H-Shaped Barndominium Cost: What The Shape Adds
Finished barndominiums run $80–$120 per square foot at a standard finish nationally. An H-shaped plan belongs at the top of that range, and the reason is exterior wall.
Cost By Plan Size
| Plan Size | Plans | Shell Only ($30–$50) | Standard Finish ($80–$120) | High-End ($150+) |
|---|---|---|---|---|
| 3,000–3,999 sq ft | HB-40503, 40505, 40506, 40507, 40508, 40509, 40511 | $90,000 – $200,000 | $240,000 – $480,000 | $450,000+ |
| 4,000–4,999 sq ft | HB-40501, 40502, 40504, 40510 | $120,000 – $250,000 | $320,000 – $600,000 | $600,000+ |
Figures cover the heated living area only. Porches, breezeways and garages price closer to shell rates, because they take no insulation, drywall or HVAC. Land, site work, septic and utilities are separate.
Why An H Costs More Per Square Foot
Take HB-40508. Its two 22' × 60' wings and 21' × 11' foyer enclose about 2,870 square feet inside roughly 348 feet of exterior wall. A plain 48' × 60' rectangle encloses the same 2,880 square feet with 216 feet.
The H has about 60% more wall to frame, sheathe, insulate, side and trim. It also has four roof valleys where the bar meets the wings, and a dozen corners to flash instead of four.
- Heating and cooling: more wall means more surface losing heat, for as long as you own the house. Most H plans are best served by two HVAC zones, one per wing.
- Roofing: valleys are where roofs leak. Use a roofer who has flashed metal valleys before.
- Foundation: more perimeter means more footing and more edge insulation on a slab.
What you get for it is light and air on three sides of nearly every room, and real acoustic separation between the two halves of the house.
Where To Save
- Pick the narrowest plan that works. HB-40508 and HB-40511 have the shortest bars.
- Keep the porches simple. Shed roofs off the wings cost far less than separate gabled porch structures.
- Build the shell as a kit. Each wing is a standard clear-span rectangle, which is where steel and post-frame kits are cheapest.
Cost figures are national planning estimates and vary with region, site conditions, material prices and finish selections.
