The underground mansion of an LA Shrimp tycoon built five storeys down into the bedrock Hacienda de la Paz City of rolling hills consists of just one gated community Maximum one-storey building code means you need to get 'creative' if you want to maximize space Took nearly 17 years to build and sits mostly underground Features include a five-story indoor tennis court, 25 bathrooms, a 10,000-square-foot Turkish bath In Los Angeles, the city of Rolling Hills could be its most exclusive. Consisting of a single gated community, there is a one-story height limit on houses, so instead of building up, you build down - deep into the bedrock. The story of Hacienda de la Paz and its owner John Z. Blazevich, who's the CEO of shrimp importer Viva Food Group, decided to build his mansion five stories underground - it's accessible by stairs and two elevators. Spreading over 50,000 square feet and on 7.27 acres, it was built over 17 years and overseen by Rafael Manzano Martos, a curator for King Juan Carlos of Spain. There are nine bedrooms, 25 bathrooms, secret passageways, a Moroccan-style Turkish bath and even an underground tennis court which could be yours for a cool $53 million.
