Quadrangle and Herzog & de Meuron design 87-storey mixed-use tower

Quadrangle and Swiss-based architectural firm Herzog & de Meuron have been appointed by Kroonenberg Groep and ProWinko to design a mixed-use tower at the northwest corner of Bay and Bloor.

“This is an iconic block in the neighbourhood and Toronto at large. We have an opportunity to deliver a project that sets a new benchmark for design and strives to give something back to the city,” says Lesley Bamberger, owner of Kroonenberg Groep.

With a 3:1 ratio in the north-south orientation, a simple extrusion of the site footprint rises 87 storeys. A linear core at the western façade is proposed which maximizes the usable area of the floorplate, the aspect over Bay Street to the east, and simultaneously provides privacy from any adjacent development to the west.

The first 16 floors will replace the existing retail, office and technical functions. A private amenities level will separate these functions from the condominiums above, and a large restaurant, sky lounge and rentable spaces occupy the highest three floors of the building.

The proposal is a layered expression of the vertical structural elements, interior glazing (thermal envelope), exterior timber roller shades and an outer layer of transparent, open-jointed glass.

The effect is a building, which at times appears transparent and expressive –revealing the scale and activity within the building; and at other times, the reflective outer layer of glass emphasizes its dramatic proportion.

At street level, residents enter a triple-height lobby from Bloor Street and take one of four dedicated lifts to their condo level. Residences will range from one bedroom, to multi-level penthouses, totalling 332 condominium units spread over 64 floors.

The tower marks Herzog & de Meuron’s first design in Toronto, with Quadrangle serving as project architect and Urban Strategies rounding out the design team.
