The barn-style custom home, reimagined for Florida.
Steel-frame durability, open floor plans, industrial character, and hurricane-code construction. The barndominium approach delivers a custom home for less per square foot than traditional stick-built — with fewer maintenance headaches over time.
Everything from site to move-in, handled in-house.
Barndominiums are simpler than traditional homes in some ways and more complex in others. Our team handles every step — site prep through interior finish — so you get a truly turn-key custom home.
Site prep & foundation
Land clearing, grading, and monolithic slab or stem-wall foundation matched to Brevard County soil and drainage.
Engineering & permits
Full structural engineering for the steel frame, Brevard County permits, and any environmental review required for your specific parcel.
Steel-frame construction
Pre-engineered steel building or custom red-iron frame, sized and rated for Florida hurricane winds. Longer spans, fewer interior columns.
Insulation & climate
Spray foam or batt insulation designed for steel-frame buildings. Ducted HVAC or mini-splits — sized for the open-plan cooling load.

Interior walls, ceilings, doors, and any second-story or loft framing inside the steel envelope.
Finishes & fixtures
Flooring, kitchen, bathrooms, trim, paint — all the interior finish work of a normal custom home, done to your spec.
Exterior finish & site
Siding or metal panel finish, roof, gutters, driveway, and yard grading. Move-in day, the property is complete.

Barndominium questions, answered honestly.
What is a barndominium?
A barndominium — sometimes called a "barndo" — is a residential home built with a metal or steel-frame structure, typically featuring open floor plans, high ceilings, and industrial-style character. Originally inspired by barn architecture (hence the name), modern barndominiums range from simple homes to luxury custom builds with the durability advantages of steel-frame construction.
How much does a barndominium cost in Brevard County?
Real 2026 ranges: shell + basic interior $180k–$350k for 1,500–2,500 sq ft. Full custom home $350k–$700k for 2,000–3,500 sq ft. Premium/estate builds $700k–$1.5M+ for larger footprints. Cost per square foot is typically 10–25% less than traditional stick-built homes at similar quality levels, especially at larger sizes.
How long does construction take?
Shell + basic interior: 5–7 months from breaking ground to move-in. Full custom: 7–10 months. Premium/estate builds: 10–14 months. Add 2–4 months upfront for design, engineering, and permitting before construction begins. Weather delays are minimal since the steel shell goes up fast.
Are barndominiums hurricane-code compliant in Brevard?
Absolutely. In fact, properly-engineered steel-frame buildings often exceed Florida hurricane code requirements. We use pre-engineered building systems or custom red-iron frames rated for Brevard's wind zones (which include 130–150+ mph design winds depending on your specific location). Every plan is engineer-stamped before permitting.
Can I get a mortgage on a barndominium?
Yes — but with fewer lenders than traditional homes, and often better rates with local Florida banks who understand the barndominium market. Cash construction with permanent-loan refinance is common. We can point you toward lenders who work with barndominiums regularly. Appraisals have improved dramatically as barndominiums have become mainstream.
Do I need to own the land first?
Yes — we build on your parcel. We can help you evaluate land during the feasibility consultation to ensure it's zoned for residential, has utility access (or can support well/septic), and meets Brevard County requirements. We do not sell land or handle land acquisition.
