“The leader of an artists’ cooperative has been sentenced to probation for setting up a secret apartment inside a shopping mall’s parking garage as part of a project on mall life. Michael Townsend, 36, said he and seven other artists built the 750-square-foot apartment beginning in 2003 and lived there for up to three weeks at a time. The artists built a cinderblock wall and nondescript utility door to keep the loft hidden from the outside world.”
