Riveted boiler hall

8x4m footprint single-storey workshop hall with a 3m wall line and a swelling barrel roof of riveted boiler sheet above it, flat party walls exactly on the footprint edges so copies butt into a terrace, a big timber cargo door on the 4m gable end.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
