In 1953, forty years after the original Central Fire Station opened, a new addition was constructed on the north side.  It was designed by K. E. N. Cole Jr. during the administration of Little Rock Mayor Pratt Remmel and Fire Chief Gann Nalley.  This structure was used for additional offices and storage.

It is fairly representative of mid-century government architecture.  With a flat roof and clean lines, it uses buff brick (which more closely matches the 1936 garage and 1938 jail than the 1913 fire station). The building features corrugated metal used as a decorative accent.  It does not appear there was any attempt to try to seamlessly blend in with the original building.

As part of the mid 1980s renovation, new windows were installed in this structure, but the original window style remains.  Today the building houses various City offices.
