A conceptual proposal for the retrofit of an old grain silo in Center City Philadelphia, Interface Studio Architects aims to integrate an existing, vacant structure into an urban, mixed-use project. Additionally, it raises interesting questions about old building reuse and innovative tactics for sustainability. More images and architects’ description after the break.
The Granary’s specific and robust silo structure makes the conversion to residential or commercial space impossible for at least half the building. However, an engineering analysis revealed that the existing structure can accept a significant overbuild with only minor reinforcements. Our proposal occupies the first floor with retail and restaurant uses while adding dozens of apartment over top across 14 floors.
