A couple of weeks ago, some of the Architectural Record staff (and maybe some of you) attended the Architectural League of New York's Beaux Arts Ball, its annual fête. This year's ball was held in the cavernous drill hall of 69th Regiment Armory in Manhattan (home of the 1913 Armory Show).

Brooklyn-based Situ Studio designed the installation—suspended, lightweight structures made of fire-retardant polyethylene sheets and off-the-shelf aluminum electrical conduit. Check out the time-lapse video above, which shows the environment being installed in the drill hall, and the ensuing party, complete with lighting design by Renfro Design Group and dancing, figurative puppets by Processional Arts Workshop.
