The Solow Building is a Modern Style skyscraper designed by Skidmore, Owings & Merrill, with Gordon Bunshaft as lead architect, and built between 1968 and 1974 in New York, NY.

Solow Building is not the only name you might know this building by though. The building is, or has also been known as 9 West 57th Street.

Its precise street address is 9 West 57th Street, New York, NY. You can also find it on the map here.

The building has been restored 2 times over the years to ensure its conservation and adaptation to the pass of time. The main restoration works happened in 2024 and 2000.

  1. 2024 - A comprehensive renovation was carried out inside the building, updating the lobby lighting and incorporating artwork. A new lobby was opened, leading to the lower level where a gym was installed. Meeting rooms and a cafes were added, complemented by a public gathering space in the outdoor plaza, now renovated with new trees and seating. The architect in charge was Skidmore, Owings & Merrill.
  2. 2000 - The unused basement space was redesigned to accommodate a restaurant. Two escalators were removed to create an entrance to the new venue. The architect in charge was Hardy Holzman Pfeiffer.

Architect and team

Skidmore, Owings & Merrill, with Gordon Bunshaft as the lead architect, was the architecture firm in charge of the architectural design.

Commonly known as SOM, the firm was founded in Chicago in 1936 and has grown to be one of the largest architecture firms in the world.

Even long after its founders passed away, SOM has remained at the top of worldwide architectural excellence by attracting visionary architects. Amongst their most notorious partners we find names such as Gordon Bunshaft, Bruce Graham, Walter Netsch, Adrian Smith, Myron Goldsmith or David Childs.

SOM has also managed to grow and evolve to tackle the architectural challenges of each time, whatever those might be, and today is committed to aspects as important as efficiency and sustainability, as core values of their designs.

With a legacy spanning decades, SOM continues to shape the skylines of cities around the world, and is a usual contestant in any competition or selection process to design large-scale or iconic buildings and structures.

That being said, architecture is a complex discipline involving many professionals from different fields, without whom this building would have not been possible. We will surely be leaving out a lot of names here, but here is a list of the people we do know also played their part in making the Solow Building a reality:

  • Weidlinger Associates in charge of Structural Engineering
  • Solow Construction Co. as the Main Contractor
  • Solow Development Corporation as the Main Developer
  • Cosentini Associates in charge of MEP Engineering
  • Ivan Chermayeff as the collaborating Artist

Architectural Style

The Solow Building can be categorized as a Modern Style building.

The modern style, also referred to as Modernism in the U.S. (distinct from the European Modernist movement), is characterized by minimal ornamentation, clean lines, and the use of materials such as glass, steel, and concrete. This style prioritizes functionality and the honest expression of materials and structure.

Modern architecture in the U.S. follows many principles of the International Style but with slightly less rigid rules than those of the purist European International Stylists like Le Corbusier, or even those who imported the style to the U.S. like Mies van der Rohe and Walter Gropius.

Modern skyscrapers often feature expansive glass curtain walls, open floor plans, and focus on volume over mass. This blend of innovation and simplicity defined the modern skyscraper, creating the sleek, functional urban landscapes prominent in mid-20th-century U.S. architecture.

The Solow Building was completed in 1974. by then, Modernism had already past its maturity, and other styles, such as Postmodernism or Brutalism were already challenging its principles.

By their own nature, the Modern and International Styles can still look current, even in contemporary buildings. So that's not to say the Solow Building appeared old or outdated when it was completed, but Skidmore, Owings & Merrill certainly did not take many risks when it came to choosing the design style. This made the building look more "classic" and integrated within the city's architecture.

Spaces & Uses

The Solow Building reaches an architectural height of 673ft (205m). It has a total of 50 floors, 49 above ground and 1 basements, served by 34 elevators.

Ever since opening its doors to the public in 1974, the Solow Building has mainly been used as Commercial space.

Materials & Structure

The Solow Building uses a trussed-frame structure made of steel columns and concrete and steel slabs.

A trussed-frame structure uses a combination of beams and columns to sustain the building's weight, and diagonal elements to provide stability against horizontal forces such as wind or seismic activity by triangulating the structure. The walls in this case are non-load bearing, which allows for more flexibility when distributing the interior spaces.

The facade uses a non-load bearing curtain wall system. This means the curtain wall modules are anchored to the building's structural frame, typically by being attached to the edge of the floor slabs. The curtain wall system connects to the slabs using brackets, anchors, and mullions, which transfer the loads imposed by wind and temperature changes, to the building's primary structural elements.

This setup allows the curtain wall to accommodate differential movement between the facade and the structural frame, such as thermal expansion, floor deflection, or sway from wind forces. This system's integration with the slab edges also allows for continuous insulation and weatherproofing layers.

The tower is distinguished by its north and south elevations that gradually slope inward, from ground level to the 18th floor.

The building's exterior columns protrude from beneath the gutter at the same acceleration angle for both engineering and aesthetic reasons

From an aesthetic point of view, the facade features grey tinted glass framed by narrow travertine bands at the corners of the North and South facades, with a slightly thicker band at the top.

On the narrower East and West facades the travertine walls are wider, framing a narrow glass window where the X-shaped structural steel reinforcements protrude. The structural bracing on these facades uses black aluminum cladding.

At ground level, an open-air plaza with a travertine floor featuring a prominent red sculpture with the number 9 provides access to the building.
