Residential Stair Design Drawing With Riser Tread Width Details

This stair design drawing is prepared in AutoCAD format and presents a clear and practical stair layout suitable for residential building projects. 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 standard stair width around 900 mm, along with landing connections and step alignment for smooth vertical circulation. This stair design detail helps architects and civil engineers plan functional staircases that comply with common building standards and spatial requirements.

The AutoCAD stair design drawing includes accurate dimensions, clean annotations, and consistent line work for easy coordination with floor levels and structural elements. This stair drawing is useful for interiordesigners and builders who require reliable stair sections and plan information during execution.
