Looking Back At One Liberty Place Shortly After Completion

7:30 am on January 16, 2022 By Thomas Koloski

Between 1984 and 1987, a new monolith was constructed in the city of Philadelphia. For a long time the skyline was dominated by beige and brown buildings along with City Hall, but the blue-glass One Liberty Place at 1650 Market Street in Center City has broken out of the blocky and old styles and also broke the unofficial 548-foot height limit. Designed by Helmut Jahn of Murphy/Jahn and developed by Willard Rouse of Rouse and Associates, the tower rises 945 feet and stands 61 stories tall. In this feature, Philadelphia YIMBY looks back at One Liberty Place shortly after its completion.

Looking Back to the Moment When One Liberty Place Passed the Statue of William Penn Atop Philadelphia City Hall

7:30 am on January 10, 2022 By Thomas Koloski

For nearly 35 years, the Philadelphia skyline has been dominated by skyscrapers rising well above 500 feet in height. The idea to breach of the height limit informally established by the 548-foot-tall pinnacle of City Hall, also known as the “Gentlemen’s Agreement,” surfaced in 1984. The first tower to rise above the limit was One Liberty Place, a daring structure for the time that rises 945 feet and 61 stories above ground at 1650 Market Street in Center City. The project was designed by Helmut Jahn of Murphy/Jahn and developed by Rouse and Associates (which eventually became Liberty Property Trust), and was completed in 1987. In this feature, Philadelphia YIMBY takes a look back at when One Liberty Place passed the statue of William Penn on top of City Hall.

Looking at the Philadelphia Skyline from the Observatory Atop One Liberty Place

7:30 am on January 5, 2022 By Thomas Koloski

Philadelphia is home to several tall skyscrapers in Center City, with One Liberty Place among the most iconic in the group. The steel-framed tower rises at 1650 Market Street to a height of 945 feet and 61 stories above the ground. The skyscraper was designed by Helmut Jahn, who has unfortunately passed in May of last year, as part of the Liberty Place project developed by Rouse and Associates. At the moment, only two observatories operate in the city, as one has closed last year. Today we look at views from theh currently closed One Liberty Observation Deck, located on the 57th floor in the skyscraper’s gabled crown.

Philadelphia YIMBY Observes Multiple New Lighting Schemes at One Liberty Place in Center City

7:30 am on November 14, 2021 By Thomas Koloski

In recent weeks, new nighttime displays have been lighting up the Philadelphia skyline. The iconic One Liberty Place skyscraper, located at 1650 Market Street in Center City, is the site of one of these new schemes, where new lights now decorate the crown. Developed by Rouse and Associates and designed by Helmut Jahn of Murphy/Jahn, the 61-story tower was completed in 1987 and stands 945 feet tall to the tip of its spire. Today Philadelphia YIMBY observes the most recent displays atop the skyscraper, after The Lighting Practice has finished revamping the decorative lighting.

Philly YIMBY Revisits the Topping-Out of the Spire atop One Liberty Place in Center City

7:00 am on September 28, 2021 By Thomas Koloski

The Liberty Place development in Center City holds a pivotal place in the Philadelphia skyline, having made a gigantic impact on the and the city’s image and its profile as a business hub. A pointed spire tops the tallest tower, the 945-foot-tall One Liberty Place at 1650 Market Street, outfitted with broadcasting equipment. The complex was designed by Helmut Jahn of Murphy/Jahn and developed by Rouse and Associates. In this feature, Philadelphia YIMBY shares images of One Liberty Place from the day the spire had topped out.

Observing the Construction of Two Liberty Place

8:00 am on September 19, 2021 By Thomas Koloski

Among the multiple structures that make up the Liberty Place complex, Two Liberty Place is the second tallest, rising 848 feet and 58 stories, yet it is the largest by area, with 1.2 million square feet. As such, the building is one of the most largest skyscrapers in Philadelphia, as the Comcast Center measures nearly 1.4 million square feet and the Comcast Technology Center holds 1.5 million square feet. Two Liberty Place is located near the heart of Center City at 50 South 16th Street. Just like the rest of Liberty Place, the tower was designed by Helmut Jahn of Murphy/Jahn, who had unfortunately passed away in a bicycle crash in Chicago in May. The project was developed by Willard Rouse of Rouse and Associates, which eventually became Liberty Property Trust.

Looking Back at an Early Iteration of The Liberty Place Complex in Center City

7:30 am on September 18, 2021 By Thomas Koloski

From 1987 to 2007, the tallest building in the Philadelphia skyline was One Liberty Place at 1650 Market Street in Center City, rising 945 feet and 61 stories tall, closely followed by the adjacent Two Liberty Place at 50 South 16th Street, which stands 848 feet and 58 stories tall and was completed in 1990. Designed by Helmut Jahn and developed by Rouse and Associates (later known as Liberty Property Trust), the Liberty Place complex features a fantastic glass, metal, and stone design. Today, Philadelphia YIMBY looks back at an earlier iteration of the complex when the towers were still in designing stages in 1984.

Visualizing the Under-500-Foot-Tall Early Iterations of Liberty Place on the Skyline

8:00 am on September 16, 2021 By Thomas Koloski

The Liberty Place complex is emblematic of the Philadelphia skyline as they played a key role in Center City‘s skyscraper growth. The towers currently stand 61 and 58 stories tall, with angled sharp crowns pointing toward to the sky, one tower capped with a tall and another with a short spire. The project was commissioned by Willard G. Rouse III of Rouse and Associates, who had originally pictured a $150 million 38-story tower rising to a height that measured somewhere under 500 feet. Just days after New Year’s Day in 1984, the building was first discussed in a publication about how Rouse won the bid for the site how it may become the city’s premier office tower. The architect, Helmut Jahn, was selected in March, and had produced a rapid succession of concepts under 500 feet, which eventually evolving well above that height. Today we share exclusive massing concepts of how the skyline would have looked if the towers were built to their originally planned height.

My Liberty Lights Program Is Underway at One Liberty Place

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

Over the course of the past two years, the decorative illumination at the crown of One Liberty Place at 1650 Market Street in Center City has been under renovation, as it is being upgraded with powerful lights that can be animated into various schemes and colors. Designed by Helmut Jahn of Murphy/Jahn and developed by Rouse and Associates (later known as the Liberty Property Trust), the tower was completed in 1987 and stands 945 feet and 61 stories tall. The contractor for the illumination upgrade is The Lighting Practice, which has also decorated the W/Element Hotel. The new lighting system is integrated with the My Liberty Lights program, which allows certain users to change the exterior lights atop the building once per day for a duration of five minutes.

A Look at Early Iterations of Liberty Place When It Was Planned to Rise Under 500 Feet in Height

7:30 am on August 23, 2021 By Thomas Koloski

The Liberty Place complex in Center City is known for being the first building in Philadelphia to dramatically break the unofficial 548-foot height limit that was set by the statue of William Penn on top of City Hall. Upon completion, One and Two Liberty Place were the tallest skyscrapers on the skyline, standing at a height of 945 and 848 feet, respectively. The towers were designed by Helmut Jahn and developed by Rouse and Associates, which eventually became Liberty Property Trust. In this feature, Philadelphia YIMBY takes a look back at a number of early iterations of the complex when the towers were planned to stand around or under 500 feet in height.
