    What's special

    Exceptionally-positioned Mashta Island waterfront residence, integrating modern lines and brilliant Calacatta marble floors throughout. An elegant ambience that faithfully showcases the light-filled voluminous spaces that are the signature design of esteemed Miami architects Brown L. Brown. This rare property is additionally enriched by an expansive field-sized private garden and professionally-illuminated mature tall-tree canopy; all entirely safeguarded by video-camera surveillance. The residence, with family environments positioned above 10-feet of elevation, is situated on a secluded waterfront cove that is naturally insulated from inclement weather; enabling secure on-site yacht dockage, while also providing quick access to both Biscayne Bay and the Atlantic Ocean. Uniquely, the property is further distinguished by spectacular half-a-mile depth of water-views from within the residence ... a captivating horizon that broadly extends across Key Biscayne's protected and picturesque "South Basin" marine inlet, and onward to the tranquil greenery of Bill Baggs Cape Florida State Park.

    This property is off market, which means it's not currently listed for sale or rent on Zillow. This may be different from what's available on other websites or public sources.
