Architectural Distinction

Classical Four-Panel Symmetry in Pure Solid Alder

Curated by CHAN TAM WOODEN DOOR, the Classic 4-Panel Interior Slab Door showcases the refined, fine-grained warmth of genuine timber. Crafted entirely from 100% solid Pacific Alder—free of composite wood, particleboard, or synthetic MDF core—this door delivers substantial natural heft, quiet acoustic isolation, and crisp architectural shadow lines. Delivered completely unfinished, it offers an uncompromised custom canvas for fine residential developments and hospitality projects.
