Flexible Plaza is a modular and durable urban element that allows the agile and reversible extension of sidewalks. A platform and planter system capable of adapting to various arrangements, both in alignment in parking lanes or chamfers and intersections. And designed with the aim of guaranteeing universal accessibility by creating environmentally comfortable spaces around strategic spaces such as terraces or school facilities. Flexible Plaza has been a ground-breaking in the transformation of the street terraces of bars and restaurants -spaces previously taken up by cars- in the city of Barcelona.
