SoHo Champagne 2 faces its twin sister located on the neighbouring lot and stands among the tallest towers in Ottawa. With its 27 floors and four basements carved out of the rock, SoHo Champagne 2 contains luxury residences inspired by the lifestyle of a hotel. The building has a reinforced concrete structure composed of flat slabs resting on conventional type foundations.

Technical challenges :

• The proximity to the neighbouring SoHo Champagne Phase 1, required the development of a specific foundation strategy in order to avoid the transmission of forces to the existing foundations resting lower in the rock ;
• Several column translations were carried out in the first floors to match the tower's column grid with that of the underground floors, thus avoiding a redundancy of columns and transfer beams.  

Notable solutions and innovations :

• Design of a compact core to take up lateral forces due to earthquakes and wind through the use of diagonal reinforced coupling beams.
