Whole Log Selection

Precision Milling

Hand-Cut Joinery

Hand-Planed Finish

We personally select each log from sustainable Pacific Northwest mills, ensuring optimal grain structure and character for its intended purpose.

Logs are milled in-house to exact specifications, carefully preserving grain continuity and minimizing waste for each unique commission.

Traditional mortise and tenon joints are hand-cut, eliminating the need for synthetic fasteners and allowing wood to move naturally with seasons.

Surfaces are hand-planed to achieve a tactile, unlacquered finish, revealing the wood's natural depth and inviting touch.

Material Integrity

Sourcing Unlacquered Timber

Our commitment begins at the source. We work directly with local mills in Oregon and Washington, selecting specific white oak and walnut logs known for their density and unique grain. This ensures full traceability and superior material quality.

Request Material Sample Sets

For architects and designers, we offer curated material sample sets of our signature unlacquered white oak and grain-matched walnut. Experience the tactile difference firsthand.
