The House of Monitors is a home that captures and choreographs light while highlighting the materials of production. Developed in close collaboration with the owners, the Resident Scenic Artist for the National Ballet of Canada, and a shoring engineer with expertise in complex ground conditions, the project designed opportunities to engage materials through framed views, sectional cuts, and layered spatial connections that support understanding of the building’s construction. Carving light through the structure is not only a daylighting strategy, but a way to intertwine interior and exterior, revealing the house as a calibrated sequence of volumes, textures, and luminous atmospheres.

From the sandy soils of the bluff, concrete volumes emerge as inhabitable shoring, forming the structural and spatial framework of the house, while responding directly to unstable soil conditions and minimizing disturbance to the escarpment. Above, a wood volume is cantilevered toward both the street and the lake. Intersections and subtractions between these elements generate sectional depth, cross-views, and a calibrated distribution of light. A centrally located painting studio was developed collaboratively with the owner through iterative studies and virtual light simulations, resulting in a north-facing clerestory and a radiused ceiling that produces even, controlled daylight.

The Scarborough Bluffs lie along Toronto’s East End, where erosion once retreated the land by a metre/year. In the 1960s, conservation efforts planted the bluff to stabilize erosion and protect suburban development that had advanced to the edge. What appears natural today is largely artificially constructed. This condition forms the context for the House of Monitors: a 300-foot-high engineered escarpment supporting a narrow sliver of tableland on a suburban street. In response, the project adopts a restrained footprint and carefully positioned massing to respect neighbouring houses and the fragile edge condition, prioritizing long-term stability, discretion, and stewardship over visual prominence.
Entry occurs beneath the front cantilever through a reeded glass door, providing essential daylight while maintaining privacy along the closely spaced street edge. Concrete forms the service core of the house, anchoring it to the bluff and performing simultaneously as structure, shoring, and thermal mass. Circulation and primary rooms are lined with wood millwork, establishing a tactile counterpoint to the raw structure. Above, white painted light monitors amplify daylight deep into the plan, reducing reliance on artificial lighting. The elemental palette prioritizes durability, repairability, and long-term material performance.

From the street, storage and pantry form a protective service layer supporting efficient organization. Flanking the stair, dining, kitchen, and living open to the lake. Centrally, a 26-foot-tall light monitor creates a vertical volume defined by daylight rather than enclosure, achieving spatial generosity without increasing floor area. Above, bedrooms, office, and a living space open to one another, to spaces above and below, and to the exterior, sharing light and views. The primary bedroom and deck face the lake, while secondary rooms are screened from the street by a slatted façade, allowing spaces to adjust to changing privacy and use.
As a private residence on a sensitive site, the project establishes a model for architectural excellence grounded in restraint, durability, and clarity. It demonstrates how ambition, environmental responsibility, and site stewardship can coexist through careful design.

About Williamson Williamson (WWInc.)
Williamson Williamson (WWInc.) is an award-winning, internationally recognized architecture practice founded by Betsy and Shane Williamson in Toronto. The practice is centered on residential and private institutional projects, with a carefully curated body of commercial work, exhibitions, furniture, and speculative projects. The work is defined by precision, craft, and design excellence at every scale and budget, valuing close collaboration with clients, consultants, and builders.
Multi-generational housing has become a central focus of the practice, responding to both affordability pressures in Toronto’s urban core, and evolving models of family life. Their houses are designed to be readily adaptable, supporting multiple and changing living arrangements while engaging the latent potential for gentle intensification embedded in the city’s fabric. In parallel, they have begun working with affordable housing partners to extend these principles of flexibility, density, and social responsibility beyond the single-family house.
The partners have strong ties to both professional practice and academia. Betsy is Vice Chair of the Waterfront Design Review Panel and co-founder of Building Equality in Architecture (BEA). Shane is a tenured Associate Professor and former Director of the Master of Architecture program at the University of Toronto’s Daniels Faculty. Both are Fellows of the Royal Architectural Institute of Canada.
WWInc.’s work has been widely published and exhibited internationally. Recent recognition includes a Governor General’s Medal for the Garden Laneway House, along with numerous awards from the OAA, RAIC, Canadian Architect, Architect Magazine, and others, including the Professional Prix de Rome for Architecture and the Emerging Voices Award from the Architectural League of New York.
