Earlier today, we told you about plans to create a whimsical temporary event space in the form of a massive bubble through and around the donut hole-like center of the Hirshhorn Museum and Sculpture Garden. Since then, we’ve managed to obtain some more images of the proposed design, which has been conceived by New York architecture firm Diller Scofidio + Renfro.

The firm has been involved in the design of several high profile cultural institutions, including the Institute of Contemporary Art in Boston and the redevelopment of Lincoln Center, and was one of the firms that bid on the future National Museum of African American History and Culture (it was not the winner). Most recently, though, Diller Scofidio + Renfro won accolades for its design of Manhattan’s The High Line. All images above are courtesy Diller Scofidio + Renfro.
