The 11,000 square foot mansion at 221 Casuarina Concourse has a waterfront spot on Lago Monaco and is just blocks from Biscayne Bay. The $9.9 million Coral Gables estate is an 8-bed/10-bath, two-story behemoth spread amongst nearly an acre of prime Miami real estate. Built in 2000, the home has a private boat dock on the lake/lagoon and a heated swimming pool and a driveway and parking loop decked in charming, rustic pavers. Hardwood floors bedeck the interior floor plan, which includes a movie theater, game room and two master bedroom suites. [via realtor]
