Quick Answer: 50x150 Metal Building
A 50x150 metal building gives you 7,500 square feet of clear span. The kit runs about $52,500–$165,000, which is $7–$22 per square foot. With a slab, erection, site preparation and a permit, expect $136,800–$353,700 installed at a 14 ft eave. Each extra foot of eave adds roughly 3% to the kit. It suits warehouses, arenas, equipment storage and multi-bay shops.
Simplify your research by letting us do the work for you.
Finding enough covered floor for a growing business, a farm operation or a full-size indoor arena is harder than it sounds. A 50x150 metal building gives you 7,500 square feet under one roof with no interior columns to get in the way of trucks, equipment or arena rail. This page works out what a 50x150 metal building costs, line by line, then shows how the price moves with wall height.
It is written for anyone pricing a warehouse, an equipment barn, a shop or an arena. You will find the kit and installed ranges, the price by eave height, what goes into the build, and how the 50x150 metal building compares with the sizes next to it.
Why a 50 x 150 Metal Building Makes Sense
Structural Advantages
At 7,500 square feet you are well past the size where wood framing stays competitive. A 50x150 metal building is usually built on a red-iron rigid frame, which is welded steel I-beam sections bolted together on site. The Metal Building Manufacturers Association publishes the design standards most suppliers build to, and rigid frames span far wider than 50 ft. A column-free 50 ft width is routine engineering, not a custom job.
That clear span matters more at this scale than it does in a small shop. The 150 ft length gives you room for several bays, a mezzanine or an arena with full rail clearance. With no posts inside, you can change the layout later without touching the structure. Loads follow ASCE 7 for your address, and the American Institute of Steel Construction covers the structural steel behind them.
Steel does not warp, rot or feed termites. That counts when you cover three-quarters of an acre under one roof. Maintenance shifts to the finish coating, not the frame. That is a short list.
Economic Benefits
Large buildings cost less per square foot. The kit rate on a 50x150 metal building is $7–$22 per square foot, against $9–$32 on a 30x40, because the engineering repeats along the length and materials ship in bulk. That is a big part of why the 50x150 metal building cost works out lower per square foot than a small shop.
Speed helps too. It also saves money. A pre-engineered kit goes up in a fraction of the time of stick-built work, so you spend less time paying interest before the building starts earning.
Compare bids line by line
Get at least three quotes, and check that each lists the same eave height, doors and drawings. A lower number often just means more is missing.
Sizing Your Building
What the Floor Is For
Confirm the use before you lock in the footprint. Indoor arenas want the full 150 ft for a working rail and turning room. Warehouses and distribution space care more about eave height and door placement than raw length. Farms often split the floor into equipment storage, a shop and covered hay or feed.
Eave height is the choice buyers underestimate most. Tractor-trailer access wants tall walls and tall doors, and an arena wants enough air above horse and rider. Changing height after the frame is engineered is far more costly than choosing it up front, so use the eave table below before you order.
Popular Building Sizes
The 50x100 metal building is about two-thirds of this footprint and costs proportionally less. For more width, the 60x150 metal building keeps the same length and adds 10 ft. It is worth a look if 50 ft is tight for your use.
Building Features Worth Specifying
A building this size is rarely a bare shell. Most 50x150 metal building projects include some mix of the items below, and each one changes the cost and how well the space works.
- Roll-up or sectional doors sized for the vehicles or equipment you move. A door is quoted per opening, because width, height, insulation and opener all change the price.
- Walk doors for staff and safety egress, also quoted per opening.
- Insulation to control heat and condensation. Spray foam runs $1.00–$4.50 per square foot of surface.
- Translucent roof panels for daylight across a 7,500 sq ft footprint.
- Ridge vents, gable vents or powered fans to manage heat and moisture.
- Interior partitions to split the floor into zones without losing the clear span.
- Gutters and downspouts, which matter for drainage at this roof area.
Fix door openings early
Specify the openings before the frame is engineered. Moving or widening one on a fabricated red-iron frame means re-engineering that bay.

Complete Cost Breakdown
Kit and Installed Ranges
The price has two parts. The kit is the steel frame, panels, trim and hardware that arrive on a truck. The installed price adds everything it takes to stand the building on a slab and get it permitted.
For 7,500 square feet the kit is $7–$22 per square foot, or $52,500–$165,000. Installed, the five lines below add up to $136,800–$353,700. Each total is the sum of its lines, and the whole comes to about $18–$48 per square foot.
| Line | How it is figured | Range for a 50x150 |
|---|---|---|
| Building kit | $7–$22 per sq ft | $52,500–$165,000 |
| Concrete slab, 4-inch | $6–$12 per sq ft | $45,000–$90,000 |
| Erection | $5–$12 per sq ft | $37,500–$90,000 |
| Site preparation | Total, varies by lot | $1,300–$5,600 |
| Permit | Total, varies by jurisdiction | $500–$3,100 |
| Installed total | Sum of the lines | $136,800–$353,700 |
These are national ranges for a 50x150 metal building. The low end is a plain building on a level lot. The high end is a heavy-load building on a tight site. Your exact figure comes from quotes for your address, and the form on this page gets you several.
50x150 metal building prices by eave height
Every 50x150 metal building price above is for a 14 ft eave, the shortest wall in the table. Taller doors, a loft or a lift need more height. Each extra foot of eave adds roughly 3% to the kit, while the slab, site work and permit do not change with height, so the installed total climbs more slowly. The size is written width by length by eave: a 50x150x20 is 50 ft wide, 150 ft long, with 20 ft walls.
| Building | Tallest door | Kit | Installed |
|---|---|---|---|
| 50x150x14 | 12 ft | $52,500–$165,000 | $136,800–$353,700 |
| 50x150x16 | 14 ft | $55,700–$174,900 | $140,000–$363,600 |
| 50x150x18 | 16 ft | $58,800–$184,800 | $143,100–$373,500 |
| 50x150x20 | 18 ft | $61,900–$194,700 | $146,200–$383,400 |
| 50x150x22 | 20 ft | $65,100–$204,600 | $149,400–$393,300 |
| 50x150x24 | 22 ft | $68,300–$214,500 | $152,600–$403,200 |
The tallest door is about 2 ft below the eave, because the header and the door's own mechanism take that space. On the tallest walls, erection itself can run $15–$18 per square foot when a crane is needed. That is heavier than the band in the cost table, so ask for it by name.
Slab, Site Work and Permits
A 4-inch slab for 7,500 square feet runs $45,000–$90,000, the second-largest line after the kit. Thicker concrete or extra rebar for heavy equipment costs more. Site preparation is $1,300–$5,600 in total, and the permit is $500–$3,100. Together those two are $1,800–$8,700 on any size. On a big building that is a small slice.
Footings must reach below the local frost line. Soil bearing is the engineer's call. Ask for a soil test before the foundation design, not after. A bad surprise in the ground costs far more than the test.
Codes come from the International Code Council, but each state and county adopts its own edition. Check which one applies before you order.
Ask what each bid includes
The slab, site work and permit are often left out of a supplier's first number. Ask what is in the quote before you compare two bids.
Regional Costs
Where you build changes the price. Metro and coastal erection crews charge 25–40% more than rural ones. Buyers in the Northeast and California should expect totals 30–50% above the national ranges here, and the South and Midwest tend to land 5–25% below them.
Engineering follows the address too. Snow load, wind and seismic zone are set by where the building stands, and they can change the frame and the panels. The free ASCE hazard tool returns the loads for any street address. Seismic zones and coastal wind zones add engineering that most of the Midwest never needs, and none of it is optional.
For a smaller building in the same region, the 40x80 metal building page is a useful cross-check.
Confirm the code edition
Many jurisdictions still enforce an older building code than the newest one published. Ask your local department which edition applies, because it decides which load tables the engineer uses. The International Code Council tracks adoption by state.
DIY vs Professional Installation
Some buyers with a crew consider raising their own kit to save on labor. At 7,500 square feet the picture changes. Red-iron erection at this scale means heavy members, crane work and precisely bolted connections across a 150 ft run. Mistakes here are structural, not cosmetic. Hire it out.
Erection is $37,500–$90,000 of the 50x150 metal building cost, so the saving looks tempting on paper. It assumes no mistakes, no injuries and no delays. A professional crew brings insurance, experience with frames this size and familiarity with the inspection your building department will require. Most also warrant their workmanship separately from the material warranty.
Steel erection is a crew job
Erection involves crane operation, work at height and heavy members. Read the OSHA steel erection rules before you decide who stands it. A building this size should go to a crew experienced in commercial steel, not a general contractor outside their usual work.

Frequently Asked Questions
The kit runs about $52,500–$165,000, which is $7–$22 per square foot of floor. With a slab, erection, site preparation and a permit, a 50x150 metal building is about $136,800–$353,700 installed at a 14 ft eave, or $18–$48 per square foot.
A 50x150x20 is 50 ft wide, 150 ft long, with 20 ft walls, tall enough for an 18 ft door. The kit is about $61,900–$194,700 and the installed total is about $146,200–$383,400. The slab, site work and permit stay the same as at 14 ft.
Each extra foot of eave adds roughly 3% to the kit. Going from a 14 ft to a 20 ft eave moves the kit from $52,500–$165,000 to $61,900–$194,700 and the installed total from $136,800–$353,700 to $146,200–$383,400.
Common uses include warehousing, distribution, indoor riding arenas, equipment storage and multi-bay shop space. The clear span leaves the floor free of posts, so the layout can change later.
Almost always. A slab gives the frame a stable base and meets code. At $6–$12 per square foot, a 4-inch slab for 7,500 square feet is $45,000–$90,000. Heavy equipment or an arena floor may call for different concrete, so tell the crew what will sit on it.
The erection band is $5–$12 per square foot, or $37,500–$90,000 for 7,500 square feet. On the tallest walls, a crane can push it to $15–$18 per square foot. Crews in metro and coastal areas charge 25–40% more than rural ones.
Most include at least one large door for vehicles or equipment, plus walk doors for egress. A door price depends on width, height, insulation and opener, so it is quoted per opening. Settle the count before the frame is engineered.
Almost certainly. Nearly every jurisdiction requires one, and permits run about $500–$3,100. Most want drawings sealed by an engineer licensed in your state, so ask the local building department what it needs.
Once engineered drawings are approved and materials arrive, erection takes several weeks for a building this size. The whole project, with permitting, foundation curing and site work, commonly runs three to six months.
The primary red-iron frame is engineered for your site, and panel gauge is a quote item. Heavier panels and frames are priced in your quote, because wind and snow loads set what the engineer specifies.
Final Thoughts on Building at This Scale
A 50x150 metal building is a serious commercial-scale project, and still one of the cheapest ways to get 7,500 square feet of column-free space under one roof. It is $136,800–$353,700 installed at a 14 ft eave, and the kit alone is $52,500–$165,000. Pick the eave height first. You cannot change it later.
Then get quotes. The ranges here show what is normal, and the bids show what your site will cost. Compare at least three, and make sure each lists the same doors, wall height and drawings.
