Do you build barndominiums under 5,000 sq ft?

No. We specialize in large structures starting at 5,000 sq ft — that is where our engineering, freight and crew economics are strongest.

Do you finish the interior?

No. We supply and, if you want, install the shell. Interior framing, mechanical and finishes are handled by your local builder.

Will it pass residential code?

Yes. Drawings are stamped to the residential or commercial code your county has adopted for the occupancy.

Can I add a porch and lean-to?

Yes — both are engineered into the frame so the roof line is continuous and there is no added seam.

Can a barndominium be financed like a house?

Many lenders treat it as residential construction when it is engineered and permitted as a dwelling. We provide stamped drawings your lender and jurisdiction can review.

Do you build the interior too?

We supply and install the engineered shell. Interior finish is typically handled by a local residential contractor working from our drawings.

What is a barndominiums steel building?

A barndominium is a steel building that combines living space with shop, garage or barn area under one engineered frame, usually with porches, lean-tos and a residential-grade facade. AMF supplies the shell and structure engineered for your local residential code, with framed openings for windows, doors and porch lines set during design.

What drives the price

The shell is a small share of a barndominium budget — interior finish, mechanicals and porches dominate. Getting window, door and porch framing right during design avoids expensive field modification.
