The Adamson House and its estate, known as Vaquero Hill in the 19th century, is a historic house built by Rhoda Adamson and gardens in Malibu, California. The residence and estate is on the coast, within Malibu Lagoon State Beach park.

It has been called the "Taj Mahal of Tile" due to its extensive use of decorative ceramic tiles created by Rufus Keeler of Malibu Potteries. The house was built in 1929 for Rhoda Rindge Adamson and Merritt Huntley Adamson, based on a Mediterranean Revival design by Stiles O. Clements of the architectural firm of Morgan, Walls & Clements. The Adamson House was designated as California Historical Landmark No. 966 in 1977, and added to the National Register of Historic Places in 1985.

Frederick Hastings Rindge was a wealthy Boston businessman who relocated to Los Angeles, and owned the "Rindge Ranch", which included the historic Spanish land concession Rancho Topanga Malibu Sequit, enlarged by subsequent land purchases surrounding the ranch. The Rindge Ranch thus encompassed present day Malibu, California, and small portions of the Santa Monica Mountains. His daughter was Rhoda Agatha Rindge Adamson.

Merritt Adamson (1888–1949) was a graduate of the University of Southern California Law School and was the captain of the 1912 football team, the first USC team to be known as the "Trojans". Adamson met Rhoda Rindge while he was employed as the foreman of the Rindge Ranch. Rhoda Rindge reportedly became interested in him when she helped nurse him back to good health after he was injured in an accident. The couple was married in 1915. In 1916 Adamson established a dairy business in the San Fernando Valley, in Tarzana known as Adohr Farms, the name being his wife's name spelled backwards. The business became one of the country's largest dairies, operating one of the largest herds of Guernsey cows in the world.

The two-story, ten-room Adamson House was designed by Stiles O. Clements and built of steel-reinforced concrete. Completed in 1930, Stiles called the house an outstanding example of modified Mediterranean Revival-style architecture. Architectural historians refer to the style as a synthesis of Spanish Colonial Revival and Moorish Revival architecture. The interior features red tile floors, lancet windows, tile roofs, wood beams and molded walls. The house features teak woodworking, fireplaces in several interior and outdoor patio rooms, handpainted ceilings, lead-framed bottle glass windows, and "wrought-iron filigrees fitting over the windows like intricate jewelry." The main floor is dominated by a large living room with windows on three sides. The room is still furnished as it was when the Adamsons lived there, including the large radio on which the family received news of the attack on Pearl Harbor. Other rooms on the main floor include a guest bedroom with a bathroom that is tiled literally from floor to ceiling, a dining room with an old convent table overlooking the ocean, a kitchen with an early version of a dishwasher and a colorful tiled clock, and the main entrance with its imposing wood door and tiled entrance table. The house also features an elevator system.

There are four bedrooms and a small kitchenette upstairs. The master bedroom, where Mr. and Mrs. Adamson slept, is on the southwest corner of the house. It has a large tiled bathroom, and Mrs. Adamson's clothes and hat collection remain in her closet. Next to the master bedroom is the one designed for the Adamsons' son; its bathroom has detailed tiles depicting ships and nautical scenes. The girls' bedroom in the center facing the ocean has a tremendous view of the ocean and coast. These three bedrooms open onto a large upstairs patio with the home's most spectacular panoramic view of the ocean, the Malibu lagoon and the coast in both directions. The fourth bedroom upstairs is at the eastern end of the second floor and looks out of a large Dombeya tree that blooms with spectacular bright red flowers in the spring.

Another striking feature of the house is the tiled swimming pool set into the sand that was equipped with a special filtering and heating apparatus that permitted the pool to be filled with either salt or fresh water. The Los Angeles Times in 1930 noted that the unusual features made the "plunge one of the finest in the southland."

Adamson House is best known for its extensive use of locally produced Malibu tile. In 1926, May K. Rindge (Rhonda Rindge Adamson's mother) established a tileworks east of the Malibu Pier. The factory was run by Rufus Keeler, an innovative ceramic engineer, who worked with local artisans to design decorative art tile, employing more than 100 persons in the late 1920s and creating "some of the most colorful and inventive glazed tiles in the country." Hand-crafted art tile fired from local clay was specially designed for each room of the Adamson House. Even the ceiling of one of the bathrooms was tiled. In 1930, the Los Angeles Times reported: "Striking tile effects have been obtained from original designs of the craftsmen and artists of the pottery and floors, walls and patios." Sixty-seven years later, the Los Angeles Times was still writing about the home's extraordinary tilework: "This huge Spanish-style mansion, built in 1929 (sic), might as well be called the house that tile built. Tile is everywhere — from the ceramic wall clock above the tile-topped oak table in the kitchen to the floor-to-ceiling tiled bathrooms."
