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.
