The build, by the numbers.

This 15x100x12′/10′ A-Frame Free Standing Lean-To building features all vertical paneling and roofing in Quaker Gray with Slate Gray trim, and includes delivery, installation, and warranties.

The run is 7 times the span here, so the floor works as a line of bays or a drive-through rather than one open room. Openings come framed and ready, with the doors chosen and priced separately when you quote it. Buyers most often order a 15′x100′x12′ building for a hay barn with vertical drive-through center. Second most common: saddle and tack storage.

What's it for

Same shell, very different jobs.

A 15′x100′ 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.

No concrete required. A 15′ x 100′ x 12′ cover anchors to concrete, asphalt or compacted ground, and the right anchors for whichever you have are included. What matters is that the 15′ x 100′ area is level and clear when the crew arrives.

On this 15′ x 100′ 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.

A framed opening is a door-sized gap with the structural framing already built around it and no door hung in it. You get the opening; you decide later whether to hang a door there or leave it open for drive-through access. This build is specified with (2) 22′x10′ frame Outs, (3) 101′x10′ frameouts.

$30,200 covers the building, the delivery and the install crew. It does not cover site work — leveling the 15′ x 100′ 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 15′ x 100′ 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 15′ x 100′ x 12′ 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.

Frame gauge is structure, panel gauge is skin. On this 15′ x 100′ 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.

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.
