Anchored by a smooth concrete floor, this Zen mudroom centers a circular recessed moss garden edged in concrete and black gravel. A granite step rises to a tatami threshold screened by a linen noren, alongside a solid wood bench lit by a washi paper lantern. Textured plaster walls and a lattice-front wood cabinet with a single ceramic vase express wabi-sabi restraint. A clerestory with vertical slats casts striped daylight, warming natural wood tones and calm shadows.
