It also contains distinctive examples of a range of period architectural styles, including late Queen Anne, Shingle, Colonial Revival and Mission. The surrounding area has been heavily altered, while the district keeps its scale and character.","narrative":"Halcyon Place is a short cul-de-sac in Yonkers, New York, running up a slope east of Warburton Avenue. Its 12 primary houses, built between 1900 and 1924, form a planned suburb laid out by Harry Woodhouse, a local carpenter and builder who bought the Sawyer estate in 1900 and deeded the new street to the city in January 1901. The modest frame and masonry homes were built for middle-class buyers seeking to leave the crowded, industrialized city center. Most are two or two-and-a-half stories and show late Queen Anne, Shingle, Neoclassical, Colonial Revival and Mission styles, with similar massing, setbacks and lot sizes giving the street a unified look. Some houses have had siding changes, storm windows or porch alterations, but the street keeps the character of an early twentieth century neighborhood. The district was listed for its architecture and for its role in the community development of Yonkers as it became a suburban community, in contrast to the altered surroundings.","period_of_significance":"1900-1924","architect_builder":"Harry Woodhouse (developer/builder); architects named for individual houses include George S.
