Gas Company Tower vs Westin Bonaventure Hotel

Gas Company Tower
Westin Bonaventure Hotel

Comparing the Gas Company Tower and the Westin Bonaventure Hotel is interesting because they both rise in Los Angeles, CA, yet they were conceived by two different design teams, Skidmore, Owings & Merrill and John C. Portman Jr., and were completed at different points in time. They were finished more than a decade apart.

This contrast within the same city allows us to see how different creative minds interpreted the evolving needs of Los Angeles across time.

Structure & Facade

Structure

Facade
Curtain Wall

Both the Gas Company Tower and the Westin Bonaventure Hotel rely on a Frame structural 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.

They also employ the same type of facade, a Curtain Wall facade.

A curtain wall is a non-load-bearing facade hung from the structural frame. It is anchored to floor slabs and transfers only its own weight and wind loads, allowing for sleek, glassy exteriors.
