Observing the Comcast Technology Center After the Topping Out of the Concrete Core

7:00 am on July 19, 2021 By Thomas Koloski

The majority of Philadelphia’s tallest skyscrapers stand in Center City to the west of City Hall, which include the Comcast Technology Center at 1800 Arch Street. The supertall, which is the tallest building in the city, has risen into the skyline between 2014 and 2017. Designed by Foster + Partners, the tower’s structure is compromised of a central concrete core surrounded with a steel frame, with the facade mostly clad in glass and metal. The tower was developed by Liberty Property Trust, which collaborated with Comcast to erect their second tower in the city. In this article, Philadelphia YIMBY takes a look back to when the Comcast Technology Center was under construction at the time when the core had just topped out.

Philadelphia features numerous old structures with interesting styles of architecture. One of the city’s oldest tall structures is the Sparks Shot Tower, which started construction in 1807 and was completed on July 4, 1808 at 129-131 Carpenter Street in the neighborhood now known as Queen Village in South Philadelphia. The facility, which predates the Civil War by almost 60 years, was designed by Thomas Sparks and John Bishop, who originated the idea for shot towers. The 143-foot-tall structure, which forms a brick-clad cylinder that tapers to the top, still stands to this day.

Philadelphia YIMBY Presents Massing Renderings of the 1905 Skyline

In the early 1900s, construction has just finished at Philadelphia City Hall (completed in 1901), with the clock tower dominating Center City. The skyline was not yet filled with massive towers. Instead, low- and mid-rise buildings made up the urban landscape. At the time, the city was growing rapidly, and a new generation of notable buildings was completed by the turn of the 20th century, including City Hall and the Masonic Temple. Today Philly YIMBY presents massing renderings of the Philadelphia skyline as it appeared all the way back in 1905.

A Look at Commerce Square, Philadelphia’s Twin Towers

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.

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.

Philadelphia YIMBY Compares Massing Renderings of the 1945 and the 2020 Skyline

7:00 am on May 29, 2021 By Thomas Koloski

In the mid-1940s, the Philadelphia skyline still maintained the general look it received during the construction boom of the 1920s and 1930, when several new towers added significant mass to the Center City skyline. The Philadelphia City Hall still topped the skyline at 548 feet tall, but by the 40s more high-rises were nearing the top of the clock tower, with several rising in the 300-foot range. A number of Art Deco buildings stood out, with predominantly light and dark brown shades. Today Philly YIMBY compares massing renderings of the 1945 skyline and the 2020 skyline.

A Look At The Lewis Tower At 1425 Locust Street in Rittenhouse Square, Center City

Philadelphia is home to a sizable collection of intricately designed skyscrapers that were built between 1920 and 1940, which still stand out on the cityscape despite being drastically shorter than the modern towers of Center City. The east side of the Rittenhouse Square neighborhood features many towers built within that time frame, including The Lewis Tower, now known as The Aria Condos at 1425 Locust Street. The structure rises 389 feet and 33 stories tall, just one block to the north of the 375-foot-tall tower known as The Drake. The skyscraper was designed by Edmund Gilchrist, and Gravell and Hall engineered the steel structure. The Art Deco building was completed in 1929.

During the 1920s, “the Roaring Twenties,” the nation saw a major economic boom that lasted nearly a decade, until it came crashing down in the 1930s with the Great Depression. Major cities were vibrant and illuminated, with ballrooms and theaters spreading around cities. The growth also positively affected the skylines of American cities, including that of Philadelphia, which saw the construction of multiple office buildings in Center City, mostly around Broad Street and Market Street.

With the growth of rail transit in the early 1900s across the country, Philadelphia’s train network was also expanding. After the construction of the Broad Street Station, the larger 30th Street Station was built in University City, West Philadelphia, in order to increase the capacity of local transit. Built by the Pennsylvania Railroad, the station sits on the west side of the Schuylkill River, right in the middle of where John F. Kennedy Boulevard would run, with rail lines running and under the station and across the river. The Classic Revival structure was designed by Graham, Anderson, Probst & White, which also designed the Suburban Station in Center City and The Wrigley Building in Chicago.
