"Model a realistic architectural intervention on an urban site consisting of a fixed, F-shaped concrete wall system combined with dynamic, pivoting panels and stepped seating platforms. The base wall layout measures 40 meters tall (vertical leg) and 32.5 meters wide (horizontal extent), with indents and projections forming a capital 'F' shape in plan. All dimensions are in meters. The wall thickness is 0.4 meters with chamfered corners (2 cm bevel), made of lightly textured raw concrete (board-form finish), slightly weathered and with graffiti remnants in certain patches."
