This research examines the dynamics of spatial transformations in highly urbanized areas and in particular the urban agglomeration of Ghent (Belgium). To this end we go back 50 years in time (1963-2013). The hypothesis is assumed that three major spatial transformations take place during this period: (1) the population increase leads to sub-urbanization or the spreading of functions around the city center until the 1980s and (2) is followed by a period of compaction processes in which remaining open areas are filled within the suburban area. It is mainly about new construction. This condensed nebula - which presents itself as a city edge – (3) finally, together with the city core, transforms both in nature and in use of the existing built-up tissue. This mainly concerns renovation and reuse. The dynamics of these processes can be reconstructed on the basis of building and allotment permits. Based on this, neighborhoods can be distinguished with low or high dynamics regarding transformations. Finally, it will be investigated where transformations will occur in the future. Socio-economic characteristics of starters on the residential market can be an indication of expected transformations in the future in other neighborhoods. The article introduces the concept of Napoleon plots to carry out statistical and spatial analysis. Dynamics and patterns are mapped.
