The build, by the numbers.

This 30′x40′ carport with a 12′ eave, vertical roof, and horizontal side paneling is finished in evergreen. It comes with a 30-day workmanship warranty, a 20-year rust-through warranty, and includes delivery and installation.

Nothing is framed for drive-in access as listed, so an opening or overhead door is sized at quote. 30′x40′x12′ is a size that usually goes up as a tailgate-friendly cover for the back patio. Second most common: livestock shade.

What's it for

Same shell, very different jobs.

A 30′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.

For a closed building this size, yes. The pad wants to match the 30′ x 40′ footprint, be level, and be cured before delivery, because the walls of a 30′ x 40′ x 12′ seal down onto it and the door track depends on it being flat. Pour it yourself or have a local contractor do it ahead of the install date.

On this 30′ x 40′ x 12′ the 12′ is eave height — base rail up to where the roof meets the sidewall, which is the height of the legs. The peak sits higher because the roof is pitched. Check clearance against the eave and against the door opening, never against the peak.

The sheet for this build states (2) sides closed. Anything about how it closes in — which ends, which sides, where the doors land — is settled on the quote, so if you need a different arrangement it does not have to be a special order.

Delivery and professional installation are both in it — the crew sets the 30′ 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 $9,185 as the starting figure; options and your county's wind and snow certification move it.

The 20 years figure is rust-through on the frame, which is the structural cover and the one that matters over the life of a 30′ x 40′ building. Separately, the install itself is warranted 30 days, so anything that looks wrong when the crew leaves should be raised inside that window.

This page prices the 30′ x 40′ x 12′ as built, but width moves in 2-foot steps, length in 5-foot steps and leg height in 1-foot steps. Tell us the footprint you actually need and we price that build instead.

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.
