The city is often described as Africa’s economic powerhouse, and contentiously as a modern and prosperous African city. Johannesburg, like many metropolises, has more than one central business district (CBD), including, but not limited to, Sandton, Rosebank and Roodepoort in addition to the original CBD. Some tend to include Benoni and Germiston as well.

Due to its many different central districts, Johannesburg would fall under the multiple nuclei model in human geography terms. It is the hub of South Africa’s commercial, financial, industrial, and mining undertakings. Johannesburg is part of a larger urban region. It is closely linked with several other satellite towns. Randburg and Sandton form part of the northern area. The east and west ridges spread out from central Johannesburg. The Central Business District covers an area of 6 square kilometres (2 sq mi). It consists of closely packed skyscrapers such as the Carlton Centre, Marble Towers, Trust Bank Building, Ponte City Apartments, Southern Life Centre and 11 Diagonal Street.

Johannesburg’s city centre retains its elements of a rectangular grid pattern that was first officially recorded in 1886. Streets are narrow and filled with high rises built in the mid- to late 1900s. Old Victorian-era buildings first built in the late 1800s have been torn down long ago. The 1900s brought along with it the introduction of many different architectural styles and structures. The Johannesburg Art Gallery and Supreme Court Building being two examples. These were important Beaux-Arts structures, with the style put in place by (at the time) colonial parent, the British Empire.South Africa didn’t borrow architectural techniques exclusively from Britain, however. They were also inspired by American models and styles, having built several structures like the ESKOM Building and the Corner House to emulate the prowess of New York City, located in the United States.
