An articulated mixed-use residential building, with a 4-storey podium, mid-rise elements, and a 57-storey tower could soon anchor the corner of Yonge and Isabella streets in Downtown Toronto. Colliers Strategy & Consulting recently submitted a redevelopment proposal on behalf of YI Developments Limited that would bring retail and 606 residential units to the site.

The 0.2-hectare site is on the southeast corner of Yonge and Isabella, 300m south of Bloor. It is currently occupied by three low-rise commercial retail buildings, constructed between 1905 and 1923, with several interior and exterior renovations since. The existing buildings would be demolished.

A portion of the site (625-637 Yonge and 1-9 Isabella) was previously approved at the OMB to permit a 46-storey mixed-use residential building, totalling 27,200m². Since then, the owners have purchased the adjacent properties to the South (619-623 Yonge St), which provides for an opportunity to revisit the previous approval and provide for a new development proposal that optimizes the larger site area in accordance with recent amendments to the Provincial Policy Statement, Growth Plan, and Toronto Official Plan as well as the ever-evolving surrounding neighbourhood context.

Designed by Core Architects, the proposal is a sculpted, 57-storey, mostly residential mixed-use building, inclusive of a 4-storey base in keeping with street wall heights. The building has a total gross floor area of 49,248m², including 46,114m² of residential floor area, and 3,133m² of retail floor area, with an overall density of 20.2 FSI.

The entire Yonge Street frontage of floors 1 and 2 would be exclusively retail space. A small lobby residential entrance area is tucked away on Isabella Street, and servicing, parking and loading uses are accessed via Gloucester Lane.

On the 3rd floor, 305m² of amenity space forms an open-air courtyard, surrounded by 962m² of indoor amenity space. Residential units wrap the north and east frontages.

As illustrated above, at the 5th floor, a large outdoor amenity terrace is located atop the the base building facing Yonge Street, contiguous with indoor amenity space. Residential dwelling units are face east.

A series of step-backs as the building rises result in a highly-articulated built form as the eye travels upward, with floors forming a ‘u’, then an ‘L-shape, and then a linear element oriented north-south beginning at floor 37.

The proposal has a total of 606 dwelling units in a mix of: 50 studios (8%), 310 one-bedrooms (51%), 171 two-bedrooms (28%), and 75 three-bedroom (12%) units.

Four levels of underground parking provide space for 137 vehicles spaces (77 for residents, 60 for visitors/retail), and room for 606 bicycles.
