Sitting unapologetically atop a 9 level parking garage podium to bring it level with adjacent Bunker Hill and Hope Street, the 55 story Bank of America Plaza sits as a monument to all that went wrong with the planning of downtown Los Angeles. The podium (which has lovely gardens on top), absolutely destroyed the streetscape on the Flower Street, 3rd Street and 4th Street sides of the tower, creating the need for oddly sloped pedestrian bridges to adjacent (and yet raised) buildings. The result is a pleasant, but extremely isolated space, hugely disconnected from the rest of downtown. This is not unlike several other buildings on Bunker Hill, this one just happened to be the first office tower and one of the largest overall.
The tower is unique only in that it sits at a 45 degree angle to the street grid, with chamfered corners and a granite clad cap. 70's modernism at its finest! The complex was designed by AC Martin & Partners and is arguably their least appealing project in downtown LA. Originally the headquarters for Security Pacific Bancorp, the tower has had a number of logos on its crown since SPB was acquired by BofA in 1991: Arco, BP and lastly Bank of America (who moved their main LA offices from the BofA/Arco Plaza on Flower Street in the early 00's).
When completed in 1974, this was the 2nd tallest building in the city. It's still 5th.
