Self-Storage Facility Construction in Wyoming

Small parcels suit self-storage better than anything else we build. The Cheyenne Business Parkway has 60 acres available in parcels under 15 acres, with gas, electricity and redundant fiber already in place. Ten acres is enough for several rows of buildings, a managed gate and room to add phases later. A storage owner does not need a rail spur or a thousand-foot truck court. A storage owner needs flat ground, drainage and a road.

The product is deceptively plain. Long, narrow steel buildings with roll-up doors, set in rows, with drive aisles between them and a fenced perimeter. Every cost in that plain product is a decision about snow, wind and money. How wide is the aisle once the roof sheds into it? How much of the site drains toward the entrance gate? Which phase gets built first, and what happens to the second phase while the first one fills?

We plan around the drive and the weather, then the work. For storage, that means roads that stay open in a storm, buildings that stand up to the local wind load, and a build sequence that gets revenue-producing units open before the whole site is finished.

Phasing from the first row

Most storage projects are not built in a single pass. The owner opens the first rows, lets them lease, then builds the next. We design the full site up front and build it in phases, with utilities, detention and the drive loop sized for the final build-out. That means the first phase carries a bit more civil cost, and each later phase costs less because the road, gate and drainage are already in.

The first phase should include the office, the entry gate, the lighting and the fence. Customers judge a facility by those items. Phase two is where steel crews return, and we make sure the aisle between phases is protected, with a berm or fence, so lease-up traffic does not meet construction traffic. The same long, narrow steel buildings also serve small bay contractor condos, so a phase can be planned for either use.

What gets built

The scope starts with clearing and grading. Storage sites need to be nearly flat, with a gentle fall to a detention pond or an approved discharge point. We handle that through site clearing and mass grading, topping the subgrade with compacted base rock so that concrete does not move in a freeze-thaw cycle. Slab on grade comes next, usually five or six inches thick with fiber or wire reinforcement and control joints laid out to the door spacing.

Then steel. We erect a pre-engineered metal building in repeated bays with light-gauge partitions, roll-up doors and a standing-seam or through-fastened roof. Climate-controlled buildings add insulation, mechanical units and corridors. The sequence is repetitive, which helps cost, but each row sits on its own pad and has its own grade, so we survey each one before the pour.

What we schedule and supervise

We manage the earthwork, concrete and steel erection on this kind of job as one sequence. That matters in storage because the work is repetitive and the margin is thin. Subcontractors handing off between trades lose a day each time. Trade partners move from grading to pad to slab to steel in a rhythm we schedule, with a single point of responsibility for each row.

Security items are part of the package. Fencing and security integration covers the perimeter fence, the access gate with its keypad and operator, the cameras and the site lighting. Gate operators are bought for the local cold, because many standard units stall at the temperatures this state sees in January. We cover the cabling in conduit below frost depth.

Where a storage budget moves

Land and steel are the big lines. After that, the site is where surprises show up. Rock under topsoil adds excavation cost. A soft spot in a drainage path adds fill. A snowdrift problem adds aisle width, which adds land. The Town of Wright publishes a 30 psf ground snow load, 90 mph wind (exposure C) and a 42 inch frost line, and numbers that differ from Cheyenne's or Evanston's change the steel package and the footing size.

We price the steel to the local design values, not to a generic price book. A building in a 90 mph zone has a different wall girt and bracing package from one in a 105 mph zone. Door size and door type also move the number: a ten-by-ten roll-up costs more than a five-by-five, but earns more rent per unit of floor area. We lay those trade-offs out in a table so an owner can pick the mix that pays.

Where demand grows

Storage follows households and small businesses. In the Casper area, Bar Nunn grew about 35 percent, from 2,213 residents in 2010 to 2,981 in the 2020 census, and Mills grew from 3,461 to 4,034 over the same period. Both are part of the Casper metropolitan area. Those are the towns where a first row of units is worth pricing against the lease-up it could support.

Owners also think about the trucking and distribution trade, where drivers and small contractors need an outdoor parking row or a covered bay. That overlaps with the work described under warehouse construction and, in the right setting, with logistics and distribution customers. We design the site with a few larger units and an oversized aisle for that customer base. Town jurisdictions in Bar Nunn and Mills set their own review rules, and we confirm them first.

Send the parcel and the unit mix

Send the parcel, the unit mix and the phase plan. We will return a site layout, a steel package priced to local snow and wind values and a build order that opens units early.

Common Questions

How many acres does a self-storage facility need?

A useful facility can fit on a few acres, and a large one on ten or more. The Cheyenne Business Parkway has 60 acres available in parcels under 15 acres, which is typical of the parcels storage owners look for. The real limit is drainage, snow storage and aisle width, not land alone.

What does snow do to storage building design?

Roof snow slides into the aisles and drifts between buildings. We choose roof slopes and aisle widths to keep the aisle clear and design the buildings to the local ground snow load. Wright, for example, publishes 30 psf. Other towns publish higher numbers, and we use the local value.

Can the facility be built in phases?

Yes, and it usually should be. We design the full site first, then build the road, utilities and detention to the final layout. The owner opens the first rows early, and later phases cost less because the infrastructure is done.

Do gates and security work in a Wyoming winter?

They do if they are specified for it. We choose gate operators rated for cold, bury conduit below the frost line and light the site for safe snow clearing. We test every gate and keypad before turnover.

Can you build climate-controlled units?

Yes. Those buildings add insulation, vapor control, heating and ventilation, and a different slab detail. They cost more per square foot and earn more per square foot, so we price a mix of drive-up and climate-controlled space and let the owner pick.
