Interior Work Continues at the Riverwalk North Tower in Center City West

8:00 am on June 1, 2021 By Thomas Koloski

Though the first portion of the Riverwalk North tower at 60 North 23rd Street opened back in March, work continues at the residential interiors, which will soon wrap construction. Designed by Gensler, the Riverwalk project consists of two towers standing atop four-story podiums holding retail space. The north tower is the shorter of the two, at a height of 315 feet and 28 stories. The south tower stands 362 feet tall with 32 stories. The project is developed by PMC Property Group, which is also behind other in-progress projects that are helping transform Center City West into a development hub. Notably, Gensler’s founder, Art Gensler, has recently passed away on May 10th, just two days after the passing of Helmut Jahn, another architect notable for his contributions to Philadelphia and beyond.

Since Arthaus at 311 South Broad Street in Center City topped its concrete structure, the pinnacle of the building has seen much construction activity as steel at the parapet continues to rise, nearing its final height of 542 feet. The 47-story tower is designed by Kohn Pedersen Fox, a firm behind well-known structures such as 30 Hudson Yards and One Vanderbilt in New York City, and the Mellon Bank Center at 1735 Market Street. The developer, Dranoff Properties, owns many properties around the city, such as Symphony House and a future residential building at 337 South Broad Street.

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.

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

7:00 am on May 21, 2021 By Thomas Koloski

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.
