On the 8th June I delivered a Street Training workshop with the support of Amy Pettifer and Viola Carnelutti from muf architecture/art to a group of 25 school children. The session began with an explanation of how joy shapes cities and young people and children are experts on joyful behaviour. I explained that was why I wanted to learn with them so as to gather their ways of being in the street and pass them on during the architecture biennale.
