Vallbona is a neighbourhood set in a rural-to-urban edge next to Barcelona and the Besòs river. The panorama is dominated by some fragmentary built-up areas, major highways and rail tracks leading to the city and industrial or agricultural plots. 

This urban project has been envisaged to deal with time as the most significant variable. Time determines our possibilities to act (or to leave it just as it is). In places of such complexity, situations and urban landscapes overlap in apparent contradictions; nature vs. industry, city vs. dispersion, loneliness vs. great transport routes... It is almost naive to think that the architect's hand can order chaos and give this ever-advancing urban border an unitary design. It is equally naive to think that from our here and now we are able to conceive all the needs of the place in order to solve them. 

Through the proposed urban transformations (which may be successful or not) further decisions will be taken by other social actors.We do not focus on projecting, but on creating opportunities. The urban proposal, in permanent collision with society and users, may arise (or not) new ideas and actions. The concept of ​​time as a limit and the final test of the project.

When all is said and done at once and by one hand, no urban design is possible. The project is meant to disappear into complete silence, as Louise Bourgeois would say.
