REX is an internationally acclaimed architecture and design firm based in New York City, whose name signifies a re-appraisal (RE) of architecture (X). Led by Joshua Prince-Ramus, REX operates across many scales, consistently challenging and advancing building typologies, and promoting the agency of architecture. The subject of numerous international exhibitions and publications, the work of REX has been recognized with many of the profession's top accolades, including the American Institute of Architects' National Honor Award in 2005 and 2010.

While REX was still known as OMA New York, Joshua was Partner in Charge of the Guggenheim-Hermitage Museum in Las Vegas and the Seattle Central Library, hailed as Time magazine's 2004 Building of the Year and by Herbert Muschamp in the New York Times as "the most exciting new building it has been my honor to review in more than 30 years of writing about architecture." In 2005, the Seattle Central Library was awarded the top honors bestowed by the American Institute of Architects, the American Council of Engineering Companies, and the American Library Association.

Among REX's recently completed work, the Wyly Theatre received the American Institute of Architects' 2010 National Honor Award, the American Council of Engineering Companies' 2010 National Gold Award, and the U.S. Institute for Theatre Technology's 2012 National Honor Award. The Vakko Fashion Center was presented ArchDaily's 2010 Office Building of the Year, Wallpaper* magazine's Design Award 2011 for Best Workspace, and ICON magazine's Award 2011 for the World’s Coolest Office.
