Located on Robert-Bourassa Boulevard, at the corner of Cathcart Street, this 33-storey concrete building accommodates 192 luxury condominiums. The project also includes 4 floors of underground parking (approximately 200 spaces), a sports centre with swimming pool, meeting rooms, a golf centre and a restaurant on 2 floors. It features environmentally friendly infrastructure (the use of water and heat recovery systems and energy-efficient insulation) as does phase 2, built in parallel, that covers 4,500 m2 on 8 floors of commercial and office space.

The structure is made of reinforced concrete. Some load transfers were carried out with post-tensioned beams. This project required very precise phasing due to the narrowness of the site and the high density of the surrounding environment.

For this project, NCK provided complete structural engineering consulting services.
