The $5.2 million expansion project will include units made out of 38 modified shipping containers nearly 10 feet high.
"Part of the reason we selected them was to create a speed to market advantage where we are able to deliver these units, modify them onsite, deliver them onsite, fasten them to the foundation and bring in the site mechanicals, electrical, plumbing and then have them ready for business in a shorter period of time," said Adam Weinstein, President and CEO of The Gadsden Company.
Weinstein says 18 businesses are expected to move in including retail, commercial and restaurants.
Some of the businesses include Beaut Burger, Fat Noodle, Westbound and Transit Cycle.
"What we do at the Mercado San Agustin and has become something that we are known for is not only creating a sense of place, but really unifying the different aspects of culture here in Southern Arizona, but moreover creating a real sense of community," he said.
The expansion will add over 100 jobs on the west side and is expected to be completed by December this year.
