The Rohm and Haas Corporate Headquarters in Philadelphia, Pennsylvania, is the headquarters for the chemical manufacturing company Rohm and Haas. Completed in 1964, the building was the first private investment for the urban renewal of the Independence Mall area. Only two blocks from Independence Hall, the building, designed by Pietro Belluschi and George M. Ewing Co., was lauded for its respect to the nearby park and historical buildings. Philadelphia's city planners praised the building as a standard for all redevelopment buildings. The nine-story edifice's most notable feature is its facade of translucent, corrugated sunscreens; held in place by aluminum lattices, the sunscreens are made of Rohm and Haas's principal product, Plexiglas. In 2007 the building was listed on the National Register of Historic Places and is today considered one of the best examples of the International style.
