Du skyline des CBD à la création de pôles de gratte-ciel résidentiels dans les villes nouvelles d’Afrique=From Skylines to Skyscrapers Hubs in New Cities in Africa

This paper investigates verticalization processes in sub-Saharan Africa, its forms, and consequences, particularly residential skyscrapers in new cities. The link between verticalization and new cities is complex and understudied in African contexts. For this reason, the paper analyzes different real estate projects following two criteria: their size and their attitude towards the vertical dimension. This division produces a matrix with four scenarios that are presented in detail in Part 4. The analysis shows that only some new cities are bound to take a vertical dimension, but that most of the vertical projects are designed as enclaves, physically separated from the existing city. More than veritable skylines, these projects take the form of skyscrapers hubs that define a specific urbanization model.
