Office Building Design 28m x 45m G plus 5 Floor Plans DWG File

This Office building design drawing presents a complete 28m x 45m G plus 5 floor commercial development prepared in AutoCAD format. The file includes the ground floor layout with the entrance lobby, reception area, staircase core, lift shaft, service duct, and open office workspace planning. Typical upper floor plans illustrate flexible office modules, conference rooms, cabins, workstations, meeting areas, and circulation corridors. Structural column grid, beam layout, slab thickness, and wall dimensions are clearly defined to ensure construction accuracy. Curved façade planning and central vertical circulation core are precisely coordinated within the structural framework.
