The long-time Silicon Valley estate of billionaire Marc Andreessen has suddenly become available for $33 million.

Currently, Marc Andreessen has properties in Malibu valued at over $255 million. These assets include a 13-building complex in Paradise Cove and an adjacent $34 million property, as well as a $44.5 million residence on nearby Escondido Beach. It’s therefore not totally shocking that the tech, crypto, and venture capitalist billionaire has chosen to put his long-term Northern California home up for sale given that he now spends a substantial amount of time in the beachside SoCal city.

The asking price is just over $33 million, which is almost twice as much as what the late Silicon Valley philanthropist and multibillionaire John Arrillaga’s wife, Laura Arillaga, and co-founder of Netscape and venture capital firm Andreessen Horowitz paid for the property in early 2007.

The gated 1.5-acre property in the affluent Silicon Valley enclave of Atherton was completed in the mid-1990s by custom builder Colin Whiteside, but underwent extensive renovations over the course of the couple’s stay. The main Tuscan-style mansion, along with a guesthouse and separate office/studio, totals five bedrooms and seven bathrooms in a little more than 12,400 square feet.

A circular driveway fronts the primary residence, which is distinguished by an expansive terrace lined with carved balustrades and topped by balconies. Once inside, a foyer displaying herringbone-style cherry floors and a sweeping staircase greets and flows to three-story living space highlighted by an elevator to all levels, seven fireplaces, and high-tech home-automation, security and surveillance systems.

In addition to a living area boasting soundproof suede walls, automated window shades, a concealed projector and retractable cinema screen, other highlights include a formal dining room served by two kitchens outfitted with a suite of top-tier Bosch, Hestan, Kitchen-Aid, Miele, Sub-Zero and Wolf appliances, as well as a family room that opens to a covered terrace sporting a built-in barbecue. The standout features continue with a den that has an adjoining office, recreation/media room, mirrored gym, and an upstairs lounge that connects to a sumptuous primary bedroom decked out with a private balcony, dual walk-in closets, and a luxe marble-clad bath spotlighted by a spa tub and curbless shower.

Outside, a blend of artificial and natural grass lawns adorn the well-kept surroundings. has a media room shaded by an arbor, as well as gardens, fountains, and specimen trees. In addition to the aforementioned, the property has an office/studio with a kitchenette and complete bathroom, as well as a guesthouse with one bedroom, one bathroom, and its own living area and kitchen. Additionally, there is a three-car garage with a fourth bay that has been turned into a catering area and office.

Andreessen, whose net worth is now estimated at $1.9 billion, is said to hold a $36 million vacant site just outside of Las Vegas in addition to his houses in Malibu and Atherton.
