Designer and host of HGTV's Curb Appeal.
San Francisco-based John Gidding graduated with a master's in architecture from Harvard, then appeared in shows like Knock First and Designed to Sell. He also opened his own interior design business in New York in 2005 (and still keeps an office and apartment in the Big Apple). His favourite front door colours are emerald, cerulean and robin's-egg blue: "You don't see them that often, but everyone comments on a beautiful front door. Fire-engine red has been done to death," he says. When it comes to sprucing up your façade, Gidding offers some valuable advice: "You can change your mailbox, lighting, house number and paint the front door, typically for under $200, to achieve a new look. Make sure all the finishes match. These are the first things people look for when they come to your house."
