The House on Ancaster Creek is an award-winning project created by Williamson Williamson—the Toronto-based architecture and design studio—that presents a multigenerational living scenario for aging parents to reside with their adult children.

To allow each generation autonomy, the property has been conceived as two distinct residences—each forming a separate linear bar containing the full program of a home. The L-shaped dwelling creates a landscaped courtyard setback from the street, and runs parallel to Ancaster Creek, after which the home is named.

An L-shaped configuration organizes the ground-floor spaces. The volume that accommodates the grandparents' suite contains a kitchenette, a bedroom, and a private bathroom.

The parents' suite occupies the ground floor, with the living and dining space anchoring the view. A second bedroom and bathroom are adjacent yet separate, as they are meant to serve as a guest room or for live-in care to accommodate the family needs.

The perpendicular volume faces toward the creek. On the ground level, the kitchen, living room, and dining area overlooks a courtyard that contains a small tree.

The suite is laid out as a single-floor accessible apartment with added features to accommodate the specific challenges facing the aging parents. Among them are well-located drains and a master power switch that can be used to mitigate issues with memory loss—for example, if a sink is left running, or an oven left on.

The kitchen anchors the south end of the home. Set in a double-height volume, the 20-foot-tall pyramidal ceiling creates an expansive space that opens to the creek, the courtyard, and above to the sky.

The small second floor acts as a private master suite. This space includes an office, as well as a light-filled cantilevered bedroom that houses the best views of the creek.

Angular geometry and a minimalist touch define the contemporary aesthetic of the residence.

Calacatta marble slabs are meticulously detailed to reflect the surrounding landscape and contrast the heavy, flat-sawn solid oak island with a faceted base.

Sustainability was also at the forefront of the design. To reduce the ecological footprint, energy consumption was decreased through a number of key moves.
