Palm Beach Oceanfront Estate Lists for $110 Million on Billionaires' Row

A Mediterranean-style oceanfront estate on Palm Beach's exclusive Billionaires' Row has been listed for $110 million, making it one of the most prominent residential offerings in the United States in 2026. The property, known as Pietra Mare, spans over an acre and features 170 feet of direct beach frontage, positioning it as a landmark opportunity for luxury real estate investors and high-net-worth buyers seeking a premier Florida compound.

What are the key features of this $110 million Palm Beach property? The 28,399-square-foot mansion is a custom-built residence completed in 2003. It includes seven bedrooms, nine full bathrooms, and six half-bathrooms. The home's oversized rooms are characterized by soaring ceilings, stone floors, and walls of arched windows that maximize ocean views. The layout begins with a dramatic, double-height formal entry hall with a patterned floor and ornate staircase. Key living areas include an expansive living room with French doors opening to the grounds, a wood-paneled library with built-in shelves and a fireplace, a formal dining room, and a bright, white kitchen that flows into a glassed-in breakfast room. The primary bedroom suite upstairs features a private balcony and a luxuriously large bathroom.

What is the history and ownership background of the estate? The estate is reportedly owned by securities systems executive Edward “Chris” G. Watkins, who purchased the property in 2001 for $17.7 million, according to public records. He then commissioned the custom-built mansion on the coveted parcel. The property was first marketed as a quiet, off-market listing—often called a whisper listing—at $105 million before being officially listed in 2018 for $109.5 million. After a period off the market, it has returned in 2026 with a slight price adjustment to $110 million. A whisper listing is a property marketed discreetly without a public listing on major real estate platforms, typically to maintain privacy for high-profile sellers.

What amenities are included in the landscaped grounds? The over-one-acre lot is meticulously landscaped with towering palms and a grassy lawn that leads to the beach. Outdoor amenities are extensive and designed for luxury living and entertaining. They include a swimming pool, a spa, and a covered outdoor space for dining and lounging. A significant feature is the separate guesthouse, providing additional privacy for visitors. The property also offers deeded beach access, meaning ownership includes the legal right to use the 170 feet of private beach frontage. Other property perks include parking for six vehicles, an elevator, a wet bar, a whole-house sound system, and a private gym.

How does this listing fit into the current Palm Beach luxury market? Based on our experience assessing the Palm Beach market, properties of this caliber on Billionaires' Row are rare, with location and irreplaceable oceanfront acreage being the primary drivers of value. The property's location about a half-mile south of the Mar-a-Lago club underscores its position in an ultra-exclusive enclave. The slight price increase from its 2018 listing reflects a market trend where unique, trophy assets with no comparable substitutes can see appreciating value over time, even amid broader market fluctuations.

For prospective buyers, the combination of total privacy, extensive indoor-outdoor living spaces, and direct ocean access represents a compelling investment. The inclusion of a guesthouse and extensive amenities creates a turn-key compound for full-time residence or seasonal use. The key takeaway is that such iconic properties are valued for their land, location, and legacy, often transcending typical market metrics.
