Surgical interventions for urban transformation I is a design studio program developed with students from Clemson University and Texas A&M students at the Barcelona Architecture Centre-directed by Miguel Roldán- The program is proposed and coordinated by Jordi Mansilla and Toni Montes. Francesc Muñoz, Teresa Galí, Roger Paez and Alejandro Quintilla participate in the program as lecturers. This program explores opportunities for deep transformation in the old industrial Poble Nou district of Barcelona, that the city is promoting as the new technological district renamed 22@. The studio methodology uses operative mapping techniques to detect opportunities to insert in the old and under used fabric low scale public space and public facilities to generate larger scale transformations and revitalisation. This strategy is proposed as an alternative to the massive intervention that is taking place, that implies large investment for minor revitalisation. The results of this last double edition have been recently published.
