Stair Detail DWG with Step, Tread, Riser, Landing, and Handrail Layout

This stair detail drawing provides a complete architectural and construction level layout designed for residential and commercial buildings. The AutoCAD DWG file clearly illustrates step geometry with standard tread width of 270 mm and riser height of 150 mm to ensure safe and comfortable movement. The total stair width is approximately 1000 mm, suitable for regular building circulation. Landing dimensions are detailed with a minimum depth of 1000 mm to allow smooth transition between stair flights. All nosing edges, step counts, and slope directions are properly marked for accurate execution on site.

The drawing also includes a well defined handrail layout with a handrail height of 900 mm measured from the finished floor level, ensuring compliance with common safety standards. Baluster spacing, handrail fixing points, and support alignment are shown for precise installation. Section and elevation views help users understand vertical relationships, floor to floor height, and landing levels. This stair detail drawing is highly useful for architects, civil engineers, builders, and interior designers who require ready to use reference drawings for working drawings and execution. The AutoCAD DWG file supports efficient design coordination and helps reduce on site errors through clear measurements and professional detailing.
