Brown Marx Building
The Brown Marx Building (or Brown Marx Tower) is a 193,000 square foot, 16-story, 210 foot tall Chicago-style steel-frame office tower on the northeast corner of 20th Street and 1st Avenue North. From its completion in 1906, until it was eclipsed by the Empire Building three years later, it was the tallest structure in Birmingham.
The Brown Marx Building was named for Otto Marx of Marx & Company and Eugene L. Brown of Brown Brothers, early tenants of the structure. (The alternate name, The Eugeneotto Building, was rejected early-on). It was built in two phases beginning with a narrow 16-story tower on the corner (pictured), which was completed in 1906. The immediate success of that building encouraged the builder to more than double the overall size of the building over the next two years. In 1908 the footprint of the building was expanded, creating a U-shaped plan with an average of about 12,000 square feet per floor and windows providing natural light to every office.
The building was financed by the Tennessee Coal Iron and Railroad Company, and designed by architect William Weston. The exterior of the building was light-colored brick with rusticated banding and arched windows on the third story, surmounted by a cornice. The ground floor was clad in stone with broad expanses of glass showcasing retail goods. The interior was clad in Alabama marble, and the roof parapet was surrounded by a broad, highly detailed cornice. Most of these details have since been removed. As early as 1930, when the building was again expanded, the rusticated story was covered over with a more "streamlined" art-deco inspired light-colored banding. The cornice has since been replaced by a metal-clad mechanical enclosure at the roofline.
The four early Twentieth century skyscrapers at 20th Street and 1st Avenue were billed, at the time, as the "Heaviest Corner in the South." Over the years, that claim was inflated to the improbable "Heaviest Corner on Earth", which remains a popular name for the grouping. In 1985 the "Heaviest Corner on Earth" was added to the National Register of Historic Places.
In 1951 U. S. Steel (which had absorbed TCI) moved their Birmingham headquarters from the Brown Marx to the new Flintridge Building in Fairfield. A pool hall was located in the basement for a while. Other tenants included the Southern Building Code Congress.

 Recent plans
In 2002, Inman Park Properties purchased the Brown Marx Building along with the Empire Building across 20th Street and the Commerce Center at 1st Avenue North and 21st Street. The following year they proposed to convert the Brown Marx into over 100 loft apartments, perhaps in tandem with the Empire Building. In advance of the planned renovation they moved most of Brown Marx's tenants to the Commerce Center. Unable to negotiate a deal with the Birmingham Parking Authority to build a new deck adjacent to the site, they abandoned the renovation.
In 2006 SAW Holdings LLC, a group of local investors led by former Pride Restaurants owner Arnold Whitmore announced places for a $22 million renovation of the building, including 108 condominiums, a roof-top pool, gym, spa, a top-floor bar, an executive office suite, and ground floor restaurant, office and retail space. The proposal included a 200-space parking deck to be built adjacent to the tower. RealtySouth and Nationwide were jointly marketing the condominiums and opened sales office in the building.
Falling glass from upper-story windows caused the Birmingham Department of Planning, Engineering & Permits to require the owner to protect the sidewalks with covered walkways which were installed in September, 2006. In 2009 part of the metal facade came loose during a strong windstorm. The city entered into an emergency contract to remove the metal in the interest of public safety.
In March 2012, National Bank of Commerce sold the building to Hughes Capital Partners LLC, which planned to redevelop a portion of the building for its own offices and was exploring options for the rest of the space.
