Forming of Rosehill Tower in Toronto’s Deer Park neighbourhood has passed the halfway mark, on its way to 31 storeys just off Yonge Street south of St Clair. Designed by Hariri Pontarini Architects for QuadReal Property Group, BGO, and bcIMC, the infill development on a ‘Tower-in-the-Park’ site is just a short walk from St Clair subway station. UrbanToronto last covered the site in April, 2023, when excavation and shoring were just getting underway.
In early 2024, the development team sought a minor variance to increase the building height to 35 storeys and raise the unit count from 263 to 299. However, the Committee of Adjustment refused the variances, and the appeal period has since lapsed.
Looking southeast in April, 2024, the crane, installed that January, rises near the east side. At the base, concrete walls are formed for the lower of the two underground garage levels, with rebar projecting skywards in preparation for P1 work. At the back of the photo, the P1 and ground slab — supported by a grid of shoring posts— await the new construction. Behind the crane, the single-storey amenity pavilion is taking shape, with sections of blue weatherproofing along the roofline.
The structure emerged above grade later that summer. Seen from a high-angle view in October, 2024, it stands at two storeys with the third partially formed at the south end. The west elevation reveals step-backs at the second and third levels for future green roof and terrace space. Third-floor formwork and concrete walls are seen around the crane, while sub-grade work remains active along the north and east perimeters, blocked off by temporary fencing.
Viewed from the northeast early this month, Rosehill Tower has reached the 18th floor. Cladding and glazing installation have progressed up to the eighth floor along the east elevation, while temporary wooden boards mark areas awaiting window wall installation. A column of balcony slabs projects at the northeast corner, supported by shoring posts as the concrete continues to cure. The tower’s chamfered southeast corner is now legible to the left, as the facade pivots with more projecting balconies. Behind the scaffolding, an angled third-storey slab supported by cylindrical concrete columns cantilevers over the sidewalk to accommodate a future outdoor terrace amenity.
This view of the north elevation shows the window wall system, defined by charcoal-toned mullions and spandrel panels, framed by bands of white accent cladding. Cementitious panels at the base and along the west edge will continue along the east side to create a border. The construction hoist rises along the northwest corner.
This southeast-facing view shows the west elevation, where cladding now mostly covers up to the ninth floor. Projecting balcony slabs extend in three vertical stacks at either end and the centre. Below, glazing and spandrel are in place on the third floor and partially installed along the second. The cantilevered slabs at the first and second floors are set to be canopies finished in charcoal metal fascia and a walnut-toned metal plank soffit system.
The tower forming work is proceeding to 31 storeys, and a height of 103.5m.
