Are you planning a house extension in Calgary or a full home addition? Whether you’re expanding your kitchen to the backyard or adding a complete second story, Tam-Crete Engineering provides the structural expertise your project needs — from load analysis to P.Eng stamped drawings accepted by the City of Calgary. A house addition in Calgary is more than extra square footage. It involves redistributing structural loads across your existing foundation, verifying framing capacity, and meeting Alberta Building Code requirements. Without a licensed structural engineer, your permit application will be rejected — and your construction left exposed to risk.

Why You Need a Structural Engineer for Your Home Addition
Our home addition structural engineer Calgary team evaluates your existing structure before a single wall is touched. We assess foundation bearing capacity, identify load-bearing walls, design beam replacements, and ensure your project is fully compliant with the National Building Code of Canada (NBCC) and local Calgary bylaws. This is especially critical for a second story addition in Calgary, where the original footings must carry significantly more weight than they were designed for. Our APEGA-licensed engineers verify every load path — giving you, your contractor, and the City of Calgary full confidence in the design.

Second Story Addition vs. Rear Addition — Which Is Right for You?
A second story addition in Calgary maximizes square footage without reducing your yard. However, it requires a thorough structural analysis of your existing walls, foundation, and roof system. A rear house extension in Calgary is typically more straightforward structurally but requires new foundation work and careful grading.
Both options require P.Eng stamped plans for permit approval in Calgary and across Alberta. Tam-Crete Engineering handles both — and advises you on the most cost-effective structural approach for your lot and budget.
