This high-rise is 51 stories tall and has a 5-level underground parking facility with space for 1,100 vehicles. The total surface area measures 153,300 m2.

It includes an atrium with an indoor skating rink, an integrated amphitheatre and restaurants.  The Montreal South Shore Transit (STRSM) system's intermodal terminal offers its passengers inside access to the buses as well as a direct indoor connection to Montreal's subway system.

The structure, originally designed to be of concrete, was modified to a hybrid "concrete core - steel structure".  This was the first time that this new technique had been used in Quebec and it cut 6 months off the original schedule.

Despite the fact that a section of Peel Street caved in right at the beginning of the project because a municipal water main ruptured, the extremely tight schedule was met.

Strict coordination of the delivery of materials, pedestrian and vehicular traffic, temporary accesses to parking, the neighbouring Château Champlain and Bonaventure Hotels, the Bonaventure subway station, etc.

The STRSM bus terminal, located in the building's basement, was delivered prior to the completion of the rest of the structure and this necessitated creative traffic, security and logistics management.

The most avant-garde characteristics of this building are:

  • Integrated security system managed from a central control station.
  • Controlled-volume air induction system.
  • Air quality control system on each floor and temperature control system at each window.
  • Long-boom window washing system, unique in North America.
  • 22 high-speed elevators, 2 service elevators, 4 elevators for the parking garage and 8 escalators in the atrium.
