The build, by the numbers.

This 18′x31′x7′ utility carport features a 10′ enclosed section, one 8′x7′ roll-up door, and a walk-in door. It is perfect for housing vehicles or securing valuables with customizable options.

No windows are specified, so daylight is something to raise at quote if you want it. The most common thing we quote an 18′x31′x7′ for is an rv pad with full walk-around clearance. It also gets ordered for 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.

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 18′ x 31′ 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. 7′ runs from the base rail to the eave, where the roof meets the 31′ sidewall; the ridge is higher again because of the roof pitch. For anything driving into an 18′ x 31′ x 7′, the door opening is the real limit anyway.

This one is specified with (1) 8′x7′ roll up door. That is the opening itself, so measure whatever has to drive through against the door rather than against the 18′ 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.

It can be. Sides, ends or both can be panelled on an 18′ x 31′ x 7′, and that decision belongs on the quote rather than afterwards — panels fitted at the factory land better and cost less than a retrofit.

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 $6,223 as the starting figure; options and your county's wind and snow certification move it.

Two covers on two clocks. The steel frame under this 18′ x 31′ x 7′ carries a 20 years rust-through warranty. Workmanship is covered 30 days from installation — the window for raising anything the crew got wrong on the day. Corrosion is the long one; install quality is the short one.

The 18′ x 31′ x 7′ 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 31′, 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.
