There is an observation deck on the 50th floor giving a birds eye view of the city of Johannesburg.

Carlton Centre was sold in 1999 for R33 million (US$3.3 million) and now houses the head office of Transnet, the South African Transport parastatal.

The centre has the largest city parking arcade in South Africa.

Carlton Centre was the tallest building in the southern hemisphere when completed and is still the tallest building in Africa.

The buildings have a reinforced concrete structure with an exposed exterior aggregate and an integral finish of local gray granite exposed by sand blasting.

The tower has spandrel beams supporting ribbed slabs at each floor level.

The foundations of the two buildings in the complex are 3.5m in diameter and extend 20m down to the bedrock, 30m below street level.

The tower has a slip formed reinforced concrete core and perimeter columns tapering from three square meters at street level to one square meter at the top floors.

The Carlton Centre is linked to the Carlton Hotel by a below ground shopping centre with over 180 shops as well as an ice skating rink all set below an above ground public plaza.
