Barndominium Builders
in Houston, TX

How much does a barndominium cost to build near Houston?

There is no flat rate, and two builds on two pieces of land price very differently. Six things move the barndominium cost the most:

• Shell only, dried in, or finished out
• Frame size, clear span and the design wind speed at your address
• Slab design once the soil report comes back
• Number and size of overhead doors, windows and porches
• Insulation and interior framing
• Site access, septic, well and floodplain fill

Red iron or post frame: which one should I build on acreage?

Red iron is welded plate and beam, engineered as a structure and bolted to an anchor bolt pattern in the slab. Post frame is wood columns set on brackets or in the ground. Near the coast, red iron is the easier building to engineer for wind, to insure, and to get a lender comfortable with. It also clear-spans 40 to 80 feet, so nothing sits in the middle of your shop. We build red iron only. See structural steel for how the frame is detailed and steel erection for how it goes up.

Do I need a permit for a barndominium outside Houston city limits?

Almost always, and it depends on the county. Waller, Montgomery, Brazoria, Liberty and Fort Bend each run their own permit, floodplain and septic offices, and unincorporated land still has flood rules and elevation requirements. Plan on three approvals:

• A building or development permit from the county
• An OSSF (septic) permit, which needs a site evaluation first
• A floodplain determination, and an elevation certificate if you are in a mapped zone

Can I get a construction loan and an appraisal on a barndominium?

Yes, and it is easier than it was five years ago. Most buyers use a construction-to-permanent loan and draw against it as the slab, shell and interior finish. Two things make the file go smoothly: engineered, sealed plans with wind calculations, and a build that reads as a home. Appraisers want comparable sales, so a finished living area with normal residential rooms appraises better than an open shop. We give your lender the plan set, the engineer letters and a dated draw schedule up front.

How do you insulate a barndominium for Houston humidity?

Closed-cell spray foam applied straight to the roof and wall panel is the standard here. Steel panel is cold in the morning and warm by noon, and Gulf air condenses on it, so a fiberglass blanket alone leaves you with drips and rust. Foam stops the condensation, seals the panel laps, and stiffens the wall. We usually run about 3 inches at the roof and 2 inches at the walls, then frame interior walls inside it. Your HVAC contractor will size a smaller unit as a result.

Can you build just the shell and let me finish the inside myself?

Yes. A lot of owners buy the slab, frame, panel, doors, windows and foam from us, then finish the inside themselves or hire their own trades. We hand it off dried in, square and inspected, with the plumbing and electrical sleeves already in the slab where your plans call for them. If you decide later that you want the shop side only, our shops and garages page covers that build, and concrete slabs covers the floor under it. Call (832) 576-3278 or send us your plans and we will price both ways.
