It was originally addressed as 490 Belden.","why_significant":"The nomination calls it the earliest remaining detached residence by Dankmar Adler and Louis Sullivan. It survives without important alterations and records the transition from period styles to Sullivan's early modern aesthetic. Its formal plan reflects Sullivan's academic training, while its massing and details follow the Queen Anne style.","narrative":"This brick house at 440 Belden in Chicago was designed in the spring of 1883 by Louis Sullivan, then in partnership with Dankmar Adler. The blueprints carry the label \"D. Adler & Co.\" and the cost was reported as $15,000. Ann Halsted lived there by May 1884. The design mixes styles. Pointed bay windows and corbelled brick cornices and chimneys reflect Queen Anne taste, while the strictly formal front and the simplified facade point to Sullivan's French training. Sullivan's own ornament appears in the front and rear dormers, the rounded pediments on the sides, and the parlor fireplace. Inside are oak and cherry woodwork, stained-glass windows and period fireplaces. It is the earliest surviving detached residence by Adler and Sullivan and has no important alterations. The house shows Sullivan's architecture growing out of contemporary historic styles toward a modern approach.","period_of_significance":"1883-84","architect_builder":"Louis Sullivan; Dankmar Adler (drawings labeled \"D.
