This article describes the development plan which has been drawn up to reurbanise the seafront “Área de las térmicas dels Besos”. This combines residential and tertiary uses, infrastructure and also free areas for museum uses in the great industrial building of the old power station. The current plan will make it possible to gain a kilometre of beach for the use and enjoyment of the citizens of Barcelona. It will also provide the municipality of Sant Adriá de Besos with access to the sea. The most original contribution of this plan lies in its aim to collaborate to sustainable urban development. It plans to do this by incorporating strategies that will make it possible to generate urban growth with a minimum environmental impact and with low carbon emissions.
