Liberty Place is a building complex consisting of two skyscrapers, a hotel, parking garage, and a shopping mall that connects the structures. Located in Center City, Philadelphia, Pennsylvania, Liberty Place was designed by Chicago based architectural firm Murphy/Jahn. Architect Helmut Jahn designed One Liberty Place and was a consulting architect for the rest of the complex. The two skyscrapers are constructed with a steel structure held up with eight large pillars on the buildings' perimeters and a central core that contains the elevators. The perimeter pillars are connected to keep the towers rigid while allowing for the maximum amount of interior space. The exterior of the towers are made up of granite, aluminium, and glass panels, with the amount of glass used increasing at the towers' spires. The majority of the exteriors on the lower levels and rest of the complex is made of stone.
One Liberty Place
Located on the corner of Market and 17th Streets, One Liberty Place is 61 stories tall. At 945 feet (288 m), it is the second tallest building in Philadelphia. One Liberty Place contains 1,200,000 square feet (110,000 m2) with an average floor size of 24,000 square feet (2,200 m2). Helmut Jahn is an admirer of American eclecticism and Art Deco and when designing Liberty Place he used New York City's Chrysler Building as a reference. Rouse said that he calls it the "Son of Chrysler" because of the similarity in design. The most notable similarity to the Chrysler Building is the 146 feet (45 m) tall spire that crowns the skyscraper. One Liberty Place's spire is made up of four gabled setbacks leading up to a 2-ton, 47 feet (14 m) long steel spire on top. Instead of curved setbacks like on the Chrysler Building, One Liberty Place's setbacks use straight angular edges.
Like the Chrysler Building, One Liberty Place has a square shape with recessed corners. The facade is also inspired by the Chrysler Building, using glass and aluminum to invoke the Chrysler Building's horizontal and vertical shapes along the building's core. The facade's color ranges between grays, silver, and metallic blues and uses horizontal bands of granite and glass to de-emphasize the visual impact of the height of the tower. The building's lobby features white and gray marble imported from Italy. The elevator lobby and the elevator cabs echo the shape of the building's spire while the elevator doors feature abstraction of One Liberty Place itself
