The Wall Street Journal's Market Watch recently reported that the $100-million sales price of the single-family residence in the Silicon Valley, purchased by Internet mogul Yuri Milner, is the highest known amount paid for a house in the U.S. The story was first reported last week by technology blog TechCrunch.

Is the price correct? With various resources reporting the actual sales price ranging between $70 million and $100 million, it was questioned. However, according to a report filed by the San Francisco Examiner, the $100 million sales price is based upon the $110,000 transfer tax recorded by the Santa Clara County Assessor's office. So, yes the price is right.

The 18th century-styled French chateau has 25,500 square feet of living space in a floor plan that includes five bedrooms, nine bathrooms, a ballroom, a home theater, a wine cellar, an indoor swimming pool and a gym with a spa. The exterior of this 18-acre stupendous dwelling has pristine gardens, an outdoor swimming pool, a tennis court, and a private car wash. The everyday living sections of the estate are located on the second floor to take in the picturesque view it offers looking out at the San Francisco Bay.

While Milner, the founder of Internet investment company Digital Sky Technologies and chairman of Mail.ru Group, plans to keep his primary residence in Russia, his intentions at this time with the residence are unknown.

Hablinksi + Manion Architectural & Planning Group designed the $100-million estate for the original owner and seller, Fred Chan, the founder of ESS Technology.
