Detailed Stair Section Plan with Side Elevation Design layout

This AutoCAD drawing presents a detailed stair section plan with side elevation design and full dimension references. The stair detail drawing includes longitudinal section, cross section, and plan layout with clearly marked tread depth, riser height, landing length, and slope alignment. Structural support members, beam connections, and base slab interface are illustrated with accurate measurement annotations. Side elevation views define railing height, guard positioning, and vertical level differences. Dimensioned plan design ensures precise construction coordination, safe circulation planning, and structural stability for residential or commercial building execution.
