My 1st go at community participation in urban design was in Hulme in 1993, developed further with the design of Homes for Change. With urbed this was developed into  a methodology we called Design for Change. Residents analyse their places, pick places they like for inspiration then model it in plasticine. I then built 3d models of these and superimposed them onto overhead views. Some of this has been realised, but there's still decades to go.
