For potential home buyers, Silicon Valley in Santa Clara County is an area with prime real estate. Extravagant and pricey mansions compete easily with luxury estate from Beverly Hills, New York and even neighboring San Francisco, CA.

In early 2011, and out of fun and interest in the Silicon Valley real estate luxury market, I took the initiative to list on this page some of the top high-end luxury homes for sale on the Silicon Valley market at that time. As you may suspect, these dream homes were located primarily in Los Altos, Los Altos Hills, Saratoga and Palo Alto.

A Real Estate blogger from Burbed elaborated on this page and provided excellent insights into each property. You can read all about it here.

For the record, as of June 2012, the majority of the 2011 listings either expired and were removed from the market. Only a few of them are still on sale (some with a reduced price) and only one sold at the asking price. You can find the original page for Astonishing Homes for Sale in Silicon Valley in 2011 right here.

By popular demand, here are below some of the most astonishing luxury homes for sale in Silicon Valley in 2012.
