Robert R. Blacker House, Arts and Crafts residence in Hillcrest Avenue, Pasadena, United States.

The Robert R. Blacker House is an Arts and Crafts residence on Hillcrest Avenue in Pasadena, California, set on a generous lot with terraced gardens. The interior displays teak paneling, mahogany doors, and handcrafted woodwork throughout its rooms.

Robert Roe Blacker, a retired Michigan lumberman, had Greene and Greene build the house in 1907 after dismissing Myron Hunt and Elmer Grey over disagreements. The brothers called it their masterpiece, and it was their first house to use many exotic woods, including Honduras mahogany, Burmese teak and ebony. It joined the National Register of Historic Places in February 1986.

Robert Blacker's background in the lumber trade shaped the house: Greene and Greene could use a wide range of exotic woods here, including Honduran mahogany, Burmese teak, ebony, and fine redwood and Douglas fir. The furniture, light fixtures, and even garden vases were designed and made by hand for the house.

The estate remains in private hands and is not usually open to visitors. Occasional tours organized by local groups offer a chance to see the interior and gardens.

When original light fixtures and other elements were removed in 1985, the city responded with the Blacker Ordinance. This new rule now protects historic architectural components in other buildings across the city from similar loss.
