AIA Home Tours Featuring a Church to Condo Conversion

As part of this year’s AIA Home Tours hosted by AIA Philadelphia, 7111 Germantown Avenue offered visitors a rare opportunity to experience how adaptive reuse can preserve a historic community landmark while introducing a new model for residential living in Philadelphia.
