Keyes Bungalow, California Bungalow architectural residence in Altadena, United States.

The Keyes Bungalow is a residential building in Altadena featuring California Craftsman architecture with a prominent shallow roofline that extends horizontally across the structure. The design emphasizes broad proportions and overhanging eaves that define its visual character.

The residence was added to the National Register of Historic Places in 1978 for its representation of early 20th-century Craftsman architecture. This recognition reflects the building's importance as a well-executed example of the movement's design principles.

Jackson Gregory, a writer of Westerns in the 1920s and 1930s, lived in the bungalow, and the house is noted for that association as much as for its architecture. It remains a private home, so the connection is read from the street rather than through a museum display. The name comes from the Keyes family, the home's original owners.

The building sits in a residential neighborhood in Altadena and remains a private residence with limited public access. Its exterior and architectural details are visible from the street, making it worthwhile for those interested in design and early 20th-century building styles.

The roof design was inspired by airplane forms, reflecting the early 20th-century fascination with aviation technology. This aircraft-influenced approach to residential design is uncommon and sets the house apart from typical Craftsman homes of the period.
