Barndominium Builder in Tennessee — What to Know
Barndominiums — metal buildings with living quarters built inside — have exploded in popularity across rural Middle Tennessee. They combine the cost efficiency of post-frame construction with the livability of a custom home, making them particularly attractive for Lawrence County and Giles County property owners who want to build on rural acreage without the price tag of traditional custom home construction.
What is a barndominium?
A barndominium starts with a post-frame or steel-frame structure — the same basic construction used for agricultural pole barns. Instead of leaving the interior as an open barn, the living quarter portion is fully insulated, drywalled, plumbed, wired, and finished like a residential home. The result is a structure that looks like a large metal building from the outside but functions as a comfortable home inside — often with an attached workshop or equipment bay as part of the same footprint.
The most common layout in Middle Tennessee combines a 1,200–1,600 sq ft living area with an adjoining 1,200–2,400 sq ft shop or storage bay under the same roof. The contrast between the functional shop and the finished living space is part of the appeal.
Shell vs. turnkey — understanding your options
Shell package: We erect the structure — posts, trusses, metal roofing, metal siding, and exterior doors — and hand you a weathertight building. You manage or self-perform the interior work: insulation, framing interior walls, rough-in electrical and plumbing, HVAC, drywall, and finishes. This is the lowest upfront cost approach but requires significant owner involvement or coordination of multiple contractors.
Turnkey construction: We handle the complete project from slab to move-in, coordinating all trades. This is the highest-cost approach but gives you a fixed contract price, a single point of contact, and a predictable move-in timeline. For buyers who aren't experienced in construction management, turnkey is almost always the right choice — the cost of mistakes and delays in owner-managed projects routinely exceeds the cost difference between shell and turnkey.
Permits and inspections for barndominiums in Tennessee
In Tennessee, a barndominium with living quarters is permitted as residential construction — not agricultural. This means it must meet the Tennessee Residential Building Code, which includes requirements for insulation values, egress windows in bedrooms, smoke and CO detectors, electrical service size, and plumbing. Lawrence County and Giles County both require building permits for any living space structure.
You'll also need separate permits for the septic system (county health department) and, if applicable, a well permit. Getting these permits in order is one of the first steps — the timeline for septic system design and approval can be 4–8 weeks depending on the county health department's current workload.
Financing a barndominium in Middle Tennessee
Conventional mortgage lenders have historically been reluctant to finance barndominiums because of appraisal complexity. That's changing, but you should plan ahead. Options that work well in Lawrence and Giles County:
- Farm Credit Mid-America: Specifically structured to finance rural properties including barndominiums
- USDA Rural Development: For eligible buyers in rural areas
- Construction-to-permanent loans: From lenders familiar with non-traditional construction types
- Land equity as down payment: If you own the land free and clear, that equity can often serve as the construction loan down payment
