Ever since the Cira Centre tower emerged from the ground next to 30th Street Station two years ago, the developer, Jerry Sweeney, has been looking to clone that visually thrilling office building. His chance came this summer, when he made a $28 million deal with the University of Pennsylvania for a two-block parcel south of the train station.
Penn offered Sweeney the site on the condition that he use its development to conjure a lively, walkable neighborhood from the wasted western edge of the Schuylkill. Announcing the plan for Cira Centre South, Penn president Amy Gutmann predicted Sweeney's lineup of diamond-cut buildings would help suture the historic divide between downtown and West Philadelphia, laying the foundation for the "24/7 neighborhood" that area's two big universities have long craved.
