Bank construction in Calgary costs more per square foot than almost any other kind of retail space, and the reason is easy to see on the drawings. A branch packs a vault, an alarm system, access control, cameras, bullet-resistant glazing and often a drive-up lane into a small footprint. Every one of those items has its own specialist, its own lead time and its own approval from the institution's security team. We build new bank and credit union branches and refresh existing ones, and most of our work on a branch is coordination.
The vault decides the structure
A UL-rated vault or a large safe is heavy, and the floor has to carry it. In a new building we design the slab for the vault from the start, usually with a thickened, reinforced area under the vault room. In an existing retail unit it is a real question. A slab-on-grade can often take a vault with local reinforcement. A suspended floor, such as a second storey or a unit over a parkade, needs a structural engineer to check the load and usually needs added steel or a new footing.
The vault door and modular vault panels come from specialist suppliers with long lead times. We order them early and build the vault room to the supplier's shop drawings, because a few millimetres off on the door opening means a door that does not hang.
Security systems are designed by someone else, and installed by everyone
Most institutions bring their own security consultant or have a corporate security standard. That standard covers the video surveillance, intrusion alarm, panic buttons and silent alarms at each teller station, access control on staff doors, and the alarm monitoring connection. Our job is to make the building ready for all of it: conduit and back boxes in the right places, power to every device, data cabling to the security room, and walls and ceilings closed only after the security integrator has roughed in.
The mistake we see is treating security as a late trade. If the panic button locations are not on the millwork drawings, someone ends up drilling through a finished teller counter. We put the security consultant's device layout on our coordination drawings before framing starts.
Teller lines and bullet-resistant barriers
Teller counters with bullet-resistant glazing are built as a system: the glazing, the framing that holds it, the transaction trays and the counter die wall behind them all need to meet the same rating. Many newer branches have moved to open pods and fewer traditional teller windows, but the cash-handling areas still need protection, and the institution decides the rating.
Drive-thru lanes and ATMs
A drive-up lane or a drive-up ATM changes a branch from an interior project into a site project. The City of Calgary looks at stacking space for queued cars, how the lane affects traffic on the site, and how it fits the land use district. On a pad site that is part of the development permit. In an existing plaza, adding a drive-up lane usually means a development permit and the landlord's consent, and sometimes there is simply no room for the stacking the City wants.
The ATM itself needs a secured enclosure, power, data, and a concrete base or wall opening rated for the unit. On a drive-up lane, add a canopy, heat tracing for Calgary winters and bollards.
Data, power and accessibility
Branches run on their network, so the data cabling and the comms room are planned to the institution's IT standard, often with redundant connections. Some branches need backup power for security and network equipment.
Accessibility matters more in a branch than in most retail units because every customer reaches a counter or a desk. Lowered transaction counters, clear turning space, accessible washrooms and automatic door operators are part of the base design, not an add-on.
Branch refresh or new build?
A branch refresh in an occupied building is a different job from a new branch. During a refresh the branch often stays open, so we phase the work, keep the vault and security systems live, and do the noisy work after hours. The existing vault usually stays, which saves the biggest cost and the longest lead time.
A new branch, in a new pad building or a retail unit, gives the institution a clean layout but takes on the full vault, security and drive-up scope.
What bank construction costs in Calgary
| Project | Planning range (as of 2026, varies by scope) |
|---|---|
| Bank or credit union branch | $275–425 per sq ft |
That is roughly 60% above typical retail construction per square foot. The reason is the small footprint: the vault, the alarm and security systems and the drive-up equipment cost about the same whether the branch is large or small, so on a compact branch they push the per-foot number up. The vault, the drive-up lane and the security standard are the three items that move a branch from the bottom of the range to the top.
How long a branch takes
The schedule is usually set by the vault door, the security equipment and the bullet-resistant glazing, which are all long-lead items, and by the institution's own approvals. A drive-up lane adds a development permit. We build the schedule around those dates from the first meeting so the interior trades are not waiting on equipment that was ordered late.

What branch managers and facilities teams ask
Can my floor hold a vault?
A ground-floor slab usually can with local reinforcement. A suspended floor or a unit over a parkade needs a structural engineer's review, and often new steel or footings. We check this before the lease is signed.
Who designs the security system?
Usually the institution's security consultant or corporate standard. We build to it: conduit, power, data, back boxes and protected millwork, coordinated before the walls are closed.
Can I add a drive-thru lane to an existing plaza unit?
Sometimes. It usually needs a development permit and the landlord's consent, and the City will look at how many cars can queue without blocking the site. Some plaza layouts simply do not have room.
Is a branch refresh cheaper than a new branch?
Almost always, because the vault and much of the security infrastructure stay. The trade-off is phasing: the branch often stays open, so work is staged and some of it is done after hours.
Why does a bank cost more per square foot than retail?
The vault, alarm and drive-up equipment cost about the same regardless of branch size. Spread over a small branch, they raise the cost per square foot well above a standard retail fit-out.
