Past preserved, future anticipated.

Philadelphia City Hall is a major civic landmark that was built over a period of 30 years.The French Second Empire structure is a National Historic Landmark with more than 990,000 square feet of interior space built around a 40,000-square-foot courtyard. Its restoration brought 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 sculptures.
