Flat Section Drawing with Staircase and Structural Detail Views

This AutoCAD DWG file provides a detailed flat section drawing with staircase and structural detail views. The drawing includes two different section types illustrating internal floor levels, slab thickness, wall alignment, and vertical circulation layout. The staircase section drawing clearly represents tread and riser arrangement, landing positions, and connection with floor slabs. Structural components such as beams, columns, foundation base, and floor-to-floor height references are shown with dimensional accuracy to support construction planning. The building section plan also highlights facade alignment and internal room configuration within the residential structure.
