Are any readers out there looking to start a design business? Lauren Stern, whose Carroll Gardens apartment was featured on Brownstoner’s The Insider last year, will be teaching a class on the business aspects of striking out on your own. Known for her “cozy, comfortable and warm” style, Stern worked as an interior designer at the firm Wilson Associates and as an event producer for Black Book Magazine before opening Lauren Stern Design in 2007. In addition to working on client projects, she is currently renovating her own house in Boerum Hill. “The Nuts and Bolts of Starting an Interior Design Business” will cover how to charge, the five phases of any interior project, and growing your business, as well as regulatory and legal requirements. The class, which costs $11, will take place at the Brooklyn Brainery at 515 Court Street in Carroll Gardens from 8:30 pm to 10 pm on Dec. 10.
