Alder Warmth Meets Soft, Silhouetted Light

This barn door marries knotty alder’s organic texture with satin-frosted panels that bathe rooms in a gentle glow. The refined 3‑lite symmetry creates a crisp architectural rhythm that feels tailored yet inviting. Style it with matte-black hardware and layered neutral textiles to balance rustic character and contemporary polish. It’s a quietly luxurious statement that reshapes passageways into moments of design.
