The build, by the numbers.

This 20′x20′x10′ steel garage is fully enclosed with three roll-up doors, a walk-in door, and a window. It offers secure, spacious storage for vehicles, tools, and valuables.

It is close to square, which keeps the floor easy to divide instead of forcing everything into one line. The most common thing we quote a 20′x20′x10′ for is boat and trailer winter storage with year-round shop space. It also gets ordered for tractor parking.

What's it for

Same shell, very different jobs.

A 20′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 20′ x 20′ footprint, be level, and be cured before delivery, because the walls of a 20′ x 20′ x 10′ 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. 10′ 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 a 20′ x 20′ x 10′, the door opening is the real limit anyway.

This one is specified with (2) 8′x7′ roll up Door, (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 20′ 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. It also carries (1) Walk-In door. 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 20′ x 20′ x 10′ 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 $9,510 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 20′ x 20′ x 10′ 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.

It is not a fixed size. Starting from this 20′ x 20′, width changes in 2-foot steps and length in 5-foot steps, and the 10′ 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.
