Willoughby-Suydam Historic District

Why it's listed
Fifty three-story brick tenements, built between 1904 and 1906, make up this four-acre district in the Brooklyn part of Ridgewood. The rows line Willoughby Avenue, Suydam Street, Wyckoff Avenue and St. Nicholas Avenue, and each floor holds two apartments. They stand apart from the large industrial buildings and altered frame houses nearby. Robert T. Rasmussen designed and built the rows on Willoughby, Suydam and Wyckoff, which feature yellow and white terra-cotta ornament such as Greek fret bands and wreath-and-ribbon lintels. Louis Berger designed the St. Nicholas Avenue rows, built by Jacob Blank in 1904, with brownstone trim in the Romanesque Revival style. Because the area lay in Brooklyn, an earlier fire code required masonry, giving the district some of the earliest all-brick rows in Ridgewood. The narrow, dark apartments reflect tenement design before the Mathews Model Flat. Some buildings are vacant and deteriorating, while most of the district remains stable.
Significance in brief: The district is an intact grouping that reflects the earliest phase of working-class tenement housing in Ridgewood. Because it lies entirely in Brooklyn, it was subject to the earlier fire code requiring masonry, so it contains some of the earliest all-brick rows in the area. The buildings show applied stone and terra-cotta ornament in Romanesque, Renaissance and Classical Revival styles, with rows by builder Robert T. Rasmussen and architect Louis Berger.

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).
