Nearly half of all the office development taking place in South Africa right now is happening in Sandton, cementing its claim as the richest square mile in Africa.

The latest research in the South African Property Owners Association Office (SAPOA) Vacancy Survey for Q4:2016 showed that 48% of new commercial property development in the country is taking place in greater Joburg’s central finance district.

What makes this figure even more extraordinary is that no other area in the country can match its growth, notes Sandton Central Management District (SCMD) – which manages the public urban spaces of the financial hub – with the closest contender below 9%.

Among the new office developments joining Sandton Central is Sasol’s new 67,000sqm 10-storey head office. Developed by Alchemy Properties and Sasol Pension Fund – the distinctive corporate headquarters were completed in December 2016.

Sasol Place enjoys a prime position in Sandton Central at 50 Katherine Street.
