The main building was designed in 1893 and the annex in 1896 by Patton & Fisher.","why_significant":"The nomination presents it as a fine, rare surviving late 19th-century tall apartment building in Chicago, combining Chicago School form with Queen Anne and Richardsonian Romanesque detailing. It is also a good example of multi-family residential work by Patton & Fisher, a firm better known for municipal buildings. It is the tallest building in the Grand Boulevard area and reflects the area's development around transit and the 1893 World's Columbian Exposition.","narrative":"Belmonte Flats is an eight-story apartment building on the northeast corner of 43rd Street and Dr. Martin Luther King Jr. Drive in Chicago's Grand Boulevard community area. Patton & Fisher designed the main block in 1893 and a four-story annex in 1896; an enclosed brick walkway links the two at the third and fourth floors. The building has a battered limestone base, brick upper stories, curved oriel windows, a cylindrical corner tower and a foliated terra cotta cornice. Its style is mainly Chicago School, with Richardsonian Romanesque massing and Queen Anne rounded bays. Inside, the lobby keeps its ornamental ceiling beams and some mosaic tile flooring. It was listed as one of few remaining late 19th-century tall apartment buildings in Chicago and as a rare multi-family design by a firm known for municipal work. It has been vacant for years, a fire damaged the top floor, and a rehabilitation was planned.","period_of_significance":null,"architect_builder":"Patton & Fisher","architectural_style":"Chicago School with Queen Anne and Richardsonian Romanesque detailing","criteria":[],"status_note":"Vacant for years; a fire damaged the eighth-floor roof.
