A raised tatami platform anchors this Zen media room, edged in cast concrete above a lit bed of river stones and sand. Earthen plaster and exposed timber frame a low wood table over a sunken footwell, while washi lanterns and a folding shoji screen soften the light. Sage tatami, warm woods, and soft whites set an earthy palette, as discreet downlights and a lit wall niche shape a meditative, distraction‑free space.
