Milstein Hall, OMA's extension of the College of Architecture, Art and Planning (AAP) at Cornell, has been awarded LEED Gold Certification. The award recognizes the design, construction and operation of high performance green buildings in the United States.

OMA's recently completed New Court headquarters for Rothschild bank in London and the new Maggie's Centre in Gartnavel, Scotland, have each received a 2012 RIBA Award for excellence. Both buildings are now contenders for this year's RIBA Stirling Prize. New Court has also won RIBA's London Building of the Year.
