This mega waterfront mansion, located on Bay Lane in Key Biscayne, FL, is owned by¬†Edgardo and Ana Cristina Defortuna. Edgardo is a prominent real estate developer (has built hundreds of condos in Miami) and is the founder of Fortune International Realty. The couple purchased the property in 2002 for $5.4 million. At the time, former president Richard Nixon’s compound, dubbed the “Winter White House”, occupied the land. They initially wanted to expand the property but ultimately ¬†tore it down. Then in 2005 they purchased an adjoining property for $8 million to make one big property. They built this huge 22,000 square foot mansion in its place. All in all they spent around $20 million to build their dream home. The home features 3 gated entrances, a courtyard 6 bedrooms, rotunda foyer with 26 foot ceilings and Y-shaped marble staircase, formal reception rooms, a “quincho” (Argentine term for a covered barbecue area), gym, spa, playroom, beauty salon, infinity swimming pool and more.
