One Liberty Place Lighting Nearly Complete with Upcoming Event in Center City

8:00 am on August 11, 2021 By Thomas Koloski

Over the course of the past few months, an upgrade of the decorative lighting system has been in progress at One Liberty Place at 1650 Market Street in Center City, where the light strips that highlight the angled top of the tower are being reworked. Designed by Helmut Jahn of Murphy/Jahn and developed by Rouse and Associates, the two massive skyscrapers of Liberty Place were the first in the Philadelphia skyline to boldly break past the informal 548-foot height limit established by the tower of City Hall nearly a century earlier.

Comparing The 2014 and Final Design of The Comcast Technology Center

Soon after the completion of the 973-foot-tall Comcast Center in 2008, which stood as the tallest building in Philadelphia, local residents and outside watchers wondered what was next for the city skyline. Almost six years later, on January 15, 2014, the design for the Comcast Technology Center, then known as the Comcast Innovation and Technology Center, was revealed to the public. The tower would become the new tallest skyscraper in Philadelphia, planned to stand 1,121 feet tall at 1800 Arch Street in Center City, across the street from the previous record-holder. The design by Foster and Partners was an unfinished version of the current building, as many portions of the building had to be finalized. The developer of the Comcast Technology Center is Liberty Property Trust, which met its fate when it was purchased by Prologis Inc. In this YIMBY feature, we compare the 2014 design and the current version of the skyscraper using renderings, architectural models, and photographs.

Construction is nearly complete at the W/Element Hotel, a 617-foot-tall, 52-story skyscraper that stands at 1439 Chestnut Street (alternately 1441 Chestnut Street) in Center City. Designed by Cope-Linder Architects and developed by Chestlen Development, the dual-branded tower holds a total of 755 hotel rooms. Tutor Perini is the general contractor, and The Lighting Practice is responsible for the vertical strips of that light up at night.

Looking Back At Developments Under Construction In 2017

7:30 am on August 8, 2021 By Thomas Koloski

Philadelphia has had certain key years when skyscraper construction saw a notable surge, when many developments were underway at the same time. For instance, much of the current Center City skyline took form in and just after 1987. Another key year for construction took place in 2017, when various high-rise projects spanned multiple neighborhoods. Most of these developments stood under 500 feet, with some barely noticeable from afar, yet others added significant bulk to the skyline. The tallest skyscraper under construction was the Comcast Technology Center, the city’s first supertall tower and still the city’s tallest building. In this publication Philadelphia YIMBY looks back to when this collection of developments was underway four years ago.

A Look Back At The Unbuilt Park Tower In Center City

8:00 am on August 6, 2021 By Thomas Koloski

During its boom years in the 1980s and the 1990s, the Philadelphia skyline saw multiple tower proposals, many of which ended up not being built. Among these was Park Tower, located at 1501 Arch Street in Center City. Designed by Skidmore Owings and Merrill, the two-towered development would include a 32-story, 480-foot-tall building on Cherry Street and the shorter high-rise standing 230 feet and 18 stories tall. The buildings would feature facades clad in red brick and white stone cladding. Today Philadelphia YIMBY looks back at the development and how it would fit into the skyline.

YIMBY Presents Massing Renderings of the Fourth Design for the PSFS Building

7:30 am on August 5, 2021 By Thomas Koloski

In the past month, YIMBY has posted multiple publications on the PSFS Building and its history. The building stands at 1200 Market Street in Market East, Center City, with a height of 491 feet that dominates the local skyline even now, and did even more so when it was recently built. The tower was designed by George Howe and William Lescaze, who drew up several designs of the building prior to construction. In this feature, Philadelphia YIMBY shares the fourth iteration of the PSFS Building, which also had a physical model built.

YIMBY Presents Massing Renderings of the Second Design for the PSFS Building

7:30 am on August 3, 2021 By Thomas Koloski

In recent weeks, Philadelphia YIMBY has shared a series of publications on the historic PSFS Building at 1200 Market Street in Market East, Center City. Yesterday we looked in detail at the first iteration of the building designed by architects George Howe and William Lescaze, who partnered in 1929. In this feature, we present massing renderings of the second design. The roof height of the current building stands 491 feet above the ground, which is likely as high as the iterations analyzed here would have also risen.

YIMBY Presents Massing Renderings of the First PSFS Building Design

7:30 am on August 2, 2021 By Thomas Koloski

In the 1920s, banks were looking for space in cities around the country as the economy boomed. In Philadelphia, multiple high-rises were under construction and in proposal stages as Center City was rapidly transforming. One of these financial institutions, the Philadelphia Savings Fund Society, was scouting the city for space for a new office building and eventually selected the site at 1200 Market Street, where the William Penn Charter School once stood. Architects George Howe and William Lescaze designed the PSFS Building, which stood as one of the most massive buildings in the skyline for decades. In this feature, Philadelphia YIMBY presents massing renderings of an early iteration of the that was drawn up in 1928.

YIMBY Presents Massing Animations of The Philadelphia Skyline Growth from 1985 to 1990

8:00 am on July 30, 2021 By Thomas Koloski

In recent months, YIMBY shared multiple publications covering the historical status of the Philadelphia skyline. Though our massing renderings have gone all the way back to when City Hall stood alone in the skyline, the modern skyline largely came into being around 30 years ago, when developers finally dared to pass its 548-foot-high William Penn Statue. Philadelphia YIMBY presents our custom animation of the Philadelphia skyline rising between the years 1985 and 1990, when Center City received some of its most iconic skyscrapers.
