Who We Are
Based in Seattle, Coriolis is led by Shawn, a master craftsman who began as a wood turner and never stopped chasing the elegance of movement. Since 1978, he has built museum-grade staircases across three continents, with extensive work throughout Hawaii and the Pacific Northwest. A former president of the Stairbuilders and Manufacturers Association, Shawn also holds Architectural Educator Credentials with the AIA, where he leads continuing education sessions for architecture firms across the country in the stair design category.
At Coriolis, we approach the stair early and integrate it deeply. Architecture, structure, ergonomics, and code are resolved with the same respect we give to proportion and line. Clients bring us in for our judgment and solutions.

Consulting
Finding a competent stair builder is difficult. Finding one who will actually talk to you is rarer. Finding someone with the availability, skill, and range to execute a truly custom staircase is nearly impossible.
If Coriolis cannot take on your project within your timeline, we do not leave you stranded. We connect you directly to the best stair builders in the country.
As former President of the Stairbuilders and Manufacturers Association, Shawn is deeply embedded in the industry. He knows who excels at what, who operates at the highest level, and who can be trusted to deliver. When he calls, they answer.
Glass Stairs
For projects that call for transparency, strength, and light, we design structural glass systems that redefine what a staircase can be.
Wood Turning
The origin of Coriolis' craft, where the discipline of the lathe meets the poetry of form. Every newel, rail, and volute is shaped to invite the hand.
Where We Work
Coriolis operates from Seattle, a city defined by creativity, precision, and design integrity. Our work spans the Pacific Northwest, Hawaii, and Alaska, with select commissions across the United States, Europe, and Asia. Whether the project is a waterfront estate, a historic renovation, or a destination property abroad, our approach remains the same — to build staircases that belong to their space, their architecture, and their story.
Our Philosphy
Behind every staircase is the belief that beauty has the power to lift us.
