apartment building 3d model

Create a game-ready low-poly 3D model of a 5-story Soviet-era apartment block (Khrushchevka) matching the reference image. The building is a long rectangular slab, ~5 floors, with a weathered beige plaster facade (patchy repairs, stains), flat roof with parapet and a row of short red chimneys/vents, and many small metal balconies distributed along the facade (some with simple rails, some slightly different). Include a few vertical stairwell window strips and simple entrance doors at ground level. Overall look: old, worn, post-Soviet residential building, realistic proportions.
