BDP Quadrangle has revealed the design of a 54-storey, mixed-use tower in downtown Toronto, Canada. The project will replace an existing 10-storey office tower built in the 1960s. The new tower will contain office and residential units, with amenities and outdoor terraces on the 11th floor and at the ground floor. The building is planned to accommodate a total of 278 apartments with penthouses on the 52nd and 53rd floors. The project is currently in the pre-construction phase.
