Sandpoint, Idaho · General Contractor
Mountain Country. Built to Endure.
ONYX Construction
Rugged country deserves refined building.
North Idaho asks a lot of a building — heavy snow, steep ground, long winters, and views worth every square inch of glass. ONYX builds for all of it, pairing durable construction with clean, timeless design and a process built on straight answers.

Who We Are
A builder you can count on, start to finish.
ONYX Construction is a Sandpoint-based general contractor. We're small enough that you'll know the people building your project by name, and capable enough to deliver to the exacting standards of federal work.
Whether it's a lake home on Pend Oreille, a new shop for your business, or a federal facility for the Department of Defense, the approach is the same: plan carefully, communicate honestly, and build it right the first time.
How We Build
A clear process,
no surprises.
Every ONYX project follows the same four steps, with one point of contact from your first conversation to the final walkthrough. You always know what's happening and what comes next.
- 01
Listen
We start on your land, learning how you want to live or work there and what the site can support.
- 02
Plan
Design coordination, engineering, budgets, and permits, organized into a clear, honest plan.
- 03
Build
Skilled crews, tight schedules, and regular updates so you always know where things stand.
- 04
Stand Behind It
A thorough walkthrough, a clean handoff, and a team that answers the phone long after move-in.
The Work
Our work, up close.
Timber, stone, and glass, put together with care. We sweat the details most people never notice, because they're the ones you'll live with every day.
