Calgary Deck Builders — Design-Led Decks with the Permit Handled
Arch & Bow builds composite and pressure-treated decks for Calgary and Airdrie homeowners — single-level, multi-level, covered or open. If you're planning to build a deck in Calgary, every project starts with a 3D render you approve before a board is cut, and we handle the permit from application to inspection, so you're not the one figuring out whether your design needs one.

What does Arch & Bow build for Calgary homeowners?
We design and build composite and pressure-treated decks, from a simple single-level platform to multi-level layouts built around stairs, grade changes, or an existing walkout. Every design is rendered in 3D and approved by you before construction starts, and if the design needs a City permit, we handle that too — drawings, submission, and inspection scheduling.
Work is carried out by trade subcontractors with years of hands-on experience in the field — that's the crews' experience, not a company track record, because Arch & Bow is new to direct residential work as of this pivot.
How much does a deck cost in Calgary?
A standard 200 sq. ft. pressure-treated deck typically runs $8,000 to $16,000 installed; the same size in composite runs $14,000 to $22,000. Labour usually makes up 40% to 60% of the total, and a smaller 100 sq. ft. ground-level deck can come in around $5,000 to $9,000.
Verified against HomeStars' 2026 deck construction cost guide, October 2026 — these are Canada-wide ranges, not Calgary-specific figures, since no verified Calgary-only breakdown exists on that page.
| Deck type | Typical installed cost |
|---|---|
| Small ground-level (100 sq. ft., pressure-treated) | $5,000 – $9,000 |
| Standard (200 sq. ft., pressure-treated) | $8,000 – $16,000 |
| Standard (200 sq. ft., composite) | $14,000 – $22,000 |
| Raised deck (200 sq. ft., up to 6 ft. elevation) | $12,000 – $24,000 |
Site conditions, railing choice, stairs, and whether a permit applies all move a quote away from these baselines in either direction — a free consultation gets you a number specific to your yard, not a range.
How much does a 20x20 deck cost?
A 20x20 deck is 400 sq. ft., which runs about $28,000 to $48,000 in composite. Pressure-treated typically comes in 40% to 50% lower — roughly $14,000 to $29,000 — before extras like stairs or premium railings.
Per HomeStars' deck cost-by-size figures (single-level, attached, standard railings), October 2026. The pressure-treated range is our arithmetic on their 40–50% figure.
Per square foot, bigger decks usually cost less, because site prep and setup get spread over more area. The add-ons are what move a 400 sq. ft. quote most: a ground-level stair run typically adds $1,000 to $3,000, and aluminum deck railings run $80 to $150 per linear foot installed.
Do I need a permit to build a deck in Calgary?
You need a City building permit if the deck is covered (a roof or pergola) or its surface is more than 0.6m (2ft) above grade at any point; it costs $205.92 and takes about 7 days. A development permit adds 10 to 12 weeks if the deck sits at the front of the home, closer than 1.2m to a side property line, closer than 6m to the rear line, or in or within 6m of the floodway.

We've written the full breakdown — height thresholds, fees, and timelines — in our Calgary deck permit guide, and every project we build gets a permit check against your specific design before anything starts.
When should you start planning a deck in Calgary?
Start in winter: most deck construction pauses from November to March because footings can't be poured in frozen ground, and a development permit, if your design needs one, takes 10 to 12 weeks. A deck you want by May means design and permit work in February.
Winter pause and booking demand per HomeStars; permit timeline per calgary.ca, October 2026.
Deck builders are busiest from late May through August, and HomeStars notes that booking for April, September or October often means faster scheduling. Getting the render approved and the permit in hand over the winter is how you land one of the first spring slots instead of waiting for midsummer.
What's the difference between composite and pressure-treated decking?
Pressure-treated wood costs less upfront; composite costs more initially but needs far less upkeep, skipping the cleaning and staining or sealing wood needs every two to three years.
Per HomeStars, most homeowners recover that upfront difference within 8 to 12 years through avoided maintenance costs, August 2026.
Which one makes sense depends on how long you're planning to stay in the home and how much deck maintenance you actually want to keep up with. We build both, and can walk through the real tradeoff for your specific project rather than defaulting to whichever is easier to sell. For the full cost and lifespan breakdown, see our composite vs. pressure-treated decking guide.
How does the 3D render and permit process actually work?
Board layout, railing style, stairs, and how the deck steps down with your yard's grade all get modeled in a 3D render you sign off on before a footing is dug — not described to you verbally and hoped for. Where the design triggers a City permit, we prepare the drawings, submit them, and book the inspection ourselves.
Why choose Arch & Bow over another Calgary deck builder?
Most Calgary deck companies lead with years in business or a review count — we can't say either yet, because this is a new direct-to-homeowner offering as of late 2026. What we can say specifically: every project gets a 3D render you approve before construction, and permit handling from application to inspection is included, not an upsell — two things most competitors don't combine into one process.
If a track record matters more to you than a design-and-permit process, we'd rather you know that upfront than oversell it.
Do you build decks outside Calgary?
We build decks across the region, and the permit rules change by municipality — see our Airdrie, Okotoks, or Cochrane deck builder pages for what applies specifically where you live.
