The Carlton Centre is a skyscraper and shopping centre located in downtown Johannesburg, South Africa. At 223 metres (732 ft), it has been the tallest office building in Africa since 1973. The Carlton Centre has 50 floors. The foundations of the two buildings in the complex are 5 m (16 ft) in diameter and extend 15 m (49 ft) down to the bedrock, 35 m (115 ft) below street level. The building houses both offices and shops, and has over 46 per cent of the floor area below ground level. The Carlton Centre is linked to the Carlton Hotel by a below-ground shopping centre with over 180 shops.
The Carlton Centre was designed by the American architectural firm Skidmore, Owings and Merrill. Anglo American Properties began construction in the late 1960s by demolishing the old Carlton Hotel and the closing roads to form a city super block. Excavations for the Carlton began in January 1967, and took two years to complete. Although occupation of the Centre began in 1971, construction was not finally completed until 1974. The building officially opened in 1973 at a total cost of over USD 6.55 million.
