Upon its completion in 1972, EASTERN HILLS was the largest shopping mall in -or around- Buffalo. The single-level complex housed over 900,000 leasable square feet. In addition to its major department stores, it housed medium-sized Jenss and Woolworth operations. There were also freestanding Penney's and Sears Auto Centers.

The first major renovation was done in 1986-1987. In this rendering we see the prospective Treats Food Court.

In a circa-1987 site plan, we see that the Hengerer's store is now operating as a Rochester-based Sibley's. The new Treats Food Court is shown in gray. This small addition would be the only physical expansion ever been done to the 900,000 square foot buying behemoth.

The footprint of EASTERN HILLS MALL in 1998 is unchanged from the 1987 layout. There were nameplate modifications, nonetheless. Woolworth's spot has housed a Waccamaw's HomePlace (the store closed in February). Sibley's was now Kaufmann's, AM&A's was The Bon Ton and Jenss has morphed into a Burlington Coat Factory.
