History and architectural features

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.{{cite news |url=https://www.newspapers.com/image/171837086 |title=Kelly Wolfington |work=Philadelphia Inquirer |date=1981-01-05 |accessdate=2021-02-11}} 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.{{cite news |url=https://www.newspapers.com/image/171802525 |title=For City, a World Class Hotel |work=Philadelphia Inquirer |date=1980-11-19 |accessdate=2021-02-11}}
