What we build across Oregon and Washington.
49 years building across Oregon and Washington in both post-frame and steel-frame (red-iron) construction. The list below covers every building type we regularly take on, in whichever framing fits the project. Each page goes into who it's for, what's typically included, and how to start a quote.
Steel Frame Buildings
Steel-frame (red-iron) construction for the projects where steel is the right call — very large industrial spans, tall eaves, and heavy-use commercial buildings. Miner builds in steel and post-frame both.

Shops & Garages
Single-bay shops, multi-bay garages, and hobby workshops on rural acreage and suburban lots.

Agricultural Buildings
Ag-exempt and county-permitted agricultural structures, from open hay covers to fully enclosed equipment buildings.

Equestrian Buildings
Covered riding arenas with wide clear-span interiors, stall barns, and the run-in and tack-room wings that go with them.

Commercial Pole Buildings
Commercial post-frame structures for businesses, subcontract work for general contractors, and prevailing-wage public projects.

Storage Buildings
Simple, durable storage shells from open-sided RV cover to fully enclosed multi-bay warehouse.

Barndominiums
Living quarters joined to a working shop or barn in one post-frame envelope — faster and lighter than building each separately.

Three things that apply to every project
Experience
Family-owned since 1977
49 years of post-frame and steel building construction across the Pacific Northwest. Repeat customers across two-plus decades.
Trustworthy
In-house crews
Foremen and framers are MPB employees, never subcontracted. The hands that draw your building are the hands that build it.
Efficient
From quote to finished building
A clear path: project review, written bid with base + itemized additions, scheduled build, project closeout. See the process →
