Top 10 Office Projects Under Construction in Philadelphia

Groundbreaking work has been completed for two projects so far in 2020, while one-third of the pipeline is slated for delivery by year-end, Yardi Matrix data shows.

Philadelphia’s growing life sciences sector, robust talent pipeline and central East Coast location have solidified its reputation as a leading market for innovation and technology. The life sciences sector has thrived despite the ongoing pandemic, making way for a steady wave of new development. According to Yardi Matrix data, groundbreaking work has been completed for two projects so far this year. One of these properties—One uCity Square—is on the list below.

The metro’s office pipeline totaled 2.6 million square feet as of July. A third of these projects is expected to come online by year-end, with the rest scheduled for delivery in 2021. The suburban Conshohocken submarket led construction activity with nearly 690,000 square feet under development. The table below highlights the largest properties underway. The list was compiled using Yardi Matrix data.
