Rich's Cobb County was enlarged in 1968. The store would be in operation for over 40 years. It was demoted to a Clearance Center before being shuttered in early 2004.

Meanwhile, by 1970, the official name of the shopping hub had morphed to simply COBB CENTER. The complex was soon to loose its exclusive status as only shopping mall in Cobb County.

In 1973, the new shopping center on the block was CUMBERLAND MALL. This superregional complex, which extended for a whopping 1,135,000 square feet, dwarfed COBB CENTER. Cobb County's first mall did a quick "keeping up with CUMBERLAND" renovation, whereby it was renamed COBB CENTER MALL.

As part of the early '70s makeover, open shopping concourses at COBB CENTER MALL were roofed-in and climate-controlled. The remodeling was completed in November 1973. In this circa-'74 site plan, the Rich's expansion of 1968, and an enlargement of the Colonial Stores market, are indicated in gray. The shopping hub now covered approximately 409,600 leasable square feet.
