Built in 1924, the 12-story Beaux-Arts building at 810 S. Spring Street was the headquarters of National City Bank of Los Angeles. With the important banks and financial institutions being concentrated there, the Spring Street Financial District was the financial center of Los Angeles in the first half of the 20th Century, known as Wall Street of the West. The building was designated a Historic Cultural Landmark (HCM #871) in 2007.

The building was converted from offices to 93 residential units in 2008. The building also has retail space.
