“Never more, never less.” That was the trademark philosophy of legendary interior designer Albert Hadley, who masterfully shaped high-society taste for decades. Before his passing in 2012, he crafted iconic spaces for Jacqueline Kennedy Onassis—including the White House breakfast room and her famed red Park Avenue library—as well as Oscar and Annette de la Renta, Diane Sawyer, and the Rockefeller, Mellon, and Getty families.

One of Hadley’s lesser-known projects can be found in the southwest Florida city of Naples, about two hours from Miami, where he spent part of the late 1990s and early 2000s tailoring a charming coastal cottage and guesthouse to serve as his winter retreat. Filled with personal collages, historical bibelots, and furnishings culled from his other homes, the curated display was featured in major shelter magazines, from House Beautiful to House & Garden.
