Shuttle Hangar

Shuttle hangar building, footprint exactly 12x12m, faceted low-poly barrel vault reaching exactly 6m at the crown, off-white hull panels on a gunmetal rib frame with a tall segmented door filling one 12m face and an astro orange threshold stripe.

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
