LONGPORT

Black Walnut

LONGPORT settles into a soft taupe walnut palette with gentle gray undertones and relaxed grain movement. Its surface feels calm and natural, offering a lighter, more muted walnut finish compared to deeper brown finishes. For residential interiors, offices, wall cladding, ceilings, and refined millwork, LONGPORT brings a graceful wood tone that feels warm, approachable, and easy to live with.

Grade Selection—Same Performance, Different Expression

LONGPORT is offered in two carefully curated grades to suit a range of design aesthetics. Select Grade emphasizes tonal uniformity and a cleaner appearance, while Character Grade showcases the inherent beauty of European White Oak through knots, grain variation, and other natural features. Regardless of grade, each plank is crafted to the same performance standards—the difference lies solely in the visual character of the wood.

Coordinated Stair & Trim Solutions

A cohesive interior begins with thoughtful material coordination. Extending the flooring specification across stairs, transitions, and architectural trim creates visual continuity throughout a space while reinforcing a unified design aesthetic.

Custom stair and trim components can be fabricated to complement the flooring specification, ensuring consistency in species, texture, color, and finish across all interior elements. Coordinating these components through a single source also helps streamline procurement, simplify project coordination, and minimize material matching challenges from specification through installation.

Available profiles include stair treads, risers, nosing, transitions, wall base, and thresholds. By sourcing flooring and complementary components together, design teams, contractors, and installers can achieve a more efficient workflow and a seamless finished installation.
