The build, by the numbers.

This 28′x45′x12′ fully enclosed vertical gambrel barn offers spacious storage with (4) 10′x8′ framed openings(2 per End), (1) 6′x7′ framed opening, (2) walk-in doors, and (5) 8′x9′ framed openings on the side of each lean-to for light and air.

The openings are framed but the doors themselves are not part of it, so door type and operation get specified at quote. 28′x45′x12′ is a size that usually goes up as a three-stall horse barn with center aisle and tack room. It also gets ordered for small livestock.

What's it for

Same shell, very different jobs.

A 28′x45′ 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 28′ x 45′ 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 45′ sidewall; the ridge is higher again because of the roof pitch. For anything driving into a 28′ x 45′ x 12′, the door opening is the real limit anyway.

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) 10′x8′ framed Openings, (1) 6′x7′ framed Opening, (5) 8′x9′ framed openings.

Delivery and professional installation are both in it — the crew sets the 28′ x 45′ 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 $39,040 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 28′ x 45′ x 12′ degrading, versus how it went together on your site.

It is not a fixed size. Starting from this 28′ x 45′, width changes in 2-foot steps and length in 5-foot steps, and the 12′ legs move a foot at a time. Give us the size you need and we quote that one.

Frame gauge is structure, panel gauge is skin. On this 28′ x 45′ the frame is 14-gauge galvanized steel and the panels are 29-gauge steel. Because the scale runs backwards, the smaller number is the thicker steel — which is why the frame figure is the one worth checking when two quotes look the same.

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.
