It holds an 1862 Greek Revival homestead and an 1880 Second Empire/Stick style mansion complex.","why_significant":"The property shows the shift from a simple 1860s homestead ranch into an elaborate residential estate built by San Francisco capitalist John A. Paxton in 1880. It holds one of the few remaining High Victorian villas of the 1880s. The design reflects the collaboration of Paxton with Santa Rosa designer/builder Thomas J. Ludwig.","narrative":"Perched on a knoll overlooking the Dry Creek Valley west of Healdsburg, this 7.92-acre rancho holds seven structures that trace a shift from frontier homestead to showpiece estate. The oldest is a one-and-one-half story Greek Revival farmhouse, believed built in 1862 by the Hooten family. In 1880 the capitalist John A. Paxton added a three-story mansion, a two-story carriage house and a pantry outbuilding, all built by Santa Rosa builder Thomas J. Ludwig. The mansion combines a Second Empire mansard roof with Stick style belt courses, Gothic Revival dormers and Eastlake trim, and it contains ten fireplaces, tiled floors and ornate brass hardware. The carriage house echoes these details. A schoolhouse is counted as a contributor, while a shed and a relocated cottage are non-contributors. Mature native trees fill the landscaped grounds. The district was recognized for its architecture and for illustrating how wealthy San Franciscans invested in Sonoma County in the 1880s.","period_of_significance":null,"architect_builder":"Thomas J.
