Draper and Kramer, Incorporated, has started construction on 61 Banks Street, a new boutique residential rental building along Chicago’s lakefront. The intimate eight-story property, which will grace the last undeveloped site on North Lake Shore Drive in the Gold Coast neighborhood, will feature a mix of 58 upscale two- and three-bedroom residences, including seven two-story “maisonette” rowhome units with direct street-level entrances and private terraces.
