One Liberty Place

One Liberty Place

Located on the corner of Market and 17th Streets, One Liberty Place, built between 1985 and 1987, is 61 stories tall. At 945 feet (288 m), it is the third-tallest building in Philadelphia. One Liberty Place contains 1,200,000 square feet (110,000 m), with an average floor size of 24,000 square feet (2,200 m). Helmut Jahn is an admirer of American eclecticism and Art Deco; 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-foot-tall (45 m) spire that crowns the skyscraper. One Liberty Place's spire is made up of four gabledsetbacks leading up to a 2-ton, 47-foot-long (14 m) steel spire on top. Instead of curved setbacks like on the Chrysler Building, One Liberty Place's setbacks use straight angular edges.
