Nyden.","why_significant":"The nomination cites the building's geometric simplicity within the Prairie School style. Limestone banding and wooden window mullions create linear patterns that reinforce its rectilinear massing, while unusual courtyard doorways contrast with the strict geometry. It also represents the Prairie phase of architect John Nyden's work applied to a courtyard apartment.","narrative":"Built in 1912 at the northwest corner of Hinman Avenue and Keeney Street in Evanston, this Prairie School courtyard building rises three stories above an English basement. Architect John A. Nyden used red brick with limestone trim, a hipped roof and a bracketed cornice. Limestone bands at the first- and third-floor sill lines emphasize the horizontal profile. Five courtyard doorways stand out, each topped with a projecting limestone segmental arch carrying geometric detail. The building holds thirty apartments, twenty-four with one bedroom and six with three bedrooms, and all have sun porches and wood-burning fireplaces. Its significance rests on the geometric simplicity of its design within the Prairie School style. Limestone banding and wooden window mullions form linear patterns that reinforce the rectilinear massing, and the unusual doorways act as a counterpoint to that strict geometry. Nyden designed many Evanston apartment buildings, and this one represents the Prairie phase of his work applied to a courtyard plan. He later served as State Architect in 1927.","period_of_significance":null,"architect_builder":"John A.
