“It is all about connections,” says architect Jeanne Gang, founding principal of Studio Gang. She’s referring to the Richard Gilder Center for Science, Education, and Innovation—a $431-million expansion the firm has designed for the American Museum of Natural History (AMNH) on Manhattan’s Upper West Side. With a late 2022 or early 2023 opening just announced, the project aims to improve visitor flow and relieve congestion inside the labyrinthine campus which encompasses four city blocks and 23 contiguous structures built since the late 19th century, including the original wing by Calvert Vaux and J. Wrey Mould (1877) and Polshek Partnership’s Rose Center for Earth and Space (2000).
