The Pacific Electric Building (also known as the Huntington Building, after the developer, Henry Huntington, or 6th Main for its location) opened in 1905 as the terminal for the Pacific Electric Red Car Lines running east and south of downtown Los Angeles, as well as the company`s main headquarters building. It was designed by architect Thornton Fitzhugh. Though not the first modern building in Los Angeles, nor the tallest, its large footprint and ten floor height made it the largest building in floor area west of Chicago for several decades after its completion. Above the main floor terminal were five floors of offices and, on the top three floors, the facilities of the Jonathan Club, one of the city`s leading businessmen`s clubs. The club moved to its own building on Figueroa Street in 1925.
