It was built between 1899 and 1902.","why_significant":"The district is a distinctive enclave of French Beaux-Arts residences with an unusual degree of stylistic unity. Restrictive covenants governing design, height and setbacks gave the turn-of-the-century houses an open, Paris-like scale. Its architect-designed row houses, with varied ornament, form some of the most impressive blocks on the Upper West Side.","narrative":"Thirty buildings make up this L-shaped enclave on Manhattan's Upper West Side, running along West 105th Street, Riverside Drive and part of West 106th Street. The land sits high above Riverside Park and the Hudson River. All of it was developed between 1899 and 1902 as a neighborhood of single-family row houses and mansions, mostly of light limestone, with some brick trimmed in limestone. French Beaux-Arts design dominates, and restrictive covenants controlled the houses' design, height and setbacks, giving the streets an open, Parisian scale. Cornices, wrought-iron balconies and mansard roofs create strong horizontal lines on 105th Street, while bowed fronts set a gentle rhythm as the street slopes toward the drive. The houses have since been converted to multiple dwellings or institutions, yet their architectural character remains intact. The only intrusion is a Buddhist church built in 1963 at 332 Riverside Drive. The district was listed for its cohesive, architect-designed streetscape, which is among the most impressive on the Upper West Side.","period_of_significance":"1899-1902","architect_builder":null,"architectural_style":"French Beaux-Arts","criteria":[],"status_note":"Originally single-family row houses and mansions, all now converted to multiple dwellings or institutions, with architectural integrity maintained.
