Aviation, Hangar and Right-Sized Commercial Construction in Greybull, Wyoming
A 7,003 foot runway at 3,941 feet of elevation tells a hangar builder what to plan for before the first drawing: wide-span frames, doors that clear a wingspan and a slab that carries aircraft and tugs. South Big Horn County Airport (KGEY) at Greybull is owned by the county and has a 7,003 foot asphalt main runway. A firefighting air tanker operator flew from the field until declaring bankruptcy in 2005. A field with that history has real aviation infrastructure, and hangars, aprons and support buildings are work we know how to build.
Greybull is in central Big Horn County at 3,796 feet, with a cold semi-arid climate, a record high of 109 F and a record low of minus 39 F. That range of 148 degrees punishes buildings. Steel moves, sealants age and doors stick, so we detail for movement and choose hardware rated for it. We design heating for the cold nights and ventilation for the summer afternoons inside a closed hangar.
The town had 1,651 residents in the 2020 census, down from 1,847 in 2010. We say that plainly because it shapes how we advise owners: build what the market can carry, design for reuse and phase the rest.
Hangars, shops and the buildings around the airfield
An aircraft hangar comes in a few forms. A T-hangar suits a small plane and fits many on a small footprint. A box hangar holds one larger aircraft or a few small ones. A shop hangar holds aircraft and tooling for maintenance. Each has different door types, floor slopes, heat and fire protection, and we help you choose the one that matches the aircraft and the business. Floors slope slightly toward the door and drains, electrical outlets sit high enough to stay clear of fuel vapors where the code requires it, and a man door beside the large door lets people in and out without opening the whole wall.
The buildings around the airfield matter too: a fixed-base operator's office and lounge, fuel storage, a maintenance shop, parts storage and a ready room for crews. We build them as clear-span rigid frame buildings with large doors and generous eave height, so the interior is flexible and the owner can reconfigure it as the use changes. Insulation is worth the money here. A hangar that holds heat through a minus 39 F night protects the aircraft, the engines and the people working on them, and it cuts the fuel bill every winter.
Airport ownership, height review and fire protection
The county owns the airport, so most hangar projects on airport ground begin with a lease or a permission from the county. We ask early who approves the lot, what the lease terms are and what design standards the airport applies. Near a runway, structure height and location can also be subject to federal aviation review, and we confirm whether a notice is needed before design.
Fire protection depends on hangar size and use. Larger hangars and those used for fueling or maintenance can require suppression systems, and the local building and fire officials decide what applies. Wyoming has no single statewide building code, so we confirm the local requirements first. We prepare the permit package and answer comments so approval does not become the longest item on the schedule.
Door, slab and the cost of right-sizing
The door is often the largest single cost in a hangar. A bi-fold or hydraulic door that opens the full width is more expensive than a sliding door, but it can save space and time. Slab thickness and reinforcement are the next factor, because aircraft and tow equipment concentrate loads. We price options for both and show the effect on the budget.
With a town that has lost population over the last decade, we do not recommend spending beyond what the market supports. Build the first hangar, lease it and add the next when demand is clear. We design the site, utilities and apron to allow for expansion, so the second building does not require rebuilding the first. The same logic applies to buildings for public sector owners such as the county that manages the airfield.
Reuse before new construction
In a town of this size, there may be older buildings that can be reused. Our renovation and adaptive reuse approach surveys structure, roof, slab, utilities and code compliance, then prices the repair against a new building. Sometimes the old shop is worth keeping with a new roof and doors. Sometimes it is not, and we say so.
For new construction, we pick a simple form, a durable exterior and mechanical systems that the owner can maintain. We avoid features that need specialist service, since the nearest specialist may be a long drive away. A plain building that works in minus 39 F is better than a complex one that fails when the wind blows. Owners who plan to lease space to others should ask us about shared utilities and separate meters, which let each tenant pay for their own use.
What we do from slab to door
We handle site grading, utilities, concrete aprons and slabs, steel erection, roofing, insulated walls, overhead doors and interior build-out. We schedule and supervise the concrete placement and finishing, and we coordinate the ironworkers who erect the frame. Aprons are poured with joints that match the traffic and the drainage pattern, so water does not stand where aircraft or vehicles move. We coordinate any work that touches the active airfield with the airport owner, schedule it around operations and keep equipment and materials out of areas that must stay clear.
We also work in nearby towns. If your program includes buildings in Lovell or Worland, one crew can build them with the same details. We drive to the site and price the drive, and we list it on its own line.

Questions Owners Ask
What type of hangar should I build?
It depends on the aircraft and use. A T-hangar is economical for small aircraft, a box hangar suits a larger plane, and a shop hangar adds maintenance space. We ask about your aircraft, your wingspan and your plans, then price the options.
Do I need approval from the county to build at the airport?
Usually, yes, since the county owns the airfield. We ask early about the lease, the lot and any design standards, and we confirm whether a federal height review applies. These steps come before design.
How do you design for a 148 degree temperature range?
We detail connections and sealants for movement, choose hardware rated for the range and size heating and ventilation for the extremes. Doors get special attention because they bind when the building moves.
Should I build big now or phase it?
Given the town's recent population trend, we usually recommend phasing. Build what you can lease or use now, and design the site for expansion. That way you avoid carrying an empty building.
What is the best way to get a price?
Send us the aircraft, the lot and the date you need it. We will visit, review the lease and give you a written estimate with the door, slab and drive costs listed on their own lines.
