Description: This is one fabulous beach house -- something akin to Xanadu on the dunes. In the front it overlooks the Intracoastal Waterway, and it has the Atlantic at its back door.
Built in 2006, its features include an abundance of marble and hardwood, coffered and vaulted ceilings, custom drapes, a swimming pool, hot tubs and gorgeous landscaping.
