Toronto-based architecture firm Williamson Williamson has completed a stunning home that embraces aging in place with a sustainably minded footprint. Located in the Ontario town of Hamilton, the House on Ancaster Creek comprises two distinct residences—one for the clients and the other for their elderly parents. The multigenerational home also reduces its energy demands with a 10KVa solar array, daylighting techniques, and low-energy fixtures throughout.
Conceived as a high-density solution, the House on Ancaster Creek combines the functions of two separate homes into a single L-shaped entity. To accommodate any future mobility limitations, the architects placed the parents’ suite on the ground floor, where it’s joined with additional living spaces. Elder-friendly design considerations and features were also incorporated, such as the well-located drains and a master power switch that can immediately switch off any fixtures accidentally left on due to memory loss.
The second floor master suite is accessed via a dramatic wood-clad spiral staircase that ascends from the first-floor living room located at the intersection of the two rectangular volumes. The main residence is positioned parallel to the creek and overlooks the views through floor-to-ceiling glazing. Full-height glazing is also used throughout the home to create a seamless connection with the outdoors. The material palette also reflects this connection: the ground floor of the home is clad in three-and-a-half-inch thick locally quarried Algonquin limestone while timber is used throughout.
Despite the abundance of glazing, the home manages to keep energy demands to a minimum thanks to a highly insulated envelope and a high-performance triple-pane wood-frame window system with an average Uw of .77. Radiant heating is also used to complement a high-efficiency furnace, while LEDs and low-energy fixtures are installed throughout. A 37-module 9.8 kW solar array is installed on two of the flat roofs to offset energy consumption.
