One International Place Building vs Exchange Place Building

Comparing the One International Place Building and the Exchange Place Building is interesting because they both stand in Boston, MA, and were completed within 3 years of each other, but they were designed by different architects.

This offers a unique glimpse at how rival designers approached projects in the same city during the same era.

The One International Place Building is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 600ft (183m) with 46 floors above ground, while the Exchange Place Building reaches 509ft (155m) with 40 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.

Both the One International Place Building and the Exchange Place Building were designed in line with the aesthetic conventions of the Postmodernism style.

At the time, this style was at the height of its popularity. So both Johnson/Burgee Architects and WZMH Architects followed what was in many ways expected of them, producing designs that fit comfortably within contemporary architectural norms, rather than breaking with convention.

Both the One International Place Building and the Exchange Place Building were designed to serve as commercial towers, and that has remained their main use since their completion, serving similar roles in the urban fabric.

Both towers provide significant parking capacity, with One International Place Building offering 400 spaces and the Exchange Place Building offering 126.

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 International Place Building uses a Window Wall facade, while the Exchange Place Building uses a Curtain Wall facade.

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