Centered on a horigotatsu, this Zen dining room features a sunken seating well in charcoal microcement with a light solid-wood table. Lime plaster walls and exposed dark timber beams anchor the space, while clerestory windows and a shoji-style screen open to a rain-washed stone garden. Warm perimeter LEDs skim the platform and limestone floor, emphasizing natural textures, restrained lines, and a calm palette punctuated by indigo cushions.
