One America Plaza

One America Plaza is an office building in downtown San Diego with 34 floors and a height of about 152 meters. The structure features an angular obelisk shape with a pointed top and is built with extensive glass and steel elements.

This building was completed in 1991 and was San Diego's tallest structure at that time. It was designed by German-American architect Helmut Jahn, who created an innovative design for the city.

The building represents late 20th-century modernist architectural principles through its angular geometry and extensive use of glass and steel materials.

The building sits directly next to the America Plaza trolley station, making it easy to reach by public transportation. The entrance area is at ground level and easy to access for visitors.

The building's top resembles the head of a Phillips screwdriver, a design feature the architect reused in other projects. This unusual shape makes the structure particularly recognizable from different angles around the city.
