The Comcast Technology Center at 1800 Arch Street in Center City was completed on August 12, 2019, when the hotel portion officially opened, becoming the tallest skyscraper in Philadelphia. The tower stands 1,121 feet and 60 stories tall, with a central concrete core and steel floor plates. The skyscraper was designed by Foster and Partners, which has designed several buildings that features metal highlights and bright lighting features, and developed by Liberty Property Trust, which used to be known as Rouse and Associates when Willard G. Rouse III ran the company before his death. Today YIMBY looks at the process of testing the lighting at the building’s lantern around the time of its completion.

A Look at Commerce Square, Philadelphia’s Twin Towers

7:30 am on June 12, 2021 By Thomas Koloski

Philadelphia is home to many skyscrapers designed by well-known architects from around the world. Among these are the twin towers of Commerce Square, which were designed by the renowned firm of I.M. Pei & Partners. The 565-foot-tall One Commerce Square and Two Commerce Square towers are still prominent on the Philadelphia skyline to this day, and they take up an entire city block at 2001 Market Street and 2005 Market Street in Center City. Both of the 41-story structures are framed in steel, and each is topped with a decorative diamond on the east and west faces. Maguire Thomas Partners was the developer of the towers at the time of the completion of One Commerce Square in 1987 and five years when Two Commerce Square was completed, which was also the time when the developers decided to split their partnership.

Looking at Two Liberty Place, Philadelphia’s Fourth-Tallest Building, in Center City

8:00 am on June 8, 2021 By Thomas Koloski

The majority of the skyscrapers that dominate the Philadelphia skyline are the trophy towers that were built in the late 1980s. One of these buildings is the 848-foot-tall, 58-story Two Liberty Place at 50 South 16th Street in Center City, the city’s fourth-tallest building. The skyscraper is a part of the Liberty Place complex that consists of two towers connected by a mall and a hotel. The skyscraper was designed by Helmut Jahn, who also designed buildings such as MesseTurm in Frankfurt, Germany, 50 West Street in New York City, and the Bank of America Tower in Jacksonville, Florida, among many others. The developer of the project was Rouse and Associates, which eventually transformed into Liberty Property Trust, which built both of the Comcast skyscrapers that today dominate the skyline.

The Center City skyline had drastically changed in the late 1980s with the construction of newly approved skyscrapers standing over the former, informal 548-foot height limit established by City Hall. In late 1990, Mellon Bank Center, located at 1735 Market Street in Center City, joined the skyline with its bright materials alongside the other new, amazingly designed skyscrapers. The tower stands 54 stories above the ground with a total height of 824 feet to the tip of the crown and a roof height of 792 feet. The skyscraper was designed by Kohn Pedersen Fox, which is currently constructing Arthaus a few blocks to the south of City Hall. The tower is owned by Silverstein Properties, which also owns the World Trade Center in Lower Manhattan. The building received a name change for a branding initiative, and is now called the BNY Mellon Center.

A Look At Past Designs for the Bell Atlantic Tower in Logan Square, Center City

8:00 am on June 2, 2021 By Thomas Koloski

In the 1980s, new skyscraper proposals surged after the proposed Liberty Place project was poised to break the 548-foot height limit established by the tower of City Hall. Five of the proposals now stand in the skyline, which include the 739-foot-tall Bell Atlantic Tower at 1717 Arch Street in Logan Square, Center City. Designed by Kling Lindquist, the setbacks of the 55-story skyscraper were partially inspired by structures such as the Empire State Building and One Liberty Place, which itself is similar to the Chrysler Building. Brandywine Realty Trust has owned the skyscraper since 2010, and is now officially known as Three Logan Square. Today Philly YIMBY looks at the alternate designs that were once considered for the structure.

Observing The Comcast Technology Center Shortly After Topping Out

7:00 am on May 30, 2021 By Thomas Koloski

Over the past 40 years, Center City has become home to multiple structures over the height of 500 feet. Philadelphia City Hall was the tallest structure in Philadelphia from 1894 to 1986 at 548, then in 1987 the steel structure of One-Liberty-Place eventually passed the statue to soon top out its spire at 945 feet. The same developers of Liberty Place also developed the next tallest skyscraper in the city, the 974-foot Comcast Center from 2007 to 2017. In 2017, across the street to the west, the Comcast Technology Center became the tallest skyscraper in the city since 2017 and its first supertall skyscraper at 1,121 feet. For this development, Comcast had partnered with Liberty Property Trust, which was originally known as Rouse and Associates. The tower was designed by Foster and Partners, which has designed iconic structures such as the Gherkin in London and the Hearst Tower in Midtown Manhattan. Today Philly YIMBY looks back at the period when the iconic tower’s spire topped out.
