OPEN AIR SHOPPING CENTRE Generally, open malls are single-floor shopping malls and there is ample parking space available in front of each shop. Sidewalks connect the various zones of the open mall. Typically, open malls may range from 5,000 to 10,000 sq. Unlike enclosed malls, an open-air shopping center includes rows of stores spread over an area with a sidewalk or pavement in front. Think of it as an organized “high street” with the comfort of a mall.
