Situated on the top of a 60-story landmark designed by architect Lord Norman Foster, The Four Seasons Hotel Philadelphia soars above the Center City Philadelphia skyline. PDM was hired in 2016 to assist both the construction and design teams with the constructability of the hotel’s 220 bathrooms, as well as provide drywall and carpentry services for the project.  As the project developed, PDM was also hired to design and construct the elaborate mirrored ceiling in the property’s unparalleled Sky Lobby.
