In downtown Johannesburg, daring entrepreneurs have found that they can profitably reintroduce previously abandoned high-rise buildings back into the market by converting them into working-class rental accommodation (Mosselson, 2019). New markets have also been 'discovered' on the city's periphery where owners of historically agricultural land supply entry-level detached housing to first-time black homeowners (Butcher, 2019). In the north east of the city, a Shanghai-based firm-attempting to diversify away from the flagging Chinese property market-bought an undeveloped site and planned to build a 'new city' for middle-class residents and commerce (Ballard and Harrison, 2019). Meanwhile, city authorities have worked to attract affordable housing developers into transit-oriented corridors in central parts of the city (Todes and Robinson, 2019). A core commitment of the post-apartheid state has been the transformation of South African cities away from their segregated histories (e.g. RSA, 2012, 2016). Yet after a quarter of a century of democracy, many officials are exasperated over the persistence of segregated urban forms. As Harrison and Todes (2015) note, spatial transformation cannot be decreed through policy but must rather reckon with the ongoing production of postapartheid urban space, not least by individual residents and the private sector. In South Africa's largest conurbation, in which Johannesburg is embedded, the number of residential buildings of all sizes and types has increased by 60 per cent, from 2.1m in 2001 to 3.4m in 2016 (Hamann, 2018), and commercial buildings have increased by 30 per cent over the
