The build, by the numbers.

This 18′x31′ open carport with a 7′ eave height has a regular roof design and is pictured in evergreen with white trim. It includes delivery, installation, and warranties covering workmanship and rust-through.

Nothing is framed for drive-in access as listed, so an opening or overhead door is sized at quote. The most common thing we quote an 18′x31′x7′ for is an rv pad with full walk-around clearance. Second most common: hay equipment cover.

What's it for

Same shell, very different jobs.

A 18′x31′ 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.

No concrete required. A 18′ x 31′ x 7′ cover anchors to concrete, asphalt or compacted ground, and the right anchors for whichever you have are included. What matters is that the 18′ x 31′ area is level and clear when the crew arrives.

Eave height. On an 18′ x 31′ x 7′ that means 7′ of straight wall before the roof starts to pitch up, so usable height at the walls is 7′ and the center is taller. Measure your equipment against the eave figure if it sits near a sidewall.

Yes. The 18′ x 31′ x 7′ is listed here as an open structure, but whether it closes in is settled at quote — along with door placement, openings and leg height. Doing it at order time is cheaper and cleaner than adding panels to a building that is already standing.

Delivery and professional installation are both in it — the crew sets the 18′ x 31′ x 7′ 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 $3,065 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 an 18′ x 31′ building. Separately, the install itself is warranted 30 days, so anything that looks wrong when the crew leaves should be raised inside that window.

It is not a fixed size. Starting from this 18′ x 31′, width changes in 2-foot steps and length in 5-foot steps, and the 7′ legs move a foot at a time. Give us the size you need and we quote that one.

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.
