Stalactite

Drift Pavilion, designed for the 8th Design Miami, is a structure made out of several hundred inflatable tubes. The stalactite-like ceilings shelter a courtyard lounge area, equipped with tubular seating. The creators of the pavilion, New York-based Snarkitecture, have designed a floating environment that both defines and negates the presence of architecture.
