Shop cost = floor area × shell rate + shopfront area × shutter rate + fit-out, then fees and contingency. A 5 m wide, 12 m deep single-storey shop has 60 m² of floor and a 15 m² shutter (5 m × 3 m). At the example rates that is 37,350 before fees and 43,550 all-in, or 726 per m².

Frequently Asked Questions
How do I estimate the cost to build a shop?
Multiply the floor area by a local shell rate, add the shopfront or rolling shutter by its area, add a mezzanine if there is one, then the fit-out per m² or ft². Finish with design fees and a contingency.
How is a rolling shutter priced?
Usually by area: width × height. A 5 m frontage with a 3 m high shutter is 15 m². Motorised shutters cost more than manual ones.
What is shop fit-out?
Everything that makes the shell ready to trade: flooring, ceilings, lighting and power points, shelving or counters, signage and finishes. It can cost as much as the shell for a high-end store.
Is a mezzanine worth adding?
It adds floor space for storage or display without more land. Check head room (often at least 2.1 to 2.4 m above and below) and local rules on how much of the floor it may cover.
Why price a shop differently from other buildings?
Because a shop's shell, shopfront, mezzanine and fit-out are priced differently. The Construction Cost Calculator prices any building from its area and one rate; this one splits a shop into those parts.
