Home Additions in Calgary

Bump-outs, second-storey additions, garage conversions — Calgary home additions designed, permitted, and built under one fixed-price contract.

Overview

Calgary’s home additions contractor

A Calgary home addition is the cleanest way to gain square footage without moving. We design and build bump-outs, full second-storey additions, garage conversions, and walk-out additions — handling the structural engineering, foundation work, framing, mechanical extensions, and finish work under one contract.

Additions are heavy on the City of Calgary side: development permit, building permit, often a real-property report and lot coverage analysis, occasionally a community board review. We package the submission, manage the back-and-forth with the City, and adjust the schedule when permits land — so you don’t wait on paperwork mid-build.

Why Choose Us

We’ve built additions across every Calgary community board. Setbacks, lot coverage, height limits, real-property reports — handled.

Matched to your existing home

Roof line, siding profile, window styles, interior trim — additions that look planned, not stapled on after the fact.

Live in your home through the build

We seal the work zone and stage the open-up so you can stay in the existing house while the addition goes up alongside it.

Structural engineering coordinated

Foundation design, beam sizing, lateral analysis — all stamped by a structural engineer before the first dig.

Frequently Asked

Questions, answered

How much does a home addition cost in Calgary?

Calgary home additions typically run $350–$550 per square foot of new addition area, depending on whether you’re adding a single bump-out or a full second storey. Foundation work, complex matching, and finishes can push higher.

How long does an addition take?

Bump-outs run 10–16 weeks of construction. Full second-storey additions run 16–28 weeks. Add 8–14 weeks of design and permit lead time before construction starts.

Do I need to move out during a home addition?

Not usually for a side bump-out or garage conversion. Second-storey additions sometimes require short-term accommodation while the roof comes off and the new structure goes up — we plan that window tightly to keep it under two weeks.

What permits are needed?

Development permit (sometimes with community board review), building permit, plumbing/gas/electrical permits if mechanicals are being extended. Most projects also need a current Real Property Report and lot coverage calculation.

Can you match my existing siding and roof?

Yes — we source matching siding profiles, shingle products, and trim from the original supplier when possible. Older homes occasionally need close-match alternatives; we’ll show you samples before committing.
