The American architect Brad Cloepfil founded Allied Works Architecture in 1994. It now employs 40 architects and has offices in Portland, Oregon, and New York City. Allied Works has attracted attention above all for its designs of museum buildings: the Contemporary Art Museum in Saint Louis (2003), the extension to the Seattle Art Museum (2007), the Museum of Arts and Design, New York (2008), and the Clyfford Still Museum, Denver, Colorado, which is still in the planning stages. This book offers a comprehensive survey of the office's projects. A series of conversations with artists and scholars provides insight into Cloepfil's ideas and principles, which form the basis of his work as an architect.
