Home Additions
When a Waterloo Region family outgrows their home, moving is not always the better answer.
When a Waterloo Region family outgrows their home, moving is not always the better answer. Between land transfer tax, agent fees and today's prices, building the space you need where you already live often makes far more financial sense.
Additions are the most technically demanding residential work there is — foundation, structure, roof tie-ins, and matching an existing building so the result never looks bolted on. That is precisely why they belong with a team that manages the whole process.

Home Additions FAQ
Your questions, answered.
Additions in Waterloo Region generally run $90,000 to $300,000+ depending on size, foundation type, and whether you're building up or out. Feasibility and a real number come out of the initial consultation and site review.
Always. Additions require stamped drawings, structural engineering and a building permit from your local building department. We manage the drawings, the application and the inspection schedule as part of the project.
That's the whole craft. We match rooflines, siding, brick, window proportions and interior trim so the addition reads as though it was always there — not like something bolted onto the back.
