The Hellman building was constructed in 1902 By Alfred Rosenheim on the site of Herman W. Hellman's one story cottage. It was developed by one of California's leading financiers, Isaias Hellman, the brother of Herman Hellman. The Hellman building is a six story structure with green terra cotta and classical décor located in the heart of Downtown Los Angeles near 4th and Main streets. It is a stylistic and representative example of commercial architecture in the early 20th century with its brick and concrete structure, steel skeleton frame, stained glass and marble found in its interior. The building was designed using a steel frame construction for architectural quality and integrity instead of concrete. When it was built it was the largest steel frame building in Los Angeles.
