It was laid out in 1912 by Harry Richardson and contains houses in Bungalow/Craftsman, Cottage Revival, Colonial Revival, Mission Revival, Prairie School, Tudor Revival, Four Square and Ranch styles.","why_significant":"The district is argued to be significant under Criterion C for Architecture for its range of early 20th century styles, particularly its Bungalow/Craftsman homes, and for its curving street pattern and deed-restricted suburban layout. The nomination also presents it as an example of early suburban development shaped by the Lehigh Transit Company trolley line and the growth of Lansdale.","narrative":"Laid out in 1912 in Hatfield Township about one mile from downtown Lansdale, Oak Park is a planned residential district of early to mid 20th century houses. Developer Harry Richardson sold lots with deed restrictions that set front setbacks at 75 feet and banned noisy or odorous businesses. The narrow, winding streets, including a landscaped median on Oak Boulevard and a triangular garden on Park Avenue, were designed to contrast with the grid of Lansdale. The district includes eight Bungalow/Craftsman homes built from 1912 to about 1920, among them Richardson's own first house at 110 Oak Boulevard. Other notable buildings include a Mission Revival house at 136 Oak Boulevard and a Prairie School music conservatory at 1020 Forest Avenue. The district is regarded as an example of early suburban planning and of the Arts and Crafts ideals applied to residential design.","period_of_significance":"1912-1948","architect_builder":"Richardson, Harry; Conver, S.
