Home Additionsin Montreal
Add a garage, sunroom, second floor, or rear addition. We manage structural engineering coordination, permits, construction, and all interior finishing - under one contract.
The Problem We Solve
Why homeowners in Montreal choose us
Home additions are among the most complex residential construction projects. They require structural engineering, foundation work, exterior integration, and coordination with all existing mechanical systems. They also require specific permits and inspections that general contractors without this experience often mishandle. We have completed additions ranging from garage builds to full second-floor additions across Montreal, and we understand the structural and regulatory requirements involved.
