木型枠の痕跡と鉛封孔：打ち放しコンクリートの誠実な表面

Design a concrete wall in the manner of Louis Kahn where the record of its own making is left entirely visible — plywood panel joints, the grain of the boards, the pour lines between lifts, and the tie holes deliberately filled with lead plugs. Compose a large flat expanse of warm grey concrete with a regular grid of chamfered panel joints, small dull lead discs at each tie, a slight colour variation between pours, a plain travertine plinth below, low raking sun revealing every texture, close frontal view, 50mm lens, architectural photography, ultra photorealistic, 8K
