Interior Stair Detail Design Drawing With Riser Tread Dimensions

This stair detail design drawing is created in AutoCAD format and presents a clear layout of an interior stair configuration suitable for residential and mixed-use buildings. The drawing illustrates stair geometry with defined riser heights generally ranging from 150 mm to 180 mm and tread depths between 250 mm and 300 mm to ensure safe and comfortable movement. It also shows stair width standards around 900 mm along with landing connections and directional changes where straight and angled stair segments are combined. This stair detail drawing helps architects and civil engineers plan efficient vertical circulation while maintaining compliance with common building standards.

The AutoCAD stair detail design includes accurate dimensions, clean annotations, and well-structured line work that supports coordination with floor levels and structural elements. This stair drawing is useful for interior designers and builders who require reliable stair sections and plan information during execution. The stair detail design reduces drafting effort, improves on-site clarity, and supports consistent implementation across projects, making it a practical reference file for professional architectural and construction documentation.
