The build, by the numbers.

30′x45′x12′ A-Frame Vertical Garage features vertical roofing and paneling. It includes two lean-tos for extra coverage, a 12′x12′ garage door, and a 36"x80" walk-in door.

No windows are specified, so daylight is something to raise at quote if you want it. The most common thing we quote a 30′x45′x12′ for is a two-car daily-driver garage with a workbench wall. It also gets ordered for tool and parts storage.

What's it for

Same shell, very different jobs.

A 30′x45′ 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.

Good to know.

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 30′ x 45′ footprint and check it for level before delivery day — uneven ground is the one thing that reliably slows an install down.

On this 30′ x 45′ 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 lean-to is a lower roof section attached along a sidewall — it adds covered space without widening the main building's span, which is why it is a cheaper way to buy square footage. This build is specified with (2) 12′x40′x10′ Lean-To.

Yes to delivery and install, no to site prep. The crew brings and erects the 30′ x 45′ x 12′; you provide a level, cleared spot for it to land on. The price shown is a start point rather than a final invoice, because certification requirements and any added doors or openings change it.

Two covers on two clocks. The steel frame under this 30′ x 45′ x 12′ 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 30′ x 45′, 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.

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.

Priya & Dave L.
Bend, OR
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.
