Out of a crop of 26, ten teams have been invited to present their technical proposals for the renovation of the Mies van der Rohe–designed Martin Luther King Jr. Memorial Library in Washington, D.C. District officials are hoping to transform the landmark 1972 building, Mies’ last built work and his only in D.C., into a state-of-the-art central library fit for the nation’s capital. The finalists are Cunningham Quil Architects and 1100 Architects, Ennead Architects and Marshall Moya Architects, Leo A. Daly and Richard Bauer, Martinez and Johnson Architects and Mecanoo Architects, OMA and Quinn Evans Architects, Patkua Architects and Ayer Saint Gross, REX and Davis Carter Scott Architects, Shalom Baranes and Davis Brody Bond, Skidmorw Owings & Merill, and Studios Architecture and The Freelon Group. With the library’s plumbing, HVAC and elevator systems in need of replacement, asbestos present throughout the building, and annual maintenance costs soaring to $5 million, the aging athenaeum demands some serious work. Library officials have given their chosen architects a few different options, from a simple update of the building’s ailing systems, to construction of two additional floors or a complete gutting the interior. Either way, the transformation is scheduled to wrap up by 2018.
