A prime example of Altadena’s finest historical mansions, 1051 was built in 1915 for fashion designer Kate Duncan. Duncan’s family states the architect was never known to them, though Kate’s first home was a Greene & Greene, built in 1906 and now known as the Duncan/Irwin House. Architectural historian Tim Gregory notes that the Kate Duncan House was identified by Altadena Heritage in the 1980s as potentially eligible for listing in the National Register of Historic Places and the Calif. Register of Historical Resources due to its fine design in the Prairie School style (rare in Southern Calif.) its historically significant owners, and its contribution to the historical and architectural context of its Altadena Drive neighborhood. Built on a grand scale with many original features intact, the 5,372 s.f. home possesses a Frank Lloyd Wright-inspired floor plan, with one room flowing into another, making it perfect for entertaining and living in style. The home is set back from the Drive on a raised 23,198 s.f. park-like corner lot and generously insulated. Undergirded with massive Redwood beams, 1051 was restored to its authentic Prairie-Style color palette and architectural details by its current owners.
