It is described as the only house of its type, with cubic masses and slab roofs, still standing in Chicago. It is also cited as evidence of the success of German immigrants in Chicago.","narrative":"Located at 7415 North Sheridan Road in Chicago, this two-story house with a basement was designed by Frank Lloyd Wright for Emil Bach in 1915. Bach was one of five brother shareholders in the family brick company, which his German immigrant father had started as a pottery after the family arrived in 1883. The house belongs to a series of geometric cubic designs with overhanging flat roofs that Wright produced after returning from Europe in 1911. Its first floor is a compact square, while cantilevered bay windows on the upper floor open up the walls and shade the level below. The narrow stairwell uses little space yet draws in plenty of light. Later owners enclosed the rear porch and sundeck with glass, in a manner described as sympathetic to Wright's intent. The house was listed because it is a late Prairie School work at a point of stylistic change and the only surviving example of its type in Chicago.","period_of_significance":"1900- (specific date 1915)","architect_builder":"Frank Lloyd Wright","architectural_style":"Late Prairie School","criteria":[],"status_note":"Described as occupied and in use as a single-family private residence.
