Hacienda de la Paz is a large estate property in the city of Rolling Hills, on the Palos Verdes Peninsula in the Los Angeles area of Southern California. It was designed by the 2010 Driehaus Prize winner Rafael Manzano Martos with decorator Manuel Gavira Sanjuan for owner/builder and is Martos' only project in the Americas. Construction began with two parcels of land in 1993 and final completion was not until 2008. It is the 36th largest home ever built in the United States, still standing, and the only Spanish Colonial Revival on the list.
