One Atlantic Center vs One International Place Building

Comparing the One Atlantic Center and the One International Place Building is an interesting exercise, because even though they are located in different cities (Atlanta, GA and Boston, MA), both were designed by Johnson/Burgee Architects and finished within in the same year. This gives us the chance to see how the same architect's ideas were expressed in different urban contexts almost simultaneously.

The One Atlantic Center is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 820ft (250m) with 50 floors above ground, while the One International Place Building reaches 600ft (183m) with 46 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 Atlantic Center and the One International 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 Johnson/Burgee Architects followed what was in many ways expected at the time, producing designs that fit comfortably within contemporary architectural norms rather, than breaking with convention.

Both the One Atlantic Center and the One International 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 Atlantic Center offering 2200 spaces and the One International Place Building offering 400.

The two buildings opted for different structural and facade solutions.

The One Atlantic Center uses a Framed Tube In Tube system, which combines a strong central core with a perimeter tube of columns, while the One International Place Building uses a Frame system, that relies on a regular grid of columns and beams to sustain its weight.

And when it came to the facade, the Curtain Wall went with a Curtain Wall facade, which uses a lightweight glass curtain wall hung from the structure, while the One International Place Building opted for a Window Wall facade, that uses panels fitted between floor slabs, leaving slab edges visible.
