Project Overview
This project consisted of the pre-conceptual design and 3D massing study for a new residential building located on Henri-Bourassa Boulevard East in Montreal. The study specifically aimed to adjust the building height so it would match the existing development on the opposite side of Millen Avenue (609 Henri-Bourassa East), while respecting the constraints of both lots.
The project involved the combination and redevelopment of two adjacent lots:
- 673–675: 3,051 sq. ft. (283.26 m²)
- 667–669: 1,855 sq. ft. (172.34 m²)
- Total Site Area: 4,906 sq. ft. (455.50 m²)
The architectural concept followed urban planning and zoning constraints while proposing a contemporary residential development aligned with the market needs and the surrounding built environment.
