Design plan of the space under the hair salon staircase

Quick answer：

A design plan for the area beneath the staircase in a hair salon would typically include considerations for functionality, aesthetics, and safety. It might involve floor plans showing the layout of the space, elevation drawings to illustrate the vertical design, and 3D renderings to provide a visual representation of the space. The design should accommodate storage for salon equipment, foot traffic flow, and may include lighting, ventilation, and decorative elements. The specifics would depend on the salon's size, client needs, and overall architectural style.
