This past February, the Smithsonian chose six architectural firms to create concepts for the $500 million museum, which will be built on 5 acres between the National Museum of American History and the Washington Monument. With apologies to the Smithsonian, I've messed up its map with a blue circle (left), so you can see where the new museum will be built.
The six models proposed to the Smithsonian are on display at the Castle Building, at the Information Center on the Mall. Both 3-dimensional models and drawings are included for observation.
1. Devrouax + Purnell Architects & Pei Cobb Freed & Partners Architects
2. Diller Scofidio + Renfro In Association With Kling Stubbins
