In the real Orange County, not everyone ends up living in their custom-built home.

The Kristin Cavallari family residence, eight years in the making, has come on the market at $13.95 million in Three Arch Bay, a gated Laguna Beach community.

Kristin was playing herself in 28 episodes of "Laguna Beach: The Real Orange County" (2004-05) during part of the construction period but never occupied the feng shui-certified residence. And in what may seem to blur the lines of reality with reality TV, the home was designed by architect Jim Conrad, father of fellow cast member Lauren Conrad, who went on to star in "The Hills" (2006-08).

The newly built contemporary has four bedrooms and six bathrooms in 7,100 square feet and sits on 3.25 acres with views of Catalina and the coastline. Natural stone -- more than $2 million was spent on masonry alone -- and hardwoods were used extensively in the construction. There is an infinity pool, nearly an acre of landscaped grounds and gardens, and on-site parking for 25 cars.

Kirstin, 22, became a spokeswoman for the clothing company Bongo and continues to act in film and TV, as well as host and play herself in reality shows.

Chris Guziak of Coast Sotheby's International Realty, Laguna Beach, has the listing.
