Structures / Transamerica Pyramid

• Chin & Hensolt

• Walter Hensolt

Despite initial critical response to its architectural form when it first opened, the Transmerica Pyramid building has become the signature building on the San Francisco skyline with its distinct features and has only recently been eclipsed as the tallest building in San Francisco.

The Transamerica Pyramid building is a steel moment frame structure. It is 48 stories and stands 853 feet tall. At the time of completion, the Transamerica Pyramid was the eighth tallest building in the world and was the tallest skyscraper west of Chicago until 1974. The two “wings” on the tower are the elevator shafts leading to the top levels.
