• The aim of this research is to study the emergence and evolution of the multi-storey extension (MSE) of socialist blocks of flats in the form of additional storeys or lofts on top of host buildings, which is seen as a dominant model of post-socialist spatial change in inherited multi-storey housing areas in Serbia. Relying on an analysis of empirical data sources, interviews, observation and a comparative analysis, the paper investigates the MSE as a predominantly self-organising process. It also considers its manifestations at different operational and spatial levels in the study area of the city of Nis. It is argued that the MSE, under conditions of low economic capacity, an indifferent attitude of local authorities, an inconsistent legislative environment, and the market as an essential driving force of the process, results in uneven urban transformations, both in physical and social terms.
