neoclassical building 3d model

Create a detailed 3D model of a neoclassical building from the reference image. The structure is rectangular and symmetrical with a front colonnade of tall Corinthian columns supporting an entablature and flat roof with balustrade. The facade is light stone (off-white) with large arched windows between columns and rectangular windows on the side sections. Maintain accurate proportions, column spacing, and depth. Include entrances between columns and consistent side wings. Use realistic stone and glass materials with subtle weathering. Clean topology, medium-high poly, isolated building, no environment.
