The first prize winning ‘e(CO)stratègia’ proposal for the ‘Les 16 portes de Collserola, porta 13′ Competition weaves biological and urban flows in order to improve society and ecosystem together as a whole. Designed by Sau Taller d’Arquitectura, their concept aims to define the edge between the city and the mountains as a surface, a space occupied by domesticated fields, a place between nature and city where you can find community vegetable gardens, and open air green spaces. Therefore, this domesticates nature between the concrete sense of the city and the wildness aspect of the natural park. For images and architects’ description after the break.
The competition was about rethinking the border between the natural park of Collserola and the City of Barcelona. It has been divided this edge in 16 parts and call it doors. There has been proposals for each door, related to the particular context and situation of this part of the edge. Taller Sau’s proposal is for the 13th Door, located in the north of the city of Barcelona . This site is also one of the main entrances of the city by car. All these highway lanes have fragmented the urban weave and isolated the neighborhood of la Trinitat from the city. At the same time the green spaces system has been broken up by the road system and lost its flow.
The other part of the proposal was to recover the flow of the green spaces system of Barcelona metropolitan area, connecting the Collserola natural park with Besòs river and Serra marina, the mountain system on the other side of the highway. Recovering the valley section of the place and getting a stronger and continuous ecosystem. We also include the green spaces system of the city of Barcelona to this huge green system. This would also connect “La Trinitat” neighborhood to the neighborhoods of its boundaries in order to solve its isolation situation.
