601 California Street

601 California Street is an office tower in San Francisco's Financial District with 22 floors designed in the International Style. The building features corner offices on each level and includes landscaped outdoor spaces on select upper floors.

Completed in 1961 by architects Anshen & Allen, the building won recognition from the American Institute of Architects in 1963. It marks a turning point when San Francisco's financial district embraced a new approach to office design.

The building's design reflects how San Francisco transformed its downtown into a center for modern office work during the 1960s. Its clean lines and efficient layout represent the business values of that era.

The location in the North Financial District provides easy access to public transportation and is within walking distance of shops and restaurants. Keep in mind that this is an active office building, so interior access may be limited to lobby areas.

The building includes landscaped terraces on both the fourth floor and at the top on the twenty-second level, which was unusual for office buildings of that era. These outdoor spaces provided rare amenity at elevation during a time when such features were rarely planned into commercial towers.
