The National Building Museum in Washington, D.C. has opened BIG Maze, a preview of an exhibition on the Denmark– and New York–based Bjarke Ingels Group, a.k.a BIG, which is slated to open in 2015. The maze’s outer most walls are 18 feet high and they decrease in height toward the center of the plan, giving visitors progressively better views of the rest of the labyrinth as they walk further into it. As a result, getting out of the maze is much easier than reaching its center. There is only one entrance and one exit, but there are numerous paths that can be taken to find the other end. BIG Maze is open through September 1.
