One Logan Square is an American high-rise building that is located in the Logan Square neighborhood of Philadelphia, Pennsylvania. The building stands at 400 ft (122 m) with thirty-one floors, and was completed in 1983. The architectural firm responsible for the building's design is Kohn Pedersen Fox Associates PC.
It is currently the 31st-tallest building in Philadelphia.
This building and accompanying Four Seasons Hotel (now The Logan Hotel) were developed by a joint venture of INA and Urban Investment and Development Co. for $120 million.[2] As the zoning laws at the time prohibited buildings taller than 80 feet facing Logan Square, building the low-rise hotel on the square allowed construction of the office building.[3]
The law firm Morgan, Lewis & Bockius was one of the anchor tenants at the property at construction and received an equity stake as part of its lease agreement.[4]
The Rubenstein Company acquired the building along with Two Logan Square in 1997 from Aetna for $55 million.[5][6] Brandywine Realty Trust acquired the property as part of its acquisition of Rubenstein's portfolio in 2014.[7]
It is currently the 31st-tallest building in Philadelphia.
