The advent of modern utility systems together with improved transport infrastructures and information technologies introduced new spatial arrangements and temporalities in the territory. In time, these reveal a notion of urbanisation that does not only takes place in or directly adjacent to the traditional (territorially bounded) city, but in which co-evolving processes lead to differentiated territorial arrangements. Belgium’s distributed urban condition – the ‘nebular city’ – emerged out of the interplay of such multiple territorial arrangements. Often, it is explained by a historical roots in policies of industrial dispersal, while historical efforts to actively accommodate and organise the territory from the broader perspective of urbanisation are assigned a secondary role only. This article, however, takes a close look at two projects from the 1930’s that took the emerging condition of dispersal as their starting point and which both reflect on the role of urbanisation in the reproduction of the conditions in which industrialisation, among other processes of modernisation, can take place. In particular aspects surrounding the Belgian electrification are examined. Although not one of their main drivers, the electrification is both intertwined with the rise of industrial production and the development of an urban modern lifestyle. Only in the 1930’s, however, Belgian spatial planners started to explore issues concerning the distribution of electricity and its spatial and economic consequences. Both projects are embedded within the international debate on the functional city and present Belgium as a particular case. They show the general delay and mismatch between the process of industrialisation and urbanisation because of the nation’s chosen development path, both in spatial and temporal terms.
