwest corner reveals early articulation of the tower’s cladding system. Installed glazing panels are arranged in a repeating vertical pattern: paired pains of reflective vision glass, often with an operable panel, are surmounted by perforated aluminum panels concealing vents and a band of reflective glass overing the slab edges. Between the windows, a section of exposed insulation will be covered by white-painted aluminum panels. Materials are staged on the floors above, draped in white tarp. At the base, Tyvek wrap shields the stone finial of the historic facade.
Coming even closer, a worker stands on the sixth floor, assisting with glazing system installation and alignment. This view reveals further details of the assembly, including the insulation boards fastened to the facade.
Seen from the east elevation along O'Keefe Lane, two levels of glazing are in the process of being installed above the extra-height ground level floors. Overhead, a cantilevered construction platform supported by scaffolding brackets projects beyond the slab edge.
When complete, the 85-storey tower will qualify, as counted by the Council on Tall Buildings and Urban Habitat (CTBUH), as one of Toronto’s ‘supertalls’, crossing the supertall threshold of 300m by 0.2m. While originally listed at 299m on the UrbanToronto database based on the standard practice of measuring from the building’s main entrance, the CTBUH measures from the site's lowest publicly accessible entrance, which on this sloping site is lower than the main entrance. By this metric, Concord Sky joins the ranks of Toronto’s 'supertall' buildings under construction.
Once complete, Concord Sky will deliver 1,407 condominium units.
