One Beacon Street Building vs Trump International Hotel and Tower

Comparing the One Beacon Street Building and the Trump International Hotel and Tower is compelling because they were both designed by Skidmore, Owings & Merrill, yet they stand in different cities (Boston, MA and Chicago, IL), and were completed over two decades apart.

What this will allow us to see, is how the same firm's approach adapted to different places in different periods of time.

The Trump International Hotel and Tower is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 1181ft (360m) with 92 floors above ground, while the One Beacon Street Building reaches 505ft (154m) with 36 floors above ground.

Of course, each project may have faced different briefs or regulatory constraints, which we don't really know about and could also explain the outcome.

The One Beacon Street Building was designed in the International Style style, while the Trump International Hotel and Tower reflects the principles of Contemporary.

The One Beacon Street Building represents a late expression of the International Style, a style already in decline in 1972 when it was completed. By contrast, the Trump International Hotel and Tower followed the then mainstream Contemporary, embodying the dominant architectural direction of its time.

With 37 years between them, the comparison also reflects how quickly architectural priorities can shift from one dominant language to another.

The Trump International Hotel and Tower follows a mixed-use model, combining hotel, residential and commercial. In contrast, the One Beacon Street Building has remained primarily commercial.

The Trump International Hotel and Tower incorporates a 5-star hotel with 339 rooms. More information is available at the official website.

The Trump International Hotel and Tower offers 486 residential units.

The Trump International Hotel and Tower also provides 960 parking spaces.

Both towers share the same structural solution, a Frame system.

A frame structure uses a grid of columns and beams to carry the building's loads. This frees the walls from structural duties, allowing for flexible floor plans and larger windows.

However, when it comes to the facade, both buildings use different approaches. The One Beacon Street Building uses a Window Wall facade, while the Trump International Hotel and Tower uses a Curtain Wall facade.

A Window Wall facade like the one seen in the One Beacon Street Building uses panels fitted between floor slabs, leaving slab edges visible, while a curtain-wall facade like the one seen in the Trump International Hotel and Tower uses a lightweight glass curtain wall hung from the structure.
