The dumbell plan property opened in two stages. Jordan Marsh, The Outlet Company and mall proper were dedicated in July 1970. Filene's welcomed first shoppers in September 1970. At this time, the mall encompassed approximately 768,000 leasable square feet, housed fifty stores, and provided free parking for 6,000 autos.

A newly-built J.C. Penney opened at WARWICK MALL in March 1980. The store was added in front of the center's West Entrance.

An early '80s layout includes the aforementioned J.C. Penney. The mall's Outlet Company anchor store had been shuttered in August 1982. It was replaced by a Caldor discount mart in March 1983. With these modifications, WARWICK MALL encompassed around 912,000 leasable square feet.
