An Off-Grid Canadian Cottage Balancing Design and Sustainability

Armstrong Cottage is an off-grid, net zero retreat in Peterborough, Canada, designed by Peter Braithwaite Studio for a Toronto family. Built on an island with difficult access, the project required barges, floating docks, and winter ice crossings to transport materials and machinery.

The house is made up of two pavilions—one for living, one for sleeping—set on steel columns anchored directly into bedrock. This reduced the need for concrete and minimized impact on the island’s soil and vegetation. The superstructure was designed as a kit of parts, using wood and steel beams, laminated frames, and rafters that could be delivered by barge and assembled with plates and bolts.

Feature exposed wood, vaulted ceilings, and full-height glazing that frame the surrounding forest and lake. A central fireplace anchors the living space, skylit corridors add brightness, and a loft creates a flexible area for children. The result is a durable, efficient cottage that balances family use with environmental responsibility.
