A 40x60 metal building is 2,400 square feet — twice the footprint of a 30x40, which we build as an installed shell for $95,000 to $115,000. A 40x60 scales up from there, with wall height, overhead doors, and site conditions driving the final number. We quote it against your actual property.
Why we quote this size rather than publish a range
We publish a firm installed price for a 30x40x10 shell because it is a size we build repeatedly at a consistent specification. A 40x60 covers twice the area, and at that scale the variables spread far enough apart that a published range would be misleading rather than helpful.
The honest version: a 40x60 costs meaningfully more than a 30x40, it does not cost exactly double, and where it lands depends on four things we can only price after seeing the site and the intended use.
| Size | Footprint | Installed Shell Price |
|---|---|---|
| 30x40x10 | 1,200 sq ft | $95,000–$115,000 (published) |
| 40x60 | 2,400 sq ft | Quoted per site |
The four variables that decide a 40x60 price
Wall height. The largest single factor, and the one most people underestimate. A 40x60x12 and a 40x60x16 are substantially different buildings — more steel through the whole frame, taller sheeting, larger doors, and a different engineering solution for wind load. It also cannot be changed after the frame is ordered.
The foundation. A 2,400-square-foot slab on North Texas expansive clay is engineered against the actual soil. A slab designed for residential use with plumbing rough-in costs more than a plain shop pour, and soil conditions vary meaningfully across the region.
Openings. Overhead doors are a real line item, and at this size most buildings want several. Tall or wide doors have to be engineered into the frame.
Site work. On acreage, pad preparation, drainage, driveway, culvert, septic, water, and an electrical service run from the road are all separate from the building and genuinely site-specific.
What an installed price covers
Engineered drawings, permitting, pad preparation, the engineered concrete foundation, the steel frame and anchorage, roof and wall sheeting, trim and closures, and the specified doors and windows — erected and complete. Land, extensive site work, septic, well, and utility service runs sit outside it.
Finishing part of it as living space
A 40x60 is a common footprint for a shop-plus-living-quarters build, because it comfortably holds a genuine shop at one end and a real home at the other. Interior finish-out with plumbing, electrical, and HVAC runs $120,000 to $250,000 depending on finish level and how much of the footprint is finished — the same figures that apply to any residential finish-out we do.
The finish-out number tracks finished square footage and specification, not the size of the shell around it. A 40x60 with 1,000 square feet of living quarters finishes less than a fully residential 30x40.

Frequently Asked Questions
Is a 40x60 metal building double the cost of a 30x40?
No — it covers double the footprint but does not cost exactly double, because some costs scale with area and others do not. Where it lands depends on wall height, doors, foundation design, and site conditions, which is why we quote it per site.
What wall height should a 40x60 have?
12 feet suits general shop and storage use. 14 to 16 feet is what RV storage or a two-post vehicle lift requires. Decide before the frame is ordered — wall height is the one dimension that cannot be changed later.
Why are online 40x60 prices so much lower?
Those are almost always kit prices — steel components delivered on a truck, with no foundation, erection labor, engineering, permits, site work, or installed doors. An installed, permitted building is a different product entirely.
Can a 40x60 hold both a shop and living quarters?
Yes, and it is one of the most practical sizes for it — enough footprint for a genuine shop at one end and a full home at the other, with a rated fire separation wall between them.
What does it cost to finish out living space in a 40x60?
$120,000 to $250,000 for plumbing, electrical, HVAC, insulation, interior framing, drywall, kitchen, bathrooms, flooring, and trim — scaled to how much of the footprint is finished and to what specification.
