This huge waterfront mansion is located at 4449 Bay Shore Road in Sarasota, FL. It is owned by James and Maryann Armour and was styled after the Monte Carlo Casino. They purchased in 2008 for $19 million and they have spent millions on renovations since then. It boasts 21,192 square feet of living space and is likely the most expensive and largest home since John Ringling built his Ca’ d’Zan estate in 1925. It boasts 22 rooms with 11 bedrooms, 12 baths and three half-baths, media room, a grand salon, a dining room, a fitness center, a “kids’ rec room,” a study, staff quarters, guest quarters, a master bedroom/sitting room the size of a cottage, a master closet that could pass for an apartment in Manhattan, and a “file room.” The total building area tops 39,000 square feet.
