Toronto House

19 Duncan Street, Toronto

Toronto House combines a new rental tower with a century-old heritage building to create a modern mixed-use development that has become the Canadian headquarters of Thomson Reuters. This development combines a residential rental tower with Class A office space above a multi-level parking garage and health club.

Due to numerous constraints, the façade was undermined and suspended above the excavation for the below grade parking. This required post-tensioned steel framing for both the façade support and the foundations anchoring the steel framing. The preserved façade now surrounds the Thomson Reuters office, with the former roof now a landscaped terrace for the office tenants.

The tower’s structure features a central elevator core and columns for the rest of the floorplate. Providing columns rather than walls allowed for flexible space to accommodate future changes in the rental market.
