Architecture critic Inga Saffron writes about the renovation of the University of Pennsylvania building designed by Louis Kahn. She writes that while architecture critics praised the 1960s building, the scientists that it was designed for were not as thrilled with it. The university's architect David Hollenberg, AIA, and his office, working with several firms, have completed the first phase of a renovation of the Richards Medical Research Laboratory: a $13.4-million update of two of the towers. Saffron writes: "The renovation has pared Kahn's spaces down to their essence, restoring a Zenlike calm, and revealing the muscular concrete structure that made the design such a revelation in the early 1960s, when International Style glass towers were all the rage."
