Depending on the space available, establish a range of standard kiosk sizes that could range from about 3 feet by 5 feet to 8 feet by 10 feet, and still ensure ADA compliant access.
Look for unusual or innovative forms or locations for these kiosks. For example, consider the French bouquinistes, which are mounted on top of walls at about eye-level. When they are open, the seller’s goods are easy to peruse.
Where new buildings are to be constructed, consider incorporating exterior nooks to accommodate small vendors. Ensure that any doors provide an attractive street presence even when businesses are closed.
