For the client, it was imperative that the program of the 200,000-square-foot building support SRIC’s hoped-for spirit of collaboration between university entities such as the Entrepreneurship program and Innovations and Partnerships Office, and private-sector building occupants like the Vector Institute for Artificial Intelligence and other startups and corporate partners. The response to that design brief is apparent upon setting foot, from either the west or south-facing elevations, in SRIC’s inviting and partly double-height oak-paneled lobby. Two stairwells, to the east and west, provide access to a balcony overlooking the lobby as well as to the second level, which hosts event-related spaces such as a chapel-like multipurpose hall, replete with chevron-shaped ceiling acoustical baffles, breakout rooms, and a catering kitchen.

Along the facades of the building, the large expanses of glazing offer substantial daylight and views and play a central role in fostering cooperative use of spaces within. Occupants decamp from elevator banks into capacious hallways that have become de facto spaces for lingering and conversation because of their well-lit airiness. The primary circulation stairwell, positioned on the west elevation and glazed from base to summit, offers an uplifting, rather than tedious, vertical trek.

But it is the communal spaces located on the seventh and 10th floors—the design team refers to them as “winter gardens”—that serve as the primary spheres for gathering. There, the wood-paneled double-height spaces, coupled with their terraces, present engrossing views of Toronto’s cityscape. Both can also be accessed by stairwell from the floor above, and conference rooms on those two levels, with generous windows overlooking the communal spaces, deliver ample opportunities for people-watching. Outside the communal spaces, SRIC’s tenants occupy and share a mix of loftlike and minimally detailed class- and meeting rooms, offices, and curated startup incubator spaces.

Developing the building envelope’s precast concrete unitized curtain wall panels that clad the poured-in-place concrete structure proved an iterative and challenging process. The design team and the manufacturer created and reviewed numerous models, such as a terrazzo prototype, before opting for a sandblasted finish like granite, chiefly as a nod to nearby masonry buildings such as the Mathers & Haldenby–designed Modernist stone-clad Ministry of Finance (1966). At first glance, the panels—which have origami-like folds and span nearly 14 feet from floor to floor—appear nearly uniform, but achieving that effect across the building’s tapered volumes required a novel fabrication approach.

“We spent about a month on the technical side alone, developing a way to detail and manufacture the panels, because, as you move up the building, the width of the vertical precast concrete narrows between the window units, and resolving their angled folds requires a slight torque in their face geometry,” explains Teeple Architects principal Wes Wilson. To address that quandary, the design team and the manufacturer created 3D computer models for some 300 pieces of formwork, which were then fabricated using a CNC machine. Those hundreds of plywood elements were pinned together rather than nailed, to facilitate their reuse for the manufacture of nearly 900 precast-concrete panels. Each is fitted with an integral drip system, which will help to prevent the buildup of grime across the facade.

Although the start date for the second phase of construction, which will add 400,000 square feet to SRIC, is yet to be announced, the design team did factor the expansion into this first phase of the project: at the ground floor, a portion of the eastern elevation will be demolished to make way for a continuous block-long lobby. And, in the basement, knockout panel walls can be removed at a later
date should the city, and SRIC, wish to pursue an expansion of the adjacent Queen’s Park subway concourse, with direct access to the Innovation Campus. “It really is part of this urban edge, between the University of Toronto and the city,” says Manfredi. “And our hope is that SRIC will serve as a landmark and sentinel within that environment.”
