Atlantic gardens and swimming pools constitute one of the most relevant features of a new phase in the history of the urbanization process in the Metropolitan Region of Barcelona, coinciding with the real state madness, by which the traditionally compact urban form typical of Mediterranean cultures lose ground to more disperse patterns of settlement characteristic of Anglo-Saxon countries. The change in the urban form also bears a noticeable relationship with changing lifestyles more and more akin to the suburban landscapes of many areas of Atlantic Europe and above all North America. Low density housing with gardens and swimming pools are associated with a better quality of life and considered as positional goods, giving the owners the status and prestige that is absent from other urban forms. In this paper I will therefore illustrate how new suburbia lifestyles linked to water use are gaining terrain in a geographical, social and cultural context that traditionally has been quite conservative in the use of this resource. I will show also how new, water-related lifestyles are endowed also with a strong income component. Thus high income households prefer and can afford more water-consuming Atlantic gardens with swimming pools whereas lower income households have to resort to more climate-adapted species in what constitutes a growing socio-spatial differentiation.
