Ridgewood is a densely settled neighborhood, with housing stock ranging from six-family buildings near the Brooklyn border to two-family and single-family row houses deeper into Queens. Ridgewood is visually distinguished from Bushwick by the large amount of exposed brick construction; in Brooklyn, vinyl siding is more common. Like neighboring Bushwick, nearly all of the buildings in Ridgewood are classified as combustible.
Most of Ridgewood was developed block-by-block around the turn of the 20th century. Most of the buildings were designed by local architect Louis Berger & Co., which designed more than 5,000 buildings in the area. The neighborhood has been largely untouched by construction since then, leaving many centrally planned blocks of houses and tenements still in the same state as their construction. These blocks include the Mathews Flats (six-family cold water tenements), Ring-Gibson Houses (two- and four-family houses with stores), and Stier Houses (curved two-family rowhouses). Many of these houses are well-kept and retain much of their early 20th century appeal.
