Self-storage building kits, complete and shipped

Wasatch self-storage building kits ship the entire steel building system as a coordinated package: stamped engineered drawings, primary rigid frames, secondary purlins and girts, wall and roof panels, every piece of trim, all fasteners and sealants, and the roll-up doors that turn a metal storage building kit into rentable units. Pre-cut, pre-punched, labeled for sequenced assembly, and delivered on a single coordinated trucking schedule.

A self-storage building kit is the most cost-efficient path to a finished facility when the owner has erection capacity (their own crew, a hired erector, or an arrangement with a local steel contractor) and wants the kit-level price basis. Wasatch sizes and engineers the kit, you put it up. Most building kit projects run between $12 and $28 per gross square foot at the kit level, with the remainder of the all-in cost living in foundation, sitework, utilities, and finish.

Every Wasatch metal storage building kit is engineered to the specific snow, wind, and seismic loads of the jurisdiction it ships to. Owners building in 110 lb snow country get a heavier steel package than owners in 30 lb regions. That matters at year ten and year twenty: a generic catalog kit engineered to the lightest possible load saves dollars on the bid and costs them in re-inspections, snow damage, or premature failure later.

Building kits make sense for self-storage, mini storage buildings, portable self-storage units, single-story drive-up facilities, boat and RV storage canopies, and steel commercial shells. Standard widths run from 20 feet to 200 feet in 5-foot increments, with the most common self storage building kit footprints at 30x150, 40x100, 50x100, and 50x200. Custom widths and lengths are available on every project.

One team handles design, engineering, fabrication, and construction. One contract, one schedule, one number you can hold us to.

What a kit covers and what it does not

A complete Wasatch self-storage building kit covers the structural steel package, the building envelope (walls, roof, trim, fasteners), and the storage doors. It does not include foundation work, sitework, utilities, electrical, HVAC, fire suppression, paving, signage, or facility-management software. Owners or their general contractors handle those scopes separately. The kit-vs-all-in distinction matters at proforma: the kit is typically $12 to $28 per gross square foot; all-in single-story self-storage runs $70 to $110 per rentable square foot once site, utilities, soft costs, and FF&E are added.

Stamped engineering travels with every kit. That includes foundation reaction loads, anchor bolt patterns, snow and wind design assumptions, and erection sequencing. Building departments accept the package directly for permit submission, and structural engineers reviewing the design can verify load paths against the project's actual site conditions.

Wall panels, roof panels, trim, and doors are finished in baked-on coatings built to resist peeling, flaking, and fade over Galvalume-coated steel, with EP3 corrosion-proof door springs standard. Color options on doors and trim cover the full storage-industry palette, including high-visibility branding accents (Patriot Red, UB Yellow, Wasabi Green, Royal Blue) for facility identity.

Future expansion is engineered in from day one when the owner specifies it at contract. Original frames sized for planned bay additions mean expansion bays bolt directly into the existing structure without re-engineering or wall removal. That is the difference between buying a building today and buying a building you can grow into.

How a building kit project moves

Whether the owner is putting up a 5,000 SF mini storage building, a 50,000 SF self storage facility, or a 100,000 SF commercial shell, the kit project follows the same five stages.

  1. 01

    Sizing and concept

    Building footprint, eave height, bay spacing, unit mix (for storage applications), and jurisdictional load envelope. Owner confirms erection plan (own crew, hired erector, or local steel contractor) so the kit package can be tuned to the assembly team.

  2. 02

    Quote and contract

    Wasatch returns a line-itemed kit price: steel, panels, doors, trim, fasteners, drawings, and freight. Owners can compare directly against any competing self-storage building kit or metal building kit quote on equal terms.

  3. 03

    Engineering and stamped drawings

    Architectural and structural drawings stamped by licensed engineers in the project's jurisdiction. Includes foundation reactions, anchor bolt layout, and erection sequencing. Permit-ready package delivered to the owner.

  4. 04

    Fabrication and freight

    Steel package, panels, doors, trim, and fasteners fabricated to the stamped drawings. Pre-cut, pre-punched, labeled. Trucking coordinated against the owner's site readiness — foundation poured and cured before kit delivery.

  5. 05

    Owner erection with support

    Owner's crew, erector, or local steel contractor assembles the kit per the erection guide. Wasatch tech support hotline covers questions that come up during assembly. Optional: Wasatch field crew available for turnkey erection on kits in the Mountain West.

Questions

Stamped engineered drawings (architectural and structural), anchor bolt plans, primary frames, secondary framing (purlins, girts, eave struts), wall and roof panels, trim, bracing, all fasteners, and roll-up doors. Site work, foundation, electrical, fire suppression, asphalt, and security are not included.

A 10,000 square foot single-story kit (steel only, doors included, no site work) typically runs $14 to $22 per square foot. Costs scale roughly linearly. Climate-controlled kits add insulated panels and run $20 to $30 per square foot. Shipping is freight-on-board the manufacturing facility; trucking is added at delivery.

Yes. Every kit ships with stamped drawings engineered to the wind, snow, and seismic requirements of your specific site. We coordinate with local building departments on permit submittal questions.

Yes. Kits are designed to allow expansion (additional bays added to length) without re-engineering the original structure. Specify the planned expansion at design time so the original frames are sized for it.

Mini storage buildings is the older industry term for what is now called self-storage; the building type is the same. The phrase typically refers to single-story drive-up facilities with individual roll-up doors. Storage units buildings (the rentable shell that contains the units) and the structural kit ship together as one engineered package.
