What a 40x50 Footprint Actually Looks Like
Drawn to scale from the same specification the price above comes from. Door, window and interior layout aren’t shown because every Northcraft building is engineered to your plan — what’s fixed at this size is the footprint, the clear span and the eave height.
What Fits in a 40x50 Footprint
2,000 square feet, clear span, no interior columns, at Northcraft’s full 40-foot C-channel width.
Shop With Storage Bays Behind It
The full 40-foot width up front for a work bay with equipment turning room, and 10 extra feet of length behind it for parts storage, shelving, or a second small bay.
Commercial Equipment Building
2,000 square feet of clear-span floor for a small fleet of commercial vehicles or equipment, with no interior post breaking up the layout.
Five-Bay Garage or Fleet Storage
Line up vehicles across the 40-foot width with room to spare, or use the depth for a mix of parking and a dedicated maintenance bay.
Ag Operation Building
Wide enough for equipment to turn, long enough to add real storage capacity for feed, tools, or implements alongside it.
Using a 40x50 as a Shop
2,000 square feet at a full 40-foot clear width. Enough for two working bays side by side with a shared aisle, or one bay plus a genuine parts and bench area that does not get crowded out the moment a project lands.
This is the last size before the price curve flattens — past here you are buying length at a steadily lower cost per square foot, so if you are unsure between this and a 40x60, the bigger building is cheaper per foot than the jump looks.
Two things worth settling before engineering rather than after, because both are far cheaper to change on paper:
- Whether this is one bay or two. Two working bays sharing an aisle need different door placement from one large bay. That is engineering, so decide before the drawings are stamped.
- Eave height, if a lift is in the plan. A standard 10-foot eave is below the minimum most lifts require. Give your estimator the model and we will price the right eave.
What a 40x50 Costs Beyond the Building
$23,600 covers stamped engineering drawings, the building components and freight. Concrete is separate, and 2,000 square feet is roughly where a slab stops being a residential job and starts being quoted like a commercial one - different crews, different scheduling, sometimes a different price per foot in your favour.
We still will not publish a figure. At this size the dominant variables are site access and subgrade, and both are specific to your address in a way no national average survives.
Get real local quotes for 2,000 square feet with a thickened perimeter, and ask whether they would price it as a commercial pour - the answer sometimes moves the number down. Your stamped drawings carry the anchor-bolt layout and we send it to them directly.
The other items priced separately: doors and windows, insulation, and erection.
How Close 40x50 Runs to Northcraft’s I-Beam Pricing
At 2000 square feet, $23,600 works out to $11.80 per square foot, and the family keeps getting more efficient from here — 40x60 runs $11.58/sq ft. What’s more interesting is how 40x50 compares across the frame-type line rather than within its own family: 50x50, Northcraft’s smallest I-beam building, runs $11.92 per square foot at the same 50-foot length. That’s a much smaller gap than the one further up the list (see the 40x40 page for how wide that gap gets at longer lengths) — at this particular length, the I-beam step-up costs less of a per-square-foot premium than it does elsewhere on Northcraft’s price list.
A 2,000-square-foot pour is priced against the stamped engineering drawings, which also confirm whether your specific configuration stays C-channel or needs the I-beam basis — that decision isn’t made unilaterally off a floor plan sketch. Foundation work is priced separately from the building price and available on request. Freight at this footprint is a full mid-size package; site access for the delivery vehicle is worth confirming with your estimator if your lot is tight.
What “Five-Bay” Actually Means Across 40 Feet
The configurations above mention fleet or five-bay parking across the 40-foot width — worth spelling out what that assumes. Standard full-size vehicle bays run roughly 10-12 feet across including clearance to open doors, so 40 feet comfortably divides into three to four full vehicle bays, or more if some of that width goes to smaller equipment, ATVs, or motorcycles instead of trucks. The 10 extra feet of depth on this size over a 40x40 doesn’t change that math — it adds a separate storage zone behind the parking, not more bays across the same width.

Frequently Asked Questions
What does a 40x50 steel building cost?
Northcraft's published floor for a 40x50 is $23,600, delivered, at a 10-foot eave height with standard loads (ground snow to 35 lb, wind to 110 mph). That covers stamped engineering drawings, the building components, and freight — not doors, windows, insulation, concrete, or erection.
How much does a concrete slab cost for a 40x50 metal building?
Northcraft prices foundation work separately (that service is available — ask for it in your quote request) and won't publish a figure. 2,000 square feet is roughly where a slab stops being quoted as a residential job and starts being quoted as a commercial one - sometimes at a better price per foot. The dominant variables are site access and subgrade, both specific to your address. Get local quotes for 2,000 square feet with a thickened perimeter, and ask whether they'd price it commercially.
Is a 40x50 metal building the same as a 40x50 steel building?
In everyday use, yes — most buyers say "metal building" and "steel building" interchangeably, and we answer to both. The distinction worth caring about is the frame, not the word. A solid frame like the C-channel in a 40x50 is a different structure from a hollow tube frame, which is what most of the cheapest advertised carport-style buildings use. Two buildings can both be sold as a "40x50 metal building" and not be comparable products.
What's the real difference between 40x40 and 40x50?
Ten extra feet of length — 400 more square feet — while keeping the same full 40-foot clear-span width. Buyers who want the 40x40's equipment-turning room but need more storage or a second work zone typically move up to the 40x50 rather than a wider building, since 40 feet is already Northcraft's widest C-channel span.
Is 40x50 still clear span, with no interior posts?
Yes — 40 feet is the widest clear span Northcraft builds in C-channel, so a 40x50 has zero interior columns across the full 2,000 square feet.
Do I need a permit for a 40x50 steel building?
Most jurisdictions require a permit for a structure this size. We provide the stamped engineering drawings your local building department will ask for.
Can I customize the building, or is 40x50 a fixed size?
Every Northcraft building is fully customized to your exact specifications — this isn't a catalog of fixed sizes. Bring your own dimensions, door and window placement, and requirements, and we'll engineer to those specs instead of a preset.
What's included in the price, and what isn't?
Included: stamped engineered drawings for your state, every structural and panel component, and freight to your site. Not included: doors and windows, concrete or foundation work, and erection — priced separately; those services are available.
What loads does the $23,600 floor assume, and what raises it?
The floor is based on ground snow load up to 35 lb per square foot and wind speed up to 110 mph. Eave height above the 10-foot basis, higher snow or wind ratings, and high seismic activity all move the price. C-channel buildings like this one typically don't carry collateral load (a crane, heavy mezzanine, sprinkler system) — that's mainly a consideration on Northcraft's I-beam buildings.
Can I erect a 40x50 myself, or do I need a crew?
At the full 40-foot clear span, most buyers hire a professional erector or bring in an experienced crew for a building this size. Our buyers' guide covers the real cost and time trade-off before you decide.
How long does a 40x50 building take from order to delivery?
Typically 45-60 days from order to delivery, depending on engineering review and current production volume. Your estimator confirms a real date range once your drawings are finalized.
If I might need I-beam eventually, is it worth starting at 40x50?
There's no cost penalty for starting here and being wrong about future needs — 40x50's per-square-foot number is close to 50x50's despite one being C-channel and the other I-beam (see the comparison above), so you're not leaving much on the table either way at this length. The real question is whether 40 feet of width covers what you're doing today. If it does, there's no structural reason to pay for I-beam capacity you don't need yet.
