This architectural drawing is a Staircase plan and section design with details in AutoCAD 2D drawing, CAD file, and dwg file. The basic function of stairs is to give a straightforward and easy way of traveling between floors. Houses and shelters had only one story in ancient times, but it was discovered that the area above ground level could be used to expand the amount of space a construction could offer.
