Some people use balloons to shift their locations, like in the movie Up!, and some use it as a makeshift auditorium. At least that’s what the Hirshhorn Museum and Sculpture Garden has in mind. As a huge addition to its property, they plan to alter their landmark cylindrical building two times each year, thanks to a giant inflatable balloon! Designed by New York-based designing firm Diller Scofidio & Renfro, this structure will provide temporary venues for arts performances, film screenings, and conferences. With a construction cost of $5 million, the balloon will come up during the busy months of May and October every year.
