A little more than a year ago, Barcelona City Council presented an agreement sealed with the owners of the plot where the old Mercedes-Benz factory used to be in Bon Pastor, Conren Tramway, to convert this space –in disuse since 2007– into a new estate with up to 1,450 homes (3,500 residents), universities (some 2,000 students and 500 professors) and economic activity to attract over 4,000 workers. This is what the promoters of the project claim will be the city's first eco-district, because they want plenty of green spaces and no traffic, becoming an urban link between Sant Andreu de Palomar and Bon Pastor. But once the project's specifics have become known and, above all, the developer has revealed its first simulations, neighbourhood tensions have arisen over to overcrowding concerns. The City Council insists, in the face of criticism, that nothing is definitive yet.
