Always jam-packed with inspiring decor, the annual Hampton Designer Showhouse in Sag Harbor, NY challenged 26 local designers to fashion razzle-dazzle rooms to benefit Southampton Hospital for its ninth edition. Five of the stylesetters show us their sublime spaces, including a mod, pattern-filled living room by Pat Healing and Dan Barsanti of HB Home, Lisa Sternfeld’s charming top-floor aerie, a classic Hamptons kitchen from Robert Bakes and a beachy den by Patrik Lönn.
