Home Additon FAQs
Q: How much does a home addition or garage cost?
It depends on size, complexity and finishes, but here are very rough starting points:
-
Attached home additions: from $175,000+ for smaller one-storey additions, more for larger or two-storey projects
-
Detached garages / workshops: usually $120,000+ depending on size, foundation and finishes
-
Secondary suites / in-law units (ADUs): typically $220,000+ because of kitchens, bathrooms and separate services
We’ll give you a detailed budget range after a site visit and concept discussion.

Yes. We handle engineering, permits and construction for second-storey and dormer additions, including structural upgrades, stairs, insulation and finished interiors.
