A Garage Built for Real Storage
A pole barn detached garage gives you the door heights, ceiling clearance, and shop space a tract-home garage never will — engineered for Pacific Northwest snow and wind. Take a kit anywhere in WA, OR, or ID, or have our crew build it in Southwest Washington.
Not a Catalog Box
Most attached garages were sized for a sedan and a lawnmower. A post-frame detached garage is designed around what you actually park and store — a lifted truck, a boat, an RV, a workbench, an upstairs loft. Clear-span framing means no interior posts eating your floor, and a lower cost per square foot than stick-built without giving up strength.

Single & Two-Bay
Everyday parking with room to actually walk around the vehicle, plus wall space for storage and tools.
Three-Bay & Shop Combo
Park on one side, work on the other — a heated shop bay with the doors and clearance a project needs.
Tall-Door RV Garage
Extra eave height and oversized doors that clear a motorhome, boat on a trailer, or dually with a canopy.
Garage with Loft
Add overhead storage or a bonus space above the bays — engineered into the design from the start.

We assess drainage and pad before the slab — a garage is only as solid as the ground under it.
WA-licensed (COLUMGI828N1), stamped engineering. Financing available; pre-qualifying won't impact your credit.

All Building OptionsPole Barn Garage FAQs
How big can a detached pole barn garage be?
From a single bay up to large multi-bay shops with tall RV doors. Clear-span post-frame framing lets us go wide without interior posts, so you get usable floor at any size. We size the structure to your snow and wind load.
Can I add a shop or loft to the garage?
Yes. Heated shop bays, workbench walls, and overhead lofts are all designed into the plan from the start — not bolted on later.
Do garage kits include the doors?
Yes. Kits include garage doors, man doors, and Low-E argon windows sized to your design, plus the full trim and fastener package. Concrete slab and site prep are arranged separately or bundled into a turnkey build.
Kit or full build?
Either. A kit gives you upfront pricing to DIY or hand to a contractor. In Southwest Washington our crew can build it start to finish, including the slab and site prep.
