A one-of-a-kind Miami Beach estate at 123 Sunset Island Drive has hit the market for $33.5 million, representing a pinnacle of custom design where no expense was spared. Unlike a speculative-built ("spec") home constructed for the general market, this property was meticulously crafted over years by its owner to fulfill a singular personal vision. Featuring rare materials like rose onyx walls and Napoleon red marble, the home is a testament to bespoke luxury on one of Florida's most exclusive man-made islands.
What Makes This Sunset Island II Property Unique?
The defining characteristic of this nine-bedroom, 9.5-bathroom estate is its origin as a deeply personal project for the current owner, event company proprietor Barton G. Weiss. According to listing agent Danny Hertzberg of the Jills Zeder Group at Coldwell Banker Realty, "This is the polar opposite of a spec home." Weiss acquired the property from his parents in 2004, razed the existing structure, and spent over 15 years creating a residence tailored to his exacting standards. The result is a 12,190-square-foot primary residence with a two-story guesthouse, where every detail is a custom selection, from the unique light fixtures to the globally sourced exotic stones. This level of customization means the home is not designed for every taste but stands as a unique artifact of individual design passion.
What Are the Standout Design Features and Materials?
The home's interior blends a modern contemporary style with Art Deco influences, creating a dramatic contrast with its traditional Mediterranean exterior. Upon entering, a two-story foyer features an immense reverse-wedding cake chandelier and a sweeping staircase flanked by art pieces. The living area is highlighted by a full wall of rare rose onyx, with concealed shelving and an entertainment center. A hidden speakeasy bar, crafted from striking Napoleon red marble, features a one-of-a-kind lily-shaped chandelier and a hand-painted ceiling embedded with crystals. High-end materials extend to functional spaces; the kitchen boasts emerald-green quartz countertops and gray-blue limestone floors, while the primary suite bath features floor-to-ceiling Egyptian onyx alabaster and the bedroom has walls upholstered in Spinneybeck leather.
What Amenities Does the Property Offer?
Beyond the architectural grandeur, the estate is designed for luxurious indoor-outdoor living synonymous with South Florida.
The location on Sunset Island II, one of four man-made islands developed in the 1930s, offers a private park and a bridge connection to the vibrant restaurants, shops, and white-sand beaches of Miami Beach. The island has been home to numerous celebrities, adding to its cachet.
Who is the Target Buyer for This Type of Home?
This property appeals to a very specific buyer seeking a turnkey, custom-designed masterpiece rather than a project. It is ideal for an individual who appreciates artful, bold design choices and values the history of a home created with an uncompromising vision. As Hertzberg notes, "The owner has a keen eye for design... willing to invest in the execution." The buyer must value the private, gated location, the unparalleled quality of the finishes, and the unique beauty that distinguishes it from any other property on the market.
In summary, purchasing this home is about acquiring a piece of curated art and architectural history. Key considerations for a potential buyer include:
