199 College Street is a visionary mixed-use residential tower that marks a new chapter in Toronto’s architectural evolution. Designed by 17|21 Architects, the 45-storey (155 m) building introduces a refined contemporary expression while respectfully integrating the restored heritage façades of 191–199 College and 74–76 Henry Street.
With a 775 m² floor plate, the tower delivers a diverse mix of rental and affordable housing, complemented by street-level retail and publicly accessible spaces that activate the College Street frontage. The slender massing, articulated podium, and elegant façade treatment of glass, metal, and masonry establish a sophisticated dialogue between historic context and modern design.
Sustainable systems, energy-efficient envelopes, and enhanced public realm improvements reinforce the project’s commitment to livability and environmental performance. 199 College Street stands as an inclusive, design-driven landmark—celebrating Toronto’s layered heritage while shaping the city’s next generation of vertical urban communities.

199 College Street features a reinforced concrete structural system founded on deep caisson foundations socketed into bedrock to support the 45-storey tower. The concrete frame, comprising shear walls, columns, and flat slabs, provides strength, stiffness, and flexibility for varied residential layouts. Along College Street, the heritage façades are being carefully retained and structurally integrated into the new podium. Temporary steel bracing stabilizes the masonry during excavation, followed by permanent ties connecting it to the new concrete structure. This approach balances the demands of a modern high-rise with the preservation of Toronto’s historic fabric, uniting engineering precision with architectural heritage.
