500 S Mastha Dr via Sotheby's
Built down the street from the record $47-million sale at Mashta Point is this freshly listed six-bedroom, eight-bathroom (two half-baths) home at 500 South Mashta Drive magnificently designed by Venezuelan architect Oscar Capiello.
Constructed in 2014, its most compelling feature has to be the three-story curved glass wall displaying panoramic views of Biscayne Bay from the living room and master bedroom. It also has folding glass doors, a glass and steel interior bridge, gym with ocean views, and state-of-the-art smart home technology. At 11,149 square feet sitting on a 23,800-square-foot lot, this is Key Biscayne's third most expensive home for sale. It last sold for $6.6 million in May 2009.
