Past Preserved, Future Anticipated.

Philadelphia City Hall is a major civic landmark, built over a period of 30 years.The French Second Empire structure is a National Historic Landmark with more than 990,000 SF of interior space built around a 40,000 SF courtyard. The restoration of City Hall brings the building into the 21st Century with a 12-year, multi-phase plan to preserve the building and grounds, accommodate future uses, and permit the incorporation of new technologies. Kelly/Maiello’s work on the project included development of a Master Plan, a series of interior renovations for a variety of city agencies, and the phased restoration of its historic exterior including masonry, roofing, gutters, flashing, cast iron cornices, windows and sculpture.
