The 2009 Venice Biennale opened this week with an unexpected and quite beautiful piece of performance art. Artist Mike Bouchet had built a one-to-one scale replica of a typical American suburban home that he planned to install on floating pontoons in the Venice Arsenale basin. He called the project Watershed. 1 of the pontoons capsized, and the entire house sank to the bottom of the canal—an unintentional yet utterly perfect coda to the house’s own built-in commentary. Now, a fake generic American suburban home will add its ruins to the underwater archaeology of Venice.
