The build, by the numbers.

This 20′x21′x11′ fully enclosed A-Frame vertical roof garage features a 10′x10′ garage door and a walk-in door. It is perfect for storing vehicles, tools, or other equipment.

The near-square footprint divides evenly, so you are not committed to a single long lane. No windows are specified, so daylight is something to raise at quote if you want it. 20′x21′x11′ is a size that usually goes up as self-storage style locked dry storage. Second most common: a loading bay.

What's it for

Same shell, very different jobs.

A 20′x21′ 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 21′ footprint, be level, and be cured before delivery, because the walls of a 20′ x 21′ x 11′ 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.

Eave height. On a 20′ x 21′ x 11′ that means 11′ of straight wall before the roof starts to pitch up, so usable height at the walls is 11′ and the center is taller. Measure your equipment against the eave figure if it sits near a sidewall.

This one is specified with (1) 10′x10′ 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 A-Frame vertical roof garage. 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.

$7,780 covers the building, the delivery and the install crew. It does not cover site work — leveling the 20′ x 21′ 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.

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 20′ x 21′ 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 20′ x 21′ x 11′ 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.
