101 California Street Building vs One International Place Building

Comparing the 101 California Street Building and the One International Place Building is an interesting exercise, because even though they are located in different cities (San Francisco, CA and Boston, MA), both were designed by Johnson/Burgee Architects and finished within within 5 years of each other. This gives us the chance to see how the same architect's ideas were expressed in different urban contexts almost simultaneously.

Both the 101 California Street Building 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 101 California Street Building 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.

The One International Place Building also provides 400 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 101 California Street Building uses a Curtain Wall facade, while the One International Place Building uses a Window Wall facade.

A Curtain Wall facade like the one seen in the 101 California Street Building uses a lightweight glass curtain wall hung from the structure, while a window-wall facade like the one seen in the One International Place Building uses panels fitted between floor slabs, leaving slab edges visible.
