T shaped turning space
Example Solution: Turning spaces for selected 180-degree turns utilize a T-shaped turning space, with the two arms of the T at least 16 inches (410 mm) long at a width of at least 40 inches (1020 mm), and the leg of the T at least 24 inches (610 mm) long at a width of at least 40 inches (1020 mm).
isUD solutions are based on years of evidenced based research.
Each solution indicates the applicable Goals of Universal Design and building project phases (i.e., Initiate, Schematic Design, Design Development, Specifications, and Operations). Many of the solutions have supporting information including drawings, photographs, and best practices that provide easy references for designers. Design Resources summarize the state of knowledge in specific fields such as anthropometry of wheeled mobility, wayfinding technologies, and many more!
The isUD currently focuses on design of public and commercial buildings and facilities.

Examples include: retail, dining, assembly, office,  educational, museums, civic, lodging and other public accommodations.

isUD recognition can be earned for new construction, additions, renovations, adaptive reuse projects as well.
