Sunnyside Gardens, in the Sunnyside neighborhood of the New York City borough of Queens, was one of the first developments to incorporate the "superblock" model in the United States. The residential area has brick row houses of two and a half stories, with front and rear gardens and a landscaped central court shared by all. This model allowed for denser residential development, while also providing ample open/green-space amenities. Clarence Stein and Henry Wright served as the architects and planners for this development, and the landscape architect was Marjorie Sewell Cautley. These well-planned garden homes are listed as a historical district in the National Register of Historic Places, and are also home to one of two private parks in New York City, the other being Gramercy Park.
