40 Marietta Street Office Building, Atlanta, Georgia

The HADP goal for the project was to explore the introduction of concrete structural technology to create a dynamic pioneering new building design that would set a distinctive mark on the sky line of Atlanta. The building was originally designed as the headquarters of a major regional saving and loan association. The Bank captured the iconic image of the building for use as its logo.  Likewise, the distinctive silhouette of the building has been a symbol of the growth of the city of Atlanta.

The innovative structural solution gave birth to the unconventional exterior of the 17-story building on Marietta Street. It is supported by six giant pentagonal columns, visible from the exterior of the building, with post-tensioned beams that ring each floor alternate with ribbon windows in grey-tinted glass. The elevator service tower toward the rear of the building is partly of poured-in-place concrete to stiffen the structure. The building has received many design awards over the years.
