HOK’s sustainable design for this 21-story condominium tower is focused on the development company’s triple bottom line: people, planet and profit.

Designed for LEED Platinum certification, the development offers 140 condominiums with spectacular views of the Ottawa River, Gatineau Park and Sparks Street. Residents will enjoy urban vibrancy in a green setting.

The site is next to Ottawa’s historic Christ Church Cathedral. This development will give the Anglican Diocese of Ottawa a new revenue stream.

HOK, Windmill Development and Andrea Kantelberg Designs are collaborating on the design that provides environmental, economic and social benefits.
