This may help explain the extra floors that were added to this project. The University of Pennsylvania Health Systems has taken another 55,900 square feet in the building for Penn Presbyterian Hospital. The total space they will now occupy is 211,600 sqft in the building. Good Shepherd Penn Partners is occupying another 28,800 and space will be reserved for Wexford Science and Technology and for the University City Science Center for Tech Incubator space. There will also be 5,500 sq ft of retail space. The building is now 72% pre-leased.

The render in the link is actually for the new apartment building at 3601 Market, NOT this tower.
