This rare residence in Key Biscayne’s uber-prestigious Mashta Island just set a new all-time record for the priciest non-waterfront new construction home.

Selling for $7.3 million at $1,728 price per square foot, the home at 730 N Mashta Drive was under contract in just two and half months, the result of a connection made by agent Joan Bruggink with ONE Sotheby's International Realty who represented the seller in the transaction. 

Spanning 4,225-square feet of interiors with six en-suite bedrooms, the property is an architectural marvel. The expansive open floor plan showcases soaring 21’ ceilings and telescopic sliding doors that create a seamless flow between the indoors and outdoors. A third floor rooftop terrace showcases astounding Miami sunsets.

The interiors boast a dining room complete with a 288-bottle glass wine vault and a gourmet kitchen with Miele and Bosch appliances, porcelain and quartz countertops, plus a kitchen bar. The master suite is complete with a spa-like bathroom plus his and hers closets. Outside, the space is adorned by a lush garden, heated pool and BBQ gazebo. Additional amenities include an office, laundry room, storage and 2-car carport garage.
