The high-rise buildings will be located on Alberni Street in Vancouver's West End neighborhood.
Renderings show two irregular-shaped towers studded with angled balconies that form a bottleneck towards the base and then open up to a shared podium.
Renderings show balconies, terraces, and niches spilling over with plants. Heatherwick Studio has recently focused on biophilic design, with projects including a Maggie's Centre in the UK and a skyscraper in Singapore with plant-filled balconies.
The proposal estimates the project will include 401 homes, a childcare facility, and enough parking space for over 500 bicycles.
At 105 and 117 meters tall, the project represents the first high-rise project in Canada for the practice.
