Same camera position: Family Living area looking toward a U-shaped staircase, 6m ceiling height, cantilevered treads from a central spine wall. Treads in dark charred oak with warm white LED strip (3000K) concealed under each tread's nose, glowing continuously. Spine wall and all surrounding walls finished in off-white textured plaster (micro-cement / troweled stucco with subtle shadows). Ceiling: deep recessed adjustable spots (black trim) washing light down the fluted texture. No chandelier. Under the staircase landing, a glazed courtyard with a minimalist Zen garden: fine white gravel, a single rounded basalt stone, a small preserved moss island. Frameless glass balustrades. Floor in living area: polished dark grey micro-cement. Night scene, ambient warm interior light, blue hour outside through unseen windows. Photorealistic, cinematic contrast, 8K.
