Katherine North is the principal and founder of Northbrook Design, which specializes in designing interiors for residential and hospitality projects in the San Francisco Bay Area and New York. North entered into interior design in part because she loves reading interior-design magazines, and someone once told her that a good career is one in which you’re happy to read the trade magazines. Her greatest design anxiety is having a sofa not fit through the doorway, and her least favorite decorative object is a torchiere floor lamp. “No one should be allowed to fabricate, sell, or purchase them, but every bachelor in America seems to have one.”
