Multi-Storey Ward Block

12x8m hospital ward wing on the 2m grid, three floors at exactly 3m each with the roof line at 9m and a low parapet above, banded ribbon windows, flat side walls exactly on the footprint edges so copies butt into a longer wing, and a floor-count knob.

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
