Nestled on the outskirts of San Francisco and Stanford, Green Gables is a sight to be seen, and is soon set to become Silicon Valley's most expensive home. The century-old estate spans 74-acres of Californian foothills, includes 7 properties, 3 swimming pools, a garden brimming with roses, berries, and dahlias, a reservoir, barn and stables - oh, and just some of the most insane panoramic views of the Santa Cruz mountains around. Plus 29 bedrooms and 25 bathrooms, though who's counting?

Originally built in 1909 as the summer home of businessman Mortimer Fleischhacker, Green Gables is expected to go for around $140 million.
