Solid Structures

Solid Structures is a post-frame builder headquartered in Spokane, Washington, with multiple offices in the state and a service area covering Washington, Idaho, and Montana, with Oregon listed as coming soon. The company builds barndominiums, residential shops and garages, commercial facilities, and other post-frame and pole buildings. Materials and systems named on its site include Permanent Post Systems, Timber Technologies glulam columns, American Lumber, and Miramac Metals, and the company is connected to Pole Building Kits USA.

Projects can start in a 3D building visualizer, then move through plans, engineering, and construction. Solid Structures backs its buildings with a lifetime warranty, is BBB accredited, and holds membership in the National Frame Builders Association. Customer testimonials on the site describe construction crews completing projects on schedule, and the company operates from several Washington locations rather than a single office.

The site does not spell out a fixed shell versus turnkey package structure, so buyers should confirm finish-out scope during the quoting stage. For barndominium projects in the Inland Northwest, Solid Structures pairs named engineered-post and lumber suppliers with an established regional footprint across 3 states.
