This is not a condo. Actually, it is—a new development of four floor-through condos rising in Chelsea at 300 West 18th Street. "This Is Not a Condo," though, is one of the catch-phrases gracing the worksite. What this means for new development marketing in Manhattan, we dare not suggest. (We do know, however, that the property will be marketed by Elliman's Rob Gross.) Above and after the jump, more metamarketing fun!
