Durham Modular Transitional Housing

Montgomery Sisam and NRB were initially commissioned by the Regional Municipality of Durham to provide a test fit and feasibility study. The project was ultimately implemented through a CCDC14 design-build contract, with NRB as the design-builder and Montgomery Sisam as the prime consultant and architect.

The Durham Modular Transitional Housing project challenges conventional expectations of what affordable housing looks like. Rather than opting for an institutional appearance, the design is warm, contextually sensitive, and inspired by the surrounding rural landscape. It also utilizes a modular, off-site prefabrication strategy that allows for rapid construction while maintaining a high level of craftsmanship and design quality. Thoughtful architectural features, such as a Scandinavian cottage-like exterior, large windows, and communal amenities like a fireplace lounge and double-height dining space, help elevate the living experience for residents without increasing costs.

The design draws inspiration from the vernacular architecture of rural Ontario, particularly the area around Lake Simcoe. Elements such as the sloped roof, dark cladding, and light wood accents are reminiscent of local barns, birch trees, and grasslands. These references not only ground the project in its rural setting but also help it blend seamlessly with the surrounding environment, avoiding the stigmatization often associated with affordable housing.

The project is located in a quiet, rural neighbourhood near Lake Simcoe, which played a key role in shaping both the aesthetic and functional aspects of the design. The natural landscape and low-rise residential character of the area informed the building’s material palette, roofline, and siting strategy. Large windows were incorporated to take advantage of the surrounding greenery, and outdoor amenities, such as a semi-private courtyard, a terrace and an outdoor basketball court, were added to enhance livability and foster community.

Commissioned by the Regional Municipality of Durham, the project responds directly to the urgency of the housing crisis in the region. The client’s focus on delivering supportive housing at speed, without compromising dignity or quality, shaped every design decision—from the modular approach to the inclusion of shared amenities that foster a sense of community.

As transitional housing, helping residents overcome barriers to housing factored heavily in the design. A highly flexible double-height dining room and lounge provides a comfortable place for residents to relax and socialize but also provides a place for programming.

This project reflects Montgomery Sisam Architects’ broader commitment to designing with purpose and creating architecture that supports equity, resilience, and community well-being. Like many of the firm’s other works, Durham Modular Transitional Housing demonstrates a balance between innovation, sustainability, and contextual sensitivity. The project builds on the firm’s exploration of modular and prefabricated systems, while reinforcing its belief that all people deserve well-designed and dignified places to live.
