The 2121 Building is a 17-story, 276-foot-tall high rise office building located at 2121 8th Avenue North in Downtown Birmingham. It was developed, in 1962–63 by Cobbs, Allen & Hall for the Bloomefield-Sender Enterprise of Memphis, Tennessee. The development was leased primarily for federal offices. Original tenants included the Internal Revenue Service's Alabama district office.
The 227,447 square-foot concrete-framed building was designed by John H. Summer and Associates of Atlanta, Georgia and cost $2.5 million to construct. It occupies a 200-foot x 190-foot L-shaped tract on the south side of 8th Avenue between Richard Arrington, Jr Blvd North and 22nd Street North.
WAQY-AM operated a penthouse studio from the 2121 Building beginning in the late 1960s.
In 2006 the building's interior underwent significant renovations. Alagasco designed and installed a 3-unit hybrid boiler system to replace the building's original boiler. Because the multi-jurisdictional Personnel Board of Jefferson County is the primary tenant, the various municipalities who participate in the employment system were asked to contribute to the cost of renovations.
