Transamerica Pyramid, Embarcadero Center and Financial District

Transamerica Pyramid

The Transamerica Pyramid is the second tallest building in San Francisco and one of the most recognizable high-rise buildings in the world.

The 6,000-watt beacon at the buildings peak, envisioned by the architect as the building’s “crown jewel,” can be seen from all over the San Francisco Bay Area at night when lit on special occasions.

At 853 feet high (260 meters), the Transamerica Pyramid remains one of the tallest buildings in San Francisco. The 48-floor high-rise building is constructed of concrete, glass and steel — and capped with a decorative aluminum 212-foot spire (64.6 meters) rising above the top floor and the “crown jewel” of the building, the beacon at the top.

The 48th Floor serves as an impressive conference room boasting stunning, unobstructed 360-degree views of San Francisco Bay.

The Transamerica Pyramid has 500,000 total square feet of floor space. Its distinctive pyramid shape allows for varied floor plates ranging from the 6th floor, with 22,226 square feet, to the 48th floor, with just 2,531 square feet.

The 9-foot-deep concrete mat foundation, which was continuously poured over a 24-hour period with 1,750 truckloads of concrete, rests on a steel and concrete block, sunk 52 feet (15.5 meters) into the ground, and is designed to move with earth tremors. The Pyramid’s base and foundation is constructed of approximately 16,000 cubic yards of concrete, encasing more than 300 miles of steel reinforcing rods.

FAQ: Why was the Transamerica Pyramid built in the shape of a pyramid? 

In addition to being a stylistic statement, the Transamerica Pyramid’s unconventional silhouette is also the result of environmentally sensitive planning. The tapered design casts a smaller shadow and therefore allows more natural light to filter down to the streets below than its conventional high-rise neighbors — important in a city where the sun has to do almost daily battle with the fog.

In designing the building, architects William Pereira & Associates also were adhering to San Francisco’s unique shadow restriction legislation, which impose a certain ratio between buildings’ surfaces and their heights.
