Peterson Rich Office (PRO) is an architecture and design practice recognized for cultural and publicly engaged projects at multiple scales.

Since establishing their firm in 2014, principals Miriam Peterson and Nathan Rich have led a diverse team in realizing projects for leading clients in the cultural, residential, retail, and public sectors.

The firm has developed a significant body of work around adaptive reuse, especially with projects that introduce new elements into structures of historic significance. Through this work, PRO has developed an architectural vocabulary that embraces context, and finds richness in it as a point of departure for creating something new, rather than something to be smoothed over or erased entirely.

May 2026 will see the completion of new 12,000 sf special exhibition spaces for The Metropolitan Museum of Art adjacent to the Great Hall, with the Costume Institute's annual spring exhibition, Costume Art, which PRO are also designing. The project also includes a new entry to the museum, a new ground level public concourse, and a new stair in the Great Hall, representing the first major investment the Metropolitan Museum has made in public spaces in more than 30 years. Other recent projects of note include the MoMA Design Store in Soho, The Shepherd Gallery & Arts Center in Detroit, the Pruzan Art Gallery at Wesleyan University, and artist studios for Nina Chanel Abney and Mickalene Thomas. Through a multi-year partnership with NYCHA, PRO leads inclusive community design initiatives that inform improvements to the nation’s largest public housing system and advance design excellence across renovations in all five boroughs.
