Jill Hertzberg and Danny Hertzberg of The Jills Zeder Group for Coldwell Banker Realty in Miami have closed another record. This time it was for a nearly complete 2026-built Indian Creek Island estate for $170 million, the most expensive residential transaction in Miami-Dade County history, according to media reports.
Listed in November 2025, the waterfront mansion sold in a matter of months, an unprecedented turnaround for transactions in the ultra-luxury segment.
The limestone-clad estate was conceived by Ferris Rafauli, the Toronto-based designer known for merging architecture, interiors, and sculptural art into a single cohesive language. At nearly 28,000 square feet, the residence layers monumental scale, precise geometry, and luxuriously tactile materials such as limestone, suede, lacquer, and bronze—all Rafauli signatures.
Spread across nearly two acres with 200 feet of Biscayne Bay frontage, the residence is designed to dissolve the boundary between indoors and out. Serenity comes from the uninterrupted water views; drama comes from the bespoke craftsmanship.
The amenity program rivals that of any five-star resort: a jazz lounge, a double-height library reached via a hidden passage, and a 1,500-gallon aquarium suspended between the kitchen and dining room. A spa suite with a Himalayan salt-wall sauna and steam room anchors the wellness wing. A sprawling primary wing spans half of the second floor, completing the nine-bedroom home.
Outside, the estate becomes an all-season retreat. A 60-foot pool, an elegant cabana, and a 135-foot dock stretch out toward open bay views.
Jill Hertzberg called the property "a new benchmark for exclusivity and craftsmanship" when it listed last November. At $170 million, the case has been made. It is one of several Miami-area nine-figure closings in the past eighteen months, a streak that has left little doubt about where Miami now stands among the world's luxury markets.
