8. The Spelling Manor, Los Angeles, California
The French-chateau style Spelling Manor was built in 1988 and is located in Holmby Hills in the neighborhood of Los Angeles. It is built on 4.6 acres of land and consists of nearly 123 rooms that make it the largest home in Los Angeles. The manor once belonged to Aaron Spelling, who was a very famous and one of the richest television producers. Presently, the owner of this opulent dwelling is heiress Petra Ecclestone, who has put up this expensive house for sale for about $150 million.
The current value of the house has made it the most costly homes in the real estate listings of USA. However, the house has always been on and off the sale due to controversies, associated with its wrong positioning, as it is built in the area, which is not meant for building huge mansions.
