Set on an oversized 9,000 SF lot, the residence offers 6 bedrooms, 6 full bathrooms, 1 half bath, and over 4,190 SF of curated living space designed around natural light, privacy, and seamless indoor-outdoor living.
Imported Spanish porcelain and ceramic surfaces, Italian-engineered wood flooring, Portuguese interior doors, and refined finishes sourced from the United Kingdom create a warm and sophisticated architectural atmosphere throughout.

Located moments from tennis courts and the Key Biscayne Yacht Club, beaches, marinas, top-rated schools, and the best of island living, this residence represents one of Key Biscayne’s most thoughtfully designed brand new-construction homes - Expected to be finished in July 2026. Easy to Show!
