In 2003, a group of eight artists covertly built a living space in an unused part of the parking structure for Providence, Rhode Island’s gargantuan Providence Place shopping mall. Upon the apartment’s discovery in 2007, it became a brief local news sensation, before the story was largely forgotten. Jeremy Workman has brought the group back together to tell the tale in his documentary Secret Mall Apartment. We sat down with Workman for a call to discuss the unusual art project, the footage his subjects captured, and how he gained their trust to make the documentary after they’d denied other filmmakers for years.
