The City of Tomorrow is an educational project whose objective is that from childhood and with the game as a tool, becomes aware of all the scales of the common: the tangible and intangible heritage, architecture, urbanism and landscape. It is necessary that childhood be present actively in the processes of construction of the common space (square, neighbourhood, city ...); for this it is fundamental that they discover and know the value of their environment; At the same time, it is necessary to provide them with tools to develop their creativity, from art and architecture. The aim is to provoke in them the awakening of a new look on the spaces in which they develop their life. At the same time that from the architectural discipline discover a new vision of the city, a vision that will bring us who will be the inhabitants of tomorrow. To work with the youngest and to be able to understand and transform their environment, we have based on strategies of art and architecture. Our tools of transformation will be the POINT, the LINE and THE PLANE (based on Kandinsky); to which we will add the THREE-DIMENSIONAL ELEMENT, rethinking the “gifts" of Froebel's learning process, The children will tell us what their city is like, through a large golden frame, like O'Grady did. They will work with the human scale and its relationship with the city, based on the experiences of Yves Klein. His perception of the nearest environment will be modified, using the phenomenon of “defamiliarization" of Viktor Shklovski.
