There was a moment in the late 1960s when architects (almost always working in groups) wanted to literally lift their projects off the ground and allow them to float over the everyday landscape. Groups like Haus-Rucker-Co, the French Utopie group, and Ant Farm were all inspired by earlier experiments of Archigram, Cedric Price, Buckminster Fuller, and engineers like Frei Otto.

Though these experiments were almost always created for gallery exhibitions or one-off installations (Ant Farm placed a large inflatable bubble at UC Berkeley to warn students about the dangers of pollution in 1970) these works continue to inspire architects and every decade they seem to get rediscovered by a new generation. A current exhibition The New Inflatable Moment at the Boston Society of Architects (BSA) is bringing the work back yet again and even cites a previous show, the 1998 exhibition and book The Inflatable Moment: Pneumatics and Protest in ’68 by Marc Dessauce and The Architectural League of New York, for inspiration and precedent. The French historian of modernism Caroline Maniaque also wrote about inflatables in 2004 for a different generation.

The BSA exhibition also highlights recent projects by Diller Scofidio + Renfro, Grimshaw, Anish Kapoor/Arata Isozaki, the late Otto Piene, and Norman Foster. But the exhibit also includes even newer projects by Graham Stevens, Chico MacMurtrie, and Berlin’s raumlabor. The idea of these projects also includes an element of idealistic utopianism and there is nothing wrong, at the moment, with idealism in architecture.

The show still has a few weeks to run (through September 30th) so if you’re in Boston visit the BSA Space (290 Congress Street, Boston, MA, 02210). Admission is free. Opening hours: 10:00 am to 6:00 pm on weekdays, and 10:00 am to 5:00 pm on weekends and holidays.
