A serene laundry pairs light-wood shoji screens with a built-in front-loading washer set along tatami mats. A honed gray-stone sink block with a matte black tap extends into a slim indoor rill lined with river pebbles and soft moss. Large beige wall tiles and a tall window deliver diffused daylight, while a rice-paper lantern adds a warm glow. Joinery and screens create tidy symmetry and conceal clutter, expressing Japanese Zen utility.
