A newly built mansion on Golden Beach’s exclusive Ocean Boulevard has sold for $69.5 million in an all-cash deal, closing out a five-year journey that began with a $10.7 million vacant lot and ended with a 17,500-square-foot spec estate designed for the ultra-wealthy. The buyer, an entity called Meridian Coast LLC, is keeping its identity under wraps.
The sale, first reported by The Real Deal, was managed by a company tied to Ricardo Halfen, the spec home developer who serves as CEO of Treo Construction. Halfen and his wife, architect Stephanie Halfen of SDH Studio, acquired the then-vacant 0.65-acre site through the entity 255 OB LLC in April 2021 for $10.7 million, buying it from a trust managed by Lorena Zuccolillo, daughter of late Paraguayan media entrepreneur Aldo Zuccolillo, according to SDH Studio. The 255 OB LLC entity, based in North Miami Beach, is managed by Halfen alongside Tania Van Dam Murciano, per the same Real Deal report.
The finished estate spans roughly 17,500 square feet with seven bedrooms and 12 bathrooms, sitting on a 0.7-acre lot with 100 feet of waterfront. The property includes a guest house, a pool and a spa, the report notes. Additional amenities described in earlier marketing materials — including a rooftop pool and spa, a 75-foot lap pool, a private movie theater, and a wellness wing with a sauna and cold plunge pool — were highlighted in a Home Stories AI video tour of the finished home.
A Steep Discount From the Original Ask
The estate first hit the market in February 2026 asking $88.5 million, before most recently listing at $79.5 million. It ultimately sold for $69.5 million — a 20 percent discount off that original asking price, The Real Deal reported.
