The build, by the numbers.

This fully enclosed 18′x20′x9′ A-frame vertical roof garage features a 14g steel frame and 29g panels, with a 9′x8′ door. Ideal for secure vehicle storage or workshop use.

It is close to square, which keeps the floor easy to divide instead of forcing everything into one line. There is no walk-in door in this configuration, which is the usual first addition if you plan to work inside. 18′x20′x9′ is a size that usually goes up as a light manufacturing floor with utility runs. Second most common: fleet parking.

What's it for

Same shell, very different jobs.

A 18′x20′ 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 18′ x 20′ footprint, be level, and be cured before delivery, because the walls of an 18′ x 20′ x 9′ 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.

It is the leg height, not the tallest point. 9′ runs from the base rail to the eave, where the roof meets the 20′ sidewall; the ridge is higher again because of the roof pitch. For anything driving into an 18′ x 20′ x 9′, the door opening is the real limit anyway.

This one is specified with (1) 9′x8′ 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.

The sheet for this build states fully enclosed A-Frame vertical roof garage. 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.

$6,535 covers the building, the delivery and the install crew. It does not cover site work — leveling the 18′ x 20′ area, or pouring a slab if this one is going on concrete. Those happen before install day. Options and local wind and snow certification are the two things that move the number.

Two covers on two clocks. The steel frame under this 18′ x 20′ x 9′ 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 20′ x 9′ 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 20′, 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.
