Worldwide Steel Buildings Barndominium Kits: Price and Engineering Review

Updated July 2026 · Barndo Finder research

Worldwide Steel Buildings is a kit manufacturer, not a builder. The Missouri company engineers and ships DIY barndominium shell kits built around an open web truss frame, backs the frame with a 50-year structural warranty, and publishes kit pricing of roughly $10 to $30 per square foot. You still pay separately for the foundation, erection labor, and the entire interior build-out, and that is where most of your money goes.

Key takeaways

• Worldwide Steel Buildings sells engineered steel kits, not turnkey homes. They have run their own truss factory in Peculiar, Missouri since 1983.
• Published kit pricing is $10 to $30 per square foot per their FAQ. Their listed 40x40x12 barndominium kit starts at $75,000, which is about $47 per square foot as configured.
• The signature engineering is the open web truss: clear-span interiors with no interior columns and usable space to the peak.
• Reviews skew positive. 4.6 stars on Google across 72 reviews, 4.8 on Facebook across 19. The BBB profile is A+ accredited, but the 4 reviews posted there average 2 stars, mostly over communication.
• A kit is roughly a quarter of a finished barndominium budget. Our directory pegs national turnkey costs at $125 to $320 per square foot. Budget from that number backwards.

What does Worldwide Steel Buildings actually sell?

They sell engineered steel building kits that you or your contractor erect. The company has operated its own open web truss factory in Peculiar, Missouri since 1983, and it says it has shipped kits to all 50 states. It is an operating company of Fall River Holdings, LLC.

Two frame styles are offered: all-steel, and a wood hybrid that uses wood purlins on a steel truss frame. One Google reviewer said choosing the hybrid on a 24x36 building saved him about $2,500 and made solo assembly easier. Both versions arrive as pre-cut components with a manual, and the company pitches the kits as DIY friendly with phone support during assembly. To see how their offer stacks up against the rest of the field, our kit manufacturer rankings compare engineering, lead times, and fine print across every serious supplier.

What they do not sell is construction. No slab, no erection crew, no plumbers. Some buyers hire a general contractor to erect the shell and finish the interior. Others do it themselves. Either way, that work is a separate contract with someone else, and you manage it.

How much do Worldwide Steel barndominium kits cost?

Their published answer is $10 to $30 per square foot for the kit, depending on options like second floors and wraparound porches. That figure comes straight from the FAQ on their barndominium page.

Their product listings tell a fuller story. The 40x40x12 barndominium kit, a 1,600 square foot footprint, is listed starting at $75,000. That is about $47 per square foot. The listed configuration includes 4 windows, 1 walk door, thermal break insulation, eave and gable extensions, and a trim package, with an 8:12 gable roof. Shipping starts at $499, and the listing notes prices vary by state, location, and customization.

So which number is real? Both, in the way kit marketing usually works. The $10 floor is a stripped frame package. A kit configured the way people actually build a house lands well above it. For context, competitor Titan Steel Structures quotes $25 to $30 per square foot for kits, and Mason Steel quotes $20 to $35. Worldwide's configured listing at $47 is not out of line once you count the included insulation and openings, but it is a long way from $10. Our kit price comparison lays out what each supplier charges per square foot side by side.

What is the open web truss, and does it matter?

It is the reason to shortlist this company. Instead of solid I-beam rafters or wood trusses, Worldwide builds a lattice-style steel web truss in its own factory. The company claims the largest open-web truss facility in the industry, and the design carries their 50-year structural warranty.

The practical payoff is clear span. No interior columns, no load-bearing interior walls, and usable space all the way to the peak. You can put walls wherever you want and move them later. One Missouri owner on Reddit said he picked Worldwide partly because the web truss would stay visible inside his house, and reported the purchase process went smoothly, with his county permit office causing the only delays.

The listed 40x40 kit is rated for a 115 mph wind load and a 20 psf snow load at its base configuration, with engineering adjusted to meet local code where you build. If you are in high-snow Colorado or coastal wind zones, the load package changes and so does the price. Every kit ships with engineer-stamped plans, which your permit office will want.

What is in the kit, and what is not?

The standard kit includes main framing, secondary framing, exterior metal siding, metal roofing, trim, closures, fasteners, and stamped building plans. The 40x40 listing adds pre-punched framed openings, sealants, and color-matched flashing.

The exclusions list on their own product page is the part to read twice: installation, permits, foundation, interior build-out, site prep and grading, the final residential floor plan, and all mechanical, electrical, and plumbing. That is not a knock on Worldwide. Every kit manufacturer excludes the same things. But it means the kit invoice is the start of your budget, not the budget.

We say this on every review we write: real barndominium budgets need line items for land, septic, well or water connection, driveway, and site work before the first bolt goes in. Our cost table breaks those lines out by state.

What do reviews say about Worldwide Steel Buildings?

Mostly good things, with a communication caveat. Here is the spread across platforms as of our research in July 2026.

The Google reviews name individual consultants repeatedly, which usually signals a real sales process rather than a call center. Owners describe help through design, adaptable quoting when plans changed, and a useful assembly guidebook. A general contractor who has erected their buildings across Texas, Colorado, and South Carolina reviewed them positively on delivery and manufacturing quality.

The negative signal is thinner but consistent. The few BBB reviews cite poor communication and service, and 1 of them concerned a general contractor the company had recommended, who the customer alleged took a deposit and did not perform. Third-party reviewer Barndo Guru notes support can slow down in peak season and that steel price swings pass through to buyers. Standard advice applies: vet any recommended contractor yourself, and get current pricing in writing with a validity date.

What will the finished barndominium actually cost?

Plan on the kit being about 20 to 30 percent of the total. Here is the math on the 1,600 square foot 40x40, using Worldwide's published numbers and our directory estimates for Texas, a state where they ship often.

Our shell and turnkey figures are directory estimates pending verified quotes, and they move by state: Oklahoma turnkey runs $130 to $195 per square foot, Tennessee $140 to $210, Colorado $155 to $230. The gap between the $75,000 kit and a $224,000 finished house is foundation, erection, mechanicals, and finishes. Anyone quoting you a finished home for less than $100 per square foot is almost always quoting a shell and letting you discover the rest later.

Check your state's numbers on our cost table, and browse erectors and finish-out builders in the directory. We track 335 barndominium-specific builders across 40 states, including Texas, Oklahoma, and Colorado.

Who fits, and who should look elsewhere?

Worldwide Steel fits the owner-builder and the owner-GC. If you have land, some construction competence or a contractor you trust, and you want a clear-span frame with a long structural warranty, this is a credible shortlist company. It also fits buyers who want the frame visible inside, since the web truss reads as a design feature rather than something to hide.

Look elsewhere if you want one contract and one throat to choke. Worldwide will not build your house, and stitching together a kit purchase, an erector, and a finish-out crew is real project management. If that sentence made you tired, hire a turnkey barndominium builder in your state and pay for the coordination. Our shell versus turnkey guide walks through which route fits which budget and skill set. A construction lender may push you that direction anyway, since many want a licensed GC on residential projects. Our guide to barndominium construction loans covers what lenders expect on kit builds.

Our take

Worldwide Steel Buildings is a legitimate manufacturer with a real factory, 40-plus years of history, and engineering that earns its place on a shortlist. The open web truss is a genuine differentiator, the 50-year structural warranty is unusual, and the review record is better than most companies in this space.

Our two cautions. First, treat the $10 per square foot figure as a doorbuster. Their own configured listing prices at about $47, and that is the more honest planning number. Second, the kit is the easy part of the project. The buyers who end up happy with Worldwide are the ones who budgeted the full turnkey number, lined up their slab and erection crew before ordering, and used the kit savings where they belong: in the finish-out.

Get real numbers for your build

Kit pricing only means something next to erected and finished pricing in your state. Request quotes and we will match you with barndominium builders and erectors near your land, so you can compare a Worldwide kit route against a turnkey bid with actual numbers on both sides.
