The build, by the numbers.

This 36′x40′x12′/9 A-frame colonial all-vertical barn features two 10′x10′ garage doors, a 36"x80" walk-in door, and vertical roofing and paneling. It also includes (4) 8x7′6" framed openings on the side.

It is close to square, which keeps the floor easy to divide instead of forcing everything into one line. No windows are specified, so daylight is something to raise at quote if you want it. Buyers most often order a 36′x40′x12′ barn for a hay barn with vertical drive-through center. Second most common: a wash rack.

What's it for

Same shell, very different jobs.

A 36′x40′ gets specified differently depending on what goes in it — door placement, openings, leg height, whether it closes in. Tell us the job and we'll spec it to that instead of handing you a blank form.

Questions

Good to know.

A specialist can walk you through this exact build over the phone in a few minutes.

A level spot is enough. Concrete, asphalt and compacted ground all work, and the matching anchors for all three ship with the building. Mark out the full 36′ x 40′ footprint and check it for level before delivery day — uneven ground is the one thing that reliably slows an install down.

It is the leg height, not the tallest point. 12′ runs from the base rail to the eave, where the roof meets the 40′ sidewall; the ridge is higher again because of the roof pitch. For anything driving into a 36′ x 40′ x 12′, the door opening is the real limit anyway.

This one is specified with (2) 10′x10′ Roll-Up doors. That is the opening itself, so measure whatever has to drive through against the door rather than against the 36′ width. Door sizes are not fixed — if what you are parking is tight, say so on the quote, because adding or resizing an opening up front is cheaper and cleaner than cutting one in later.

A framed opening is a door-sized gap with the structural framing already built around it and no door hung in it. You get the opening; you decide later whether to hang a door there or leave it open for drive-through access. This build is specified with (4) 8x7′6" framed openings.

Delivery and professional installation are both in it — the crew sets the 36′ x 40′ x 12′ on your site. What it does not cover is getting that site ready: leveling, and the concrete if you are pouring a pad. That happens before the crew arrives, by you or a local contractor. Treat $24,413 as the starting figure; options and your county's wind and snow certification move it.

Rust-through on the frame runs 20 years. Workmanship on the install runs 30 days. They are deliberately different lengths because they cover different risks — the steel of this 36′ x 40′ x 12′ degrading, versus how it went together on your site.

The 36′ x 40′ x 12′ shown here is one point on a range, not a fixed product. Width adjusts in 2-foot increments, length in 5-foot increments, leg height by the foot — so if you need a few more feet of 40′, that is a re-price rather than a different building.

We are building a barndominium and they delivered the shell on schedule. Our contractor said the framing was straighter than most stick-built shells he sees.

Loafing shed for the horses showed up exactly when they said it would. The crew leveled and anchored on uneven ground and didn't try to charge extra.

Hurricane-rated anchors and engineer-stamped drawings were ready when our county asked. Permit went through the first time.
