Downtown Miami’s Flagler Station building—now home to a Zapatero shoe repair shop, a watch repairer and a Cuban eatery among other mom-and-pop stands—would be a technology hub with offices for startups and app makers from South Korea to Panama.

The boarded up, nondescript building next door to the west once was a Foot Locker and would reopen as a bustling food hall, international spice market and a food development research lab.
