With its show-stopping blend of Old World architectural marvels and modern-era splendor, the famed Nero Estate stands alone as a true residential original in South Florida. The Sanctuary, a private enclave of luxury estates along the Intracoastal in Boca Raton, provides the exclusive backdrop for this 15,856-square-foot masterpiece, nestled on a coveted lot with 258 feet of water frontage. The seven-bedroom, eight-bath (with three half-baths) double-lot property, brimming with rare artisanal details, finds inspiration everywhere from Western Asia to Europe to the Windy City.The design drama begins in the grand rotunda, an entrance that includes a 12-foot-tall antique, handcrafted wood door.
