Project Description

Located in downtown Hamilton, this new 55-unit, mid rise, affordable housing building will feature a mix of 35 one-bedroom and 20 three-bedroom units. A spacious outdoor area will provide gathering space for the residents. The ground floor level will also house amenity spaces as well as services rooms, utility rooms, and 3 residential units. The remaining 52 residential units will be distributed between the 2nd and 6th floor. A mechanical penthouse will top the building and house all the building services equipment.

Bay Cannon is the first of two buildings slated for the site. KMAI has designed the building with careful attention to site constraints to factor future development.

The building will have a slab on grade, and poured concrete foundations and footings. The main building structure, including the mechanical penthouse, will be steel columns and Deltabeams. Floors will be prefabricated hollow core and solid concrete slabs. Elevator core and exits stairs will be poured concrete. The envelope will be an insulated steel stud structure wall and we will have triple glazed windows. The cladding will be cement board from ground floor to 6th floor and metal siding on the mechanical penthouse.

The goal of Bay Cannon is to create a landmark building for the City of Hamilton by merging affordable housing and Passive House design.
