Turtle Bay Gardens Historic District
Why it's listed
Turtle Bay Gardens is a tranquil enclave of twenty row houses on East 48th and East 49th Streets in midtown Manhattan. The four-story Italianate brownstones were built by a speculative builder in the 1860s. After Mrs. Walton Martin bought them in 1919, architect Clarence Dean removed the stoops, added rusticated English basements, installed uniform casement windows and covered the spalling brownstone with tinted stucco. Each house gave up six feet of its rear lot to form a shared garden with a flagstone walk and a fountain based on a Roman prototype at the Villa Medici. An old willow there appears in E.B. White's 1949 book Here is New York. The district matters as a 1920s planned community drawing on English terrace house and garden suburb ideas. Residents also adopted covenants limiting height, additions, materials and building use. Well-known theatrical and literary figures have lived here, drawn by the privacy the enclave offers.
Significance in brief: The district is presented as an intact 1920s planned community inside a large city, modeled on English terrace house schemes and garden suburbs. It is noted for the uniform scale, stucco facades and shared courtyard designed by architect Clarence Dean, and for early protective covenants agreed by residents. It is also associated with theatrical and literary residents.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
