The 155 Harbor Condominium is an International Style skyscraper designed by Solomon Cordwell Buenz and built between 1972 and 1975 in Chicago, IL.

155 Harbor Condominium is not the only name you might know this building by though. The building is, or has also been known as Harbor Point.

Its precise street address is 155 North Harbor Drive, Chicago, IL. You can also find it on the map here.

Together with the Lake Point Tower, which was completed in 1968 just a few blocks away, the Harbor Condominium is another example of the possibilities of curved curtain walls. This goes back to some of the exploratory exercises that Mies van der Rohe, a big influence in the adoption of this type of facade, had been playing with back in 1922 in Berlin.

Architect and team

Solomon Cordwell Buenz was the architecture firm in charge of the architectural design.

Architectural Style

The 155 Harbor Condominium can be categorized as an International Style building.

The international style originated in Europe in the early 20th century, and made its way to the US a couple of decades later when the rise of the Nazi regime forced figures such as Walter Gropius, Marcel Breuer, or Mies van der Rohe to flee Europe.

The International Style emerged as a response to the prevailing historicism and ornate architecture styles of the late 19th century, which according to a younger generation of architects didn't represent the new materials and construction techniques that were on the rise at the time.

Architecture in the early 20th century US was marked by the adoption of steel structures, modern construction techniques, and the rise of the skyscraper. As it turns out, this combination of circumstances created the perfect ecosystem for the International Style to flourish, becoming the to-go style for skyscraper designs during the mid-20th century, when American cities were growing fast.

The International Style’s legacy can not only be found in numerous iconic buildings across all major American cities, but also incorporated in contemporary architecture, which still puts a big emphasis on functionality and minimalism.

Materials & Structure

The 155 Harbor Condominium uses a frame structure made of concrete columns and beams.

A frame structure uses a combination of beams and columns to sustain the building's weight. The walls in this case are non-load bearing, which allows for more flexibility when distributing the interior spaces.

The facade is non-load bearing either, as it is common in frame structure type buildings.

From an aesthetic point of view, the facade features metallic black spandrels between rows of dark gray mirrored glass. The curved curtain wall, raises on columns at the ground level, which allows the lobby to take a step inwards, creating a covered, yet open transitional space between the outside and the inside.

Other materials found at the 155 Harbor Condominium include, rose granite, used on the lobby's floors, beige stone, found in large panels covering the lobby's walls, and wood, seen in some details of the lobby, such as the concierge desk, residents' mailboxes, or the staircase railing.
