It has a castle-like \"medieval Spanish\" design, fine brick and terra cotta on the side elevations as well as the front, and an unusual decorative vocabulary. It is presented as a monument to the eclectic architecture of the 1920s.","narrative":"Malden Towers is a six-story apartment building with a large rooftop penthouse at 4521 North Malden Street in Chicago's Uptown. Built in 1928-29 to designs by Norwegian-born engineer N. T. Ronneberg, it is a common-corridor building, a type that packed small apartments along a central hallway on a narrow city lot. Its light tan pressed brick and cream terra cotta walls carry polygonal turrets, battlemented parapets and polychrome ornament of swords, shields, fasces and floral motifs, giving a medieval Spanish flavor. Unlike most similar buildings, it uses fine brick and terra cotta on the side walls too, leaving common brick only at the rear. The facade was narrowed to two-thirds of the lot width to stress its height. Of 77 comparable Uptown buildings, it is described as the most distinctive. It was well rented through the Depression and reportedly housed celebrities. Some original elements, including the entrance doors, roof tiles on the turrets and some gables, have been lost.","period_of_significance":"1900- (specific dates 1928-29)","architect_builder":"N.
