T3 Sterling Road

Toronto, ON

T3 Sterling Road is a landmark development in Toronto’s Junction Triangle, bringing sustainable, timber-based construction to the heart of this vibrant neighborhood. Designed as a creative office campus, the project offers three buildings with 415,000 square feet of flexible workspaces, curated amenities, and robust transit connectivity. Emphasizing timber, talent, and technology, the development highlights Toronto’s emerging role in sustainable and forward-looking office design.

Consisting of one 6-storey and one 8-storey building, the mass timber portion of the campus reaches heights of 130 ft (40m) across 310,000 sf. of timber office and amenity spaces. The structure uses dowel laminated timber floors and roofs, supported by glulam post and beam framing. Steel brace frames act as the lateral system. To meet the design requirements for the 8-storey building, both the DLT and glulam achieved a 2hr FRR. Although the design's 8 storeys rose above the local code limit at the time of construction, the design team submitted an Alternate Solutions Report to the City of Toronto to allow exposed timber nearly everywhere in the development.

T3 Sterling Road’s design is tailored to the modern workforce, offering rooftop terraces, a club-quality fitness center, and collaborative workspaces that enhance tenant experience. Floor-to-ceiling windows maximize natural light, while dedicated bike storage, end-of-trip facilities, and high-speed transit access further support an eco-conscious lifestyle. With LEED and WELL certifications, the development is optimized for sustainability and wellness, setting a new standard for office spaces in Toronto.
