About the home

Set on one of the largest lots in Key Biscayne, a rare 12,200 sqft parcel, this colonial-style residence, known as Villa Rosa, was designed by renowned architect Cesar Molina and sits on a quiet, low-traffic street in a well-established, family-friendly neighborhood. The generous lot allows for a spacious backyard with pool and abundant green space, ideal for outdoor living and entertaining. Double balconies and covered terraces create a seamless indoor-outdoor flow throughout the home. This 5-bedroom residence offers bright interiors and a chefs kitchen with island, Sub-Zero refrigerator, wine cooler, double ovens, and two dishwashers. The primary suite includes a private terrace, oversized walk-in closet with safe, and dual baths with sauna. Also includes maids quarters and hurricane code construction. Minutes from the beach, parks, and top schools - a rare opportunity to own a well-designed home with an exceptional lot on one of Key Biscayne's most desirable streets.
