100in1Day is a global movement of citizen driven change, where people take ownership of their city and together, create a better place to live.
The concept is simple, 100 urban interventions in 1 day. An urban intervention is an activity, project or installation that temporarily improves a public space and demonstrates how a community might achieve more lasting positive change. It may be led by an individual, community-based group, or an organization.
Projects can be practical, like planting trees or pop-up street furniture. They can be social, like hosting a block party. They can be artistic, like flash mobs or yarn bombing. They can challenge us or fix a problem. They can be as big or small as you want. All projects must be safe, legal and inclusive.
