This project involves the construction of a mixed-use complex (residential and commercial) located in Montreal’s Griffintown neighborhood, at the corner of Peel and Wellington.

The building is composed of a two storey podium from which emerge the two point towers with 462 residential units in total. The project forms a complex of 24 storeys above ground (70 m / 230 ft) as well as three levels of underground parking.

The project is particularly characterized by large 5 m (16 ft) high commercial spaces, a vegetated inner courtyard, two green roofs on the podium, a rooftop pool on the tower parallel to Shannon Street and a reflecting pool on the roof of the other tower.


  • Twin towers on a common podium requiring multiple lateral analysis models in order to understand the impact of different phasing possibilities when an earthquake occurs.
  • Foundations were optimized by trying different foundation systems to account for poor soil conditions and verifying the feasibility and cost of the different options.
  • Mixed-use podium levels with complicated column transfers.
  • Extensive landscaped roofs at podium levels and diverse rooftop amenities at the top of the towers (pools for example) required straightforward structural solutions to manage the architectural complexities.


  • Value-engineered mixed deep foundation system using both large diameter augered caissons and driven steel piles. 
  • Complex suspended structures such as a rainwater storage tank and a ground-floor level Hydro vault were integrated.
