Called the United States' first modern skyscraper, and one of the most important skyscrapers built in the country in the first half of the 20th century, the building featured an innovative and effective design of a T-shaped tower that allowed the maximum amount of natural light and rentable space. The tower sat on a base with a polished marble facade. The first floor of the base contained space for retail, while the second floor featured the banking hall, bank offices and associated facilities. The Philadelphia Saving Fund Society's offices and banking hall featured custom-designed furniture, including custom Cartier clocks on every floor. The top of the skyscraper featured the bank's boardroom and other facilities for the board of directors. Office tenants were attracted to the tower by modern facilities such as radio receivers, and the building was also the second high-rise in the U.S. to be equipped with air conditioning. The skyscraper is topped by a red neon sign with the Philadelphia Saving Fund Society's initials (PSFS) on it. Visible for , the sign has become a Philadelphia icon. Next to the sign is a television tower erected in 1948.
