From the Publisher. From 2008 to 2010, Madrid-based architects Mansilla + Tuñón taught at the Princeton University School of Architecture. Luis M. Mansilla + Emilio Tuñón – From Rules to Constraints brings together the essential ideas of the studios held by the architects. The book focuses on the atmosphere of the studios through the lens of each discussed site: the Farnsworth House in Plano, Illinois, the Spanish Royal Collection Museum, and the Gran Via, both in Madrid, Spain. In addition, the book includes a series of photo essays by photographers Dean Kaufman, Luis Asin, and Luis Baylón, and texts by Stan Allen, Enrique Walker, Sarah Whiting, and Agustin Perez Rubio.
