Palm Beach has quietly unveiled one of the most significant private estate transformations in its history — and it’s now Margit Brandt’s biggest listing yet, coming to market at $175 million.
Known as Casa del Ensueños, this newly completed, landmarked waterfront estate sits in the heart of the Estate Section at 800 S County Road. Set on a nearly 1.5-acre parcel with approximately 250 feet of direct Intracoastal frontage, the property spans roughly 27,111 total square feet — a scale that’s become exceptionally rare on the island.
Originally built in 1928 and now fully reconstructed through a multi-year, ground-up reimagination, the historic Mizner residence has been transformed into a modern Palm Beach compound that has never been lived in, pairing classic Venetian-style architecture with today’s infrastructure, finishes, and systems.
The gated estate unfolds across a main residence, boathouse, tennis pavilion, and a six-car garage, delivering 15 bedrooms, 18 full bathrooms, and 5 half baths, with approximately 21,534 square feet of interior living area.
Amenities go deep: an expansive covered loggia, chef’s kitchen, a full performing arts theater with stage, elevator access, eight fireplaces, a comprehensive security camera system, generator, and a newly constructed seawall. Outdoors, the estate leans into resort-level living with refined landscape lighting, a heated infinity pool with swim-resistance jets, and a private, sunken red-clay tennis court embedded within the grounds.
Directly on the Intracoastal, Casa del Ensueños includes private docks and a 40,000-pound boat lift, combining true boating access with the privacy and western exposure that set Palm Beach sunsets apart. And while it feels tucked away, it’s still minutes from Worth Avenue, Mar-a-Lago, and the rising energy of downtown West Palm Beach’s “Wall Street South” corridor — plus beach access just steps away. With its frontage, acreage, fresh reconstruction, and island positioning, Brandt’s $175 million listing reads like a once-in-a-generation Palm Beach compound.
