Amazon.com founder Jeff

Bezos has gone shopping on the Westside, buying a home for $12.9 million in a deal completed offmarket.

Never publicly listed for sale, the 1956-built house sits on a halfacre lot that backs up to the Spanish-style estate that Bezos bought in 2007 for $24.45 million.

In other words, it’s a real-world firewall for the multibillionaire.

Details are few and far between, but tax records show that the home has 4,586 square feet of interior space on one level. Formal living and dining rooms, four bedrooms and six full bathrooms are among the living spaces. There are two fireplaces.

Mature trees, patio space and a swimming pool fill the backyard. A motor court with two gated entrances marks the entrance to the property. Combined with the neighboring estate, the two properties total about 2.5 acres.

Bezos, 53, founded Amazon.com in 1994 and owns nearly 81 million shares in the company. With a net worth of about $85 billion, he is among the richest people in the world.
