About this property
A truly exceptional Miami Modern Tropical residence set on a prime 8,010 SF corner lot, offering 3,549 SF of beautifully curated living space with 4 bedrooms and 3.5 bathrooms. Designed by architect Hervin Romney, a founding member of Arquitectonica, the home reflects a distinctive architectural vision inspired by the organic principles of Frank Lloyd Wright and the expressive forms of Antoni Gaudi, where art, design, and nature seamlessly converge. This residence captivates with its abundance of natural light, soaring high ceilings, fluid open spaces, and harmonious lines that create a sense of warmth, sophistication, and effortless flow throughout the main living areas. The beautifully remodeled kitchen and bar are a true centerpiece, featuring high-end appliances, premium finishes, refined craftsmanship, and a design that balances functionality with striking aesthetics. Step outside into your own private tropical retreat, where lush landscaping, graceful curved terraces, and a stunning swimming pool create an atmosphere of tranquility and escape.
