Recycled Component Canopy: Assembled from Old Steel and Second-hand Corrugated Sheets

Design an urban canopy assembled entirely from salvaged components. Show a roof carried on reclaimed steel sections of clearly mismatched profiles — old I-beams, a length of railway rail, a pair of scaffold tubes — bolted together through crude flitch plates, their original bolt holes and paint layers still visible and left unpainted. Detail the covering as a patchwork of second-hand corrugated metal sheets in different profiles and different faded colours: chalky blue, oxidised green, bare galvanised, each sheet showing its old fixing holes and edge damage, lapped over one another with no attempt to align the corrugation direction. Show a few translucent fibreglass sheets slotted into the patchwork where light is wanted, glowing yellow-green against the metal. Detail the structural logic as nonetheless clear and deliberate, so the assembly reads as designed reuse rather than as a shanty. Show the underside as the most interesting face, all the lap edges and old markings visible. Set it over a paved yard between brick warehouse buildings with weeds at the edges. Show hazy afternoon sun. Photorealistic, patchworked, faded colours and old steel, low three-quarter view.
