The home's front door opens to the loggia, a feature borrowed from historic Charleston single houses. "The area works as an entry vestibule into the house," says architect Stan Dixon. Thanks to the outdoor space and the central great room, the structure lives large without giving up private spaces. "It's a 3,000-square-foot house, but you can still go to your separate place," says architect Anne McGuire. Her colleague Clay Shackelford explains that the location of the bedrooms offers solitude and privacy. "The guesthouse is at one end and the master bedroom is at the other," he says. "You have a feeling of separation at the end of the day." Adds John, "It's a great idea, especially if you have grandchildren."
