Toronto will soon be home to a new architectural landmark, One Delisle – the first residential building in Canada designed by visionary architect, Jeanne Gang, Founder and Partner of Studio Gang. Gang was the only architect named as one of TIME Magazine’s 100 most influential people in 2019. She is a MacArthur Fellow and a leading advocate for gender equality in the fields of architecture and design. With offices in Chicago, New York, San Francisco, and Paris, Studio Gang is responsible for some of the world’s most diverse and compelling buildings and spaces.

Each residence includes custom interior design by Studio Gang, elevating the design experience in Toronto’s luxury market. Yonge and St. Clair is rich in history and home to some of Toronto’s most luxurious residences, renowned schools, shops and restaurants, and green spaces like the recently upgraded David A. Balfour Park, forested trails, ravines, and Toronto’s oldest reservoir. Yonge and St. Clair is a place of significance to Toronto and will soon be one of its most distinctive.

One Delisle is a vision for the future of high-rise living. The residential tower marries environmental and civic needs with architectural ingenuity. For this project, Studio Gang has considered how to sustainably grow cities without compromising on design. The dynamic form of One Delisle provides much needed residential density on a compact footprint and  complements the surrounding neighbourhood. Rising from a square base at street level, One Delisle spirals to become a 16-sided circular tower with generous outdoor spaces throughout the building.

The building’s terraces and balconies unite the energy of Toronto with the calm of the surrounding natural landscape and ravines. Studio Gang was drawn to these opposing elements and has brought them together at One  Delisle, where natural and organic elements are contrasted with bold urban finishes. The residential building does not merge with the neighbourhood, it embraces it.

The Project: 47 Story tower featuring a collection of 1 Bedroom, 1 Bedroom+ Den, 2 Bedroom, 2 Bedroom+ Den, 3 Bedroom and Penthouses suites. The building is divided into three enviable trenches:

The City Collection: Floors 5 to 29

The Penthouse Collection: Floors 45 to 47
