The New Museum today announced that it has selected OMA to design its expansion. This will be the first public building in New York City designed by Rotterdam-based Rem Koolhaas and Shohei Shigematsu, director of the firm’s New York office.

Since plans for an expansion were revealed last May, speculation within the New York architecture scene mounted about who would design it. The short list included OMA, SO-IL, Selldorf Architects, wHY, and SANAA, the Tokyo-based firm that designed the museum’s first freestanding building in 2007. That building, with its seemingly precariously stacked galleries, became an instant icon and was transformative for its Lower East Side neighborhood, which has since welcomed a number of prestigious galleries and hotspots, including Foster + Partners’ Sperone Westwater Gallery, and, most recently, the towering Public Hotel by Herzog & de Meuron.
