Promontory Apartments

Why it's listed
Rising 22 stories above the Chicago lakefront at 5530-5532 South Shore Drive, this cooperative apartment tower was completed in 1949 to designs by Ludwig Mies van der Rohe. Its plan is a double T, with two linked buildings holding 122 units and avoiding long corridors. The reinforced concrete frame is left exposed and filled with buff brick and aluminum-framed windows. Columns on the east and west faces step back in four tiers, and the building is divided into a recessed ground-floor loggia, a shaft of residential floors, and a top element of two penthouses joined by a glass solarium. It was Mies's first high-rise and the first International Style high-rise apartment building in the United States. Developer Herbert Greenwald persuaded skeptical mortgage bankers to finance it, which opened the way for 860-880 Lake Shore Drive and later projects. The building remains a tenant-owned residence, with lobby and exterior restoration work carried out in the 1990s.
Significance in brief: The nomination argues it is nationally significant as the work of a master and for its high artistic value. It was Mies's first high-rise and the first International Style high-rise apartment building in the nation. It first realized two themes of his later work: an exposed structural frame and a tripartite horizontal division.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved.
