The Four Seasons project consists of two towers located in the heart of the Yorkville neighbourhood. The hotel occupies the bottom 20 levels of the 52-storey tower with the condo units located above a mid-mechanical level. A second residential tower is 27 storeys. There are five levels of underground parking.

Sway in both towers was kept to a minimum despite an open and virtually wall-free floor plate. The towers have prominent 27-foot penthouse level glass screens, providing the Toronto skyline with a new distinctive feature.
To accommodate a grand ballroom, fitness centre and pool, spa, banquet facilities and ground floor high-end retail stores, the nine-storey amenity facility connecting the two towers features 18 meter long spans. Conventional Warren trusses were nixed in favor of floor-to-floor height Vierendeel trusses to accommodate floor circulation and mechanical distribution. These long span trusses presented a design challenge due to their significant weight (weighing up to 65 tons). Trusses were preassembled in the shop due to a non-existent laydown area.
