Serene and functional, this Japanese Zen mudroom pairs smooth plaster walls with a speckled terrazzo floor inlaid with pebbles and shells. A floating solid-wood bench glows with concealed LED light while a copper rain chain falls from a wood-trimmed skylight into a river-stone basin; a round porthole window, bamboo panel in black steel, and a ceramic pot with fern complete the meditative entry. A slim black-framed glass wall opens the space to the landscape.
