What a Self-Framing Building Actually Costs, by Size
Real per-square-foot pricing, drawn from years of historical Metalex jobs. Here is what small, medium, and large self-framing buildings tend to run, and why size moves the number.
Budget questions come early, and they should. The figures below are per-square-foot pricing drawn from years of historical jobs, excluding buildings with intricate skids, electrical scopes, or highly customized designs. All figures are in CAD. Treat them as an orientation for early budgeting, not a quote.

Planning range
$87 – $175 / ft²
Medium
251 – 600 ft²
Median

Planning range
$63 – $125 / ft²
Large
601 – 1,000 ft²
Median
$78/ft²
Planning range
$60 – $115 / ft²
Why smaller costs more per square foot
The pattern in the table is not a mistake. Smaller is more expensive per square foot because doors, detailing, engineering, and handling do not shrink proportionally with the building. A 12 by 16 foot building still needs a standard man door, windows, a roll-up door, a drawing package, and a delivery. Those costs are spread over less floor area, so the per-square-foot figure climbs.
Larger buildings show the strongest economies of scale, with the 601 to 1,000 square foot tier sitting around $78 per square foot at the median.
What moves you within a range
At the high end of any range, expect elevated eave heights with reinforcement packages, complex openings or penetrations, multi-piece builds, or premium finishes. Those are the same reinforcement thresholds we describe in how tall a self-framing building can go.
Planning note. These figures are for early budgeting orientation only, not a substitute for a project-specific quote. Scope, configuration, and site requirements affect the final number significantly. Pricing is historical and varies by size, height, openings, snow load, insulation, skid or foundation, doors, HVAC, electrical, freight, erection, site conditions, taxes, and current material pricing.
Frequently asked questions
How much does a self-framing building cost?
In CAD, from historical jobs: 100 to 250 square feet lands around $127 per square foot, 251 to 600 around $92, and 601 to 1,000 around $78 at the median. These are budgeting figures, not a quote.
Why is a small building more per square foot?
Fixed items like doors, engineering, the drawing package, and delivery do not scale down with the building, so on a small footprint they raise the per-square-foot number.
What pushes cost to the top of the range?
Elevated eave heights needing reinforcement, complex openings, multi-piece builds, and premium finishes, plus site-driven factors like snow load, insulation, freight, and erection.
