It is also described as a transitional work in Birge Clark's career and a forerunner of his later Norris residence. The two houses were expected to influence local architecture.","narrative":"Dunker House is a 1926 residence at 420 Maple Street in Palo Alto, set at the end of the street beside San Francisquito Creek in the Crescent Park subdivision. Architect Birge M. Clark designed it for Mr. and Mrs. John Dunker, with Wells Goodenough as builder and Leslie Kiler as landscape architect. The house runs more than 100 feet along Maple Street and encloses a patio on three sides, with a long cloister on the west and a two-story wing with a balcony and arched solarium windows on the east. Interiors include wide plank oak floors, textured plaster, and a beamed cathedral ceiling in the living room. The nomination describes it as one of the first two Palo Alto houses in the Early California style, built at the same time as the Pettigrew house by George Washington Smith. It also marks a transitional point in Clark's career and is described as an ancestor of the later Norris residence. The house is in excellent condition and largely unaltered.","period_of_significance":"1900- (specific date 1926)","architect_builder":"Birge M.
