The Mayfair Theatre was built as a northwestern outparcel of the shopping complex. Originally a single-screen venue, it opened for business in October 1963 and was the first of two movie houses to operate at the mall.

A 2-level, enclosed area known as The Bazaar was built at the Main Entrance of the (still) open-air MAYFAIR CENTER. This mall-within-a-mall, dedicated in October 1971, was a hip and groovy collection of boutiques catering to those on the younger side of the "Generation Gap."

In January 1973, work got underway on the enclosure of the entire shopping center. The "new," fully-enclosed MAYFAIR MALL was officially dedicated on October 11, 1973.
