Building a helicopter hangar isn’t a job for a generalist. Aircraft don’t tolerate sloppy clearances, undersized doors, or columns inconveniently planted in the middle of the maneuvering space. When the bird coming in is a Life Star medical helicopter — life-or-death missions, day or night, in any weather Tennessee has on offer — the building underneath it has to perform on the kind of margins that don’t leave room for second drafts. Flatrock Motor Club came to East Tennessee Contractors with that exact challenge: build a hangar that could handle a Life Star helicopter, fit the architectural language of the rest of the property, and stand up to East Tennessee weather year after year without high-touch maintenance.
A 3,000 Sq Ft Pre-Engineered Metal Building Hangar
The result is a 3,000-square-foot pre-engineered metal building hangar in Rockwood, Tennessee — 50 feet wide by 60 feet long, with a 30-foot eave height and a single 50-foot by 20-foot door opening designed and engineered to swallow a helicopter whole. The structure is fully welded and steel-framed for the kind of door span that wouldn’t be possible in a conventional wood-frame build. Inside, the building is clear-span. There are no internal columns to maneuver around, no posts in the wrong place, no load-bearing surprises that limit how the hangar can be used.
Why Clear-Span PEMB Construction Works for Aviation
That last detail — the clear-span interior — is one of the underrated advantages of pre-engineered metal building construction for any commercial space, but especially for aviation work. A clear-span PEMB delivers the wide, column-free interior that an aircraft needs, the kind of layout flexibility a working business demands, and the structural strength to handle a 50-by-20 door opening at a 30-foot eave height. Trying to achieve the same span and clearance with conventional construction would be cost-prohibitive, slow, and structurally compromised in ways that matter when a Life Star is parked inside. PEMB is the right tool for this job, and it’s the right tool for hundreds of commercial East Tennessee builds that don’t always realize it.
Refined Architecture Meets High-Performance Steel
The other piece of this project that makes it stand out is the exterior treatment. A high-performance metal building can look like exactly that — a pure utility structure with no architectural interest. That’s not what Flatrock Motor Club wanted. The property as a whole has a refined, hospitality-driven aesthetic, and the hangar had to fit that language without giving up the structural performance of a PEMB. East Tennessee Contractors solved it by integrating a wood-framed section into the building and finishing the exterior in board and batten siding. From the outside, the hangar reads like a thoughtfully designed accessory structure that belongs to the rest of the campus. Inside, it performs like the high-clearance, clear-span, fully-welded steel building it is. Both halves of the goal got hit.
Single-Point Accountability on a Technical Build
Pulling that off cleanly comes down to how the team is structured. East Tennessee Contractors handles design, engineering, structural welding and framing, exterior trades, and finishing in-house. We don’t farm out project management to outside firms, and we don’t run jobs through a relay race of independent subcontractors that nobody is fully accountable for. On a building like this — where the door opening, eave height, weld specifications, hangar door function, and exterior aesthetics all have to come together with no excuses — that single-point accountability is exactly why a project this technical comes together cleanly.
Why PEMB Dominates Commercial Construction in East Tennessee
Quick installation is one of the practical benefits of pre-engineered metal buildings, and it’s a reason PEMBs continue to dominate East Tennessee commercial construction for warehouses, equipment storage, manufacturing additions, retail, and aviation. The same factory-engineered approach that gets a hangar in the air faster gets your warehouse, garage, equipment building, or commercial expansion online faster. Steel doesn’t care about Tennessee’s weather swings. The maintenance demands are dramatically lower than wood-frame commercial construction. The structural performance — including for high-wind events and snow loads at higher elevations — is exactly what a working commercial building needs.
What the Hangar Means for Flatrock Motor Club
For Flatrock Motor Club, the hangar means a Life Star helicopter has a permanent, weather-tight home on the property. For the surrounding community, it means emergency air response is closer and more reliable when minutes matter. For other East Tennessee businesses thinking about aviation, equipment storage, or any commercial structure that needs height, span, and durability, this project is a clean example of what’s possible when a pre-engineered metal building is engineered, fabricated, and installed by a contractor that does all three under one roof.
There’s another piece of this build worth calling out for any East Tennessee property owner considering a metal building project: the architectural flexibility on the outside is real. The choice between “PEMB” and “looks like a building that belongs on the property” is a false one. With a contractor who can integrate wood framing, mixed siding, custom trim, and architectural detailing into a steel-framed shell, the structural advantages of pre-engineered metal building construction don’t have to come at the expense of curb appeal. Aviation hangars, equestrian facilities, retail spaces, agritourism venues, and high-end accessory structures all benefit from this approach — and Flatrock Motor Club is a working example of what it looks like when it’s done right.
