The Olive Exchange Prominent high-rise structures in Philadelphia such as the Academy of Natural Sciences and the Franklin Institute Museum were designed by Philadelphia Architect John Torrey Windrim. Windrim was known for the classic revival-style architecture, more commonly known as the Beaux-Arts period where he introduced style into the public sector. The Exchange was originally constructed in 1902. When we first started this project, we found the building had been vacant and abandoned for over 30 years. Walls and ceilings had crumbled and fallen under their own weight, while the debris-laden elevator cab was hanging trapped between floors. Despite the obvious signs of degeneration, the original reinforced concrete floors and massive exterior brick walls remained robust and secure. The detailed exterior brick and grand ornamental metal stair tower is reminiscent of the Exchange’s old world charm. In the coming year, the Exchange’s interior will be transformed into attractive yet moderately priced loft-style living spaces. Natural daylight will flood through the Exchange’s massive windows. Views from the Exchange’s upper floors and roof deck offer spectacular panoramic views of the Philadelphia skyline. Bi-level penthouse on the top floor will offer Torrey’s original industrial-sized skylights and 18’-0” ceilings throughout.
