ErF World is a private artist-studio complex in the Bushwick/East Williamsburg area of Brooklyn, offering individual studio rentals to artists and designers alongside shared resources. Residents get 24/7 access to communal facilities including large-format printing, a screenprint lab, and a photography studio and darkroom, plus common workspaces used for events such as photo shoots and workshops. The studio describes itself as "a community of working creatives who share ideas and skills while building alongside each other." It also maintains a presence on Instagram as ErF.nyc and ErF.world, and has expanded its footprint with additional leased space in Brooklyn.
