Initially built by Chrysler, used for decades to build Volkswagen Rabbits and later Sony televisions, the 2.8 million-square-foot factory industrial building in Mt. Pleasant is a relic, by virtue of its size, of a bygone era in manufacturing. “You don’t have too many three-million-square-foot users looking around,” says Tim White of the Regional Industrial Development Corporation of Southwestern Pennsylvania (RIDC). “But you do have 200,000 and 300,000-foot users.”
