The event was conceived by Jan Kattein Architects, Enfield Council, and St John & St James C of E Primary School in Edmonton, North London . On 23 July 2021 we closed the street in front of the school to cars for a day to seed the idea that space in the city needs to be first and foremost reserved for people. Chalk drawing, experimental den building, an outside gallery of student artwork, an ice-cream tricycle and a pop-up zoo proposed alternative uses for the street with a view to permanently transform the street into a space for play, social interaction and biodiversity in the future.
