素材実験ブックウォール：コンクリート打ち放しと真鍮象嵌

Show a full-height bookwall in a Taiwanese home built as an exercise in two materials meeting precisely. Cast the structure in board-formed concrete with the timber grain and board joints clearly imprinted and the tie holes deliberately arranged on a regular grid. Inlay slim unlacquered brass strips, 8 millimetres wide, flush into the concrete along every shelf edge, so the horizontals read as thin warm lines against the grey mass. Show the brass already darkening unevenly where hands have touched it. Fill the shelves with real books stacked both upright and flat, a few ceramics and one framed photograph leaning rather than hung. Light with a slim linear fitting recessed behind each brass line, washing down onto the books. Keep the rest of the room quiet — a dark stone floor, a single leather armchair, a simple floor lamp. Show low warm evening light so the concrete texture and the brass glow both read. Photorealistic, precise craft against raw material, eye-level view straight at the wall.
