Roslin House is a complete renovation and addition to a semi-detached home in Toronto’s Lawrence Park neighborhood. Exposed Douglas fir glulam beams span the main floor and cantilever beyond the original walls, creating rare second-floor width. A palette of Super White quartzite, grey elm millwork, and oak flooring brings warmth and refinement. Carefully framed views, sculptural stairs, and natural light animate the interiors. Quiet nods to family and personal history—like a pennant-shaped steel detail—add resonance. Clad in pale fiber cement siding with blue-grey steel accents, the addition is both modest and inventive, expanding space while deepening the home’s character and meaning.
