Merithew. It was built in Los Angeles and moved to its current site in 1982.","why_significant":"The house is locally significant under Criterion C as a rare, high-style example of Queen Anne residential architecture. It keeps an extraordinary amount of its ornamentation, wall materials, windows and roof forms. It is also an important work of regional architect William O. Merithew.","narrative":"Built in 1893 to designs by architect William O. Merithew, this two-and-a-half story wood house is an elaborate example of Queen Anne architecture. It first stood near downtown Los Angeles, was moved in 1902 to West 30th Street near the University of Southern California, and was moved again in 1982 to Locke Haven Street in Pasadena. Its exterior combines clapboards, sunken panels, patterned shingles and carved friezes, with an irregular plan, steep intersecting roofs, a small belvedere, and an ornate entry porch with a keyhole-arched screen. Some art glass transoms, porch elements and the foundation have been replaced, and a rear addition and a garage/studio date from the early 1980s. The house was listed for its architecture under Criterion C. It is considered a rare and notable local example of high-style Queen Anne design that retains most of its ornament, and its mature setting and neighborhood scale suit its historic character despite the moves.","period_of_significance":"1893","architect_builder":"Merithew, William O.
