What's it for
Same shell, very different jobs.
A 20′x40′ 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.

Questions
Good to know.
A specialist can walk you through this exact build over the phone in a few minutes.
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 20′ x 40′ footprint and check it for level before delivery day — uneven ground is the one thing that reliably slows an install down.
On this 20′ x 40′ x 12′ the 12′ is eave height — base rail up to where the roof meets the sidewall, which is the height of the legs. The peak sits higher because the roof is pitched. Check clearance against the eave and against the door opening, never against the peak.
This one is specified with (3) 10′x10′ roll-up doors. 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.
$15,330 covers the building, the delivery and the install crew. It does not cover site work — leveling the 20′ x 40′ 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 40′ 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 20′ x 40′, width changes in 2-foot steps and length in 5-foot steps, and the 12′ legs move a foot at a time. Give us the size you need and we quote that one.
Frame gauge is structure, panel gauge is skin. On this 20′ x 40′ the frame is 14-gauge galvanized steel and the panels are 29-gauge steel. Because the scale runs backwards, the smaller number is the thicker steel — which is why the frame figure is the one worth checking when two quotes look the same.

Real, verified Google reviews from owners who bought their building from us, straight from our business profile.
View all reviewsWe 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.
