One Team From Bare Ground to Finished Building

A kit is a great option if you have a crew. But most owners would rather hand the whole thing to one company and get a finished building. That's our full build service: across Southwest Washington we handle design, stamped engineering, and construction — and in Cowlitz County we add site prep, foundation, and county permitting for a true bare-ground-to-finished turnkey, one point of contact and one number that covers it.

Because we're a DBA of a groundwork company, the part most builders sub out — the pad and drainage — is our specialty. In Cowlitz County we do that groundwork ourselves; across the rest of Southwest Washington we build your project and engineer it to your site, while site prep and permits are arranged on your end.

What to Expect Working With Us

What It Costs

A turnkey build adds site prep, foundation, and labor to the material package. We give a real number after a site review — no fake instant quotes, no online payment until you approve.

How We Respond

You talk to the people who build it. In SW Washington, site visits are typically within days — not a call center two states away.

When Something's Off

If your site drains poorly or needs a built-up pad, we say so up front and engineer for it — better solved on paper than after the posts are set.

Backed & Financed

WA-licensed (COLUMGI828N1), NFIB member, stamped engineering on every build. Financing available; pre-qualifying won't impact your credit.

How Your Build Comes Together

01
Design & Quote

Tell us your size, use, and county, or design it in the free 3D tool. We review your site before sending a real number.

02
Engineer & Permit

Stamped plans are produced for your site and load zone. In Cowlitz County we handle county permitting; elsewhere in SW Washington you or your contractor file with the stamped plans.

03
Site Prep

In Cowlitz County our groundwork crew handles drainage, pad, and foundation — the base the whole building depends on. Outside Cowlitz, site prep is arranged on your end.

04
Build

We raise it start to finish — posts, framing, roof, siding, doors — and hand you a finished building.

Build Services Across Southwest Washington

Our full build area covers Cowlitz, Lewis, and Clark County — Castle Rock, Longview, Kelso, Kalama, Woodland, Chehalis, Centralia, Vancouver, Battle Ground, and the towns between. Outside this area, we deliver pre-engineered kits across Washington, Oregon, and Idaho.

Where We Build

Building Services FAQs

Do you build outside Southwest Washington?

Full turnkey construction is limited to our Southwest Washington build area — Cowlitz, Lewis, and Clark County. Elsewhere in WA, OR, and ID we deliver a complete stamped kit for your own crew or contractor.

Do you handle site prep and permits, or just the building?

It depends where you are. In Cowlitz County we handle the whole scope — as a DBA of a groundwork company, drainage, pad, and foundation are in-house, and we handle county permitting too. Across the rest of Southwest Washington we build and engineer to your site, while site prep and permits are arranged on your end.

Can you build a kit I already bought?

Tell us the details and we'll let you know. Our builds are engineered as a package, so we'll confirm the plans and materials meet code for your site before we quote a build.

How is a turnkey build priced?

The material package plus site prep, foundation, and labor. We give a real number after reviewing your site, county, and load zone — there's no online payment, and we confirm the quote first.

Is financing available?

Yes. Financing is available and pre-qualifying won't impact your credit. Ask us when you request your quote.
