building facade 3d model

Generate a 3D model of this building facade based on the provided image. Use real-world metric scale. Reference dimensions: - Left window size: 2.30 meters wide x 2.05 meters high. - Vertical repetition from window base to window base above: 2.45 meters. - Horizontal structural band between windows: 0.40 meters high. First, reconstruct the building facade faithfully using these proportions. Then apply a full retrofit modernization: - Replace all existing windows with white PVC window systems (70 mm profile). - Visible frame width: 60 mm. - Double glazing thickness: 24 mm. - Standardize all window alignments vertically and horizontally. - Improve facade uniformity while maintaining the original structure. - Keep balcony positions and structural slabs unchanged. Do not redesign the building. Do not change floor count. Maintain structural geometry. Create clean architectural geometry suitable for SketchUp refinement. Export in OBJ or GLB format using meters as unit scale.
