This $49 Million Atherton Compound Is a Self-Contained Resort with a Guest House, Spa, and Sports Complex

In Silicon Valley’s most exclusive zip code, a brand-new 16,942-square-foot modern masterpiece is redefining what it means to live large—even by Atherton standards.

Just completed in 2025, this one-of-a-kind modern estate is as much a statement of craftsmanship as it is of scale. Spread across three levels, the residence unites grand architectural gestures with warm, livable design. Think sleek gallery-like spaces softened by organic textures and expansive glass walls framing private, manicured gardens. Joe Piazza of Coldwell Banker Realty in Los Gatos, who holds the listing, calls it an "extraordinary opportunity to own a one-of-a-kind modern estate in the heart of Atherton." He’s earned the authority to say so—Piazza has ranked among Silicon Valley’s top-producing agents for more than a decade.

Set on 1.42 acres within a gated, park-like enclave surrounded by $30 million to $60 million estates, the property is a compound in every sense—its privacy enhanced by lush landscaping and resort-caliber outdoor amenities. Every detail underscores the developer’s “uncompromising commitment to quality and craftsmanship”—from the precision of its millwork and stone selections to its world-class home automation and security systems. Six fireplaces thoughtfully placed throughout infuse the interiors with warmth and intimacy.

The property comprises nine bedroom suites, twelve bathrooms, and three elegant powder rooms. The main residence features not one but two primary suites, each designed as a private sanctuary. For entertaining, the main level unfolds with effortless flow: an exquisite living room, grand great room, and formal dining space all connect to an open-concept, state-of-the-art kitchen. 

Below grade, the estate’s resort-style amenities unfold in a series of luxurious spaces for relaxation and recreation—a home theater, wine cellar, spa, gym, and library. 

Outside, the estate feels like its own private country club. A detached guest house and separate pool house overlook a resort-style pool and spa, while a tennis court, basketball court, curated gardens and firepits invite relaxation and recreation in equal measure.

Priced at $49,888,000, it's a modern architectural tour de force that combines technological sophistication with the ultimate in gated privacy. A rare offering even in Atherton, where perfection is the standard.
