The Freelon Group showed off renderings for their renovation of Mies van der Rohe’s Martin Luther King Jr. Memorial Library in downtown Washington, D.C. Presented to the library’s Board of Directors as part of a long-running discussion over what to do with the central library, the scheme includes a four-story atrium, two additional floors for new tenants, a landscaped public roof garden, and a new ground-level café. According to developer Jair Lynch, the project would cost $175 to $200 million.
