When we had to define the question for our final exercise related to our future discipline, in my case design, I thought about the famous sentence from Picasso “every kid is an Artist, the problem is how to remain an Artist once we grow up”. Then I thought how the cities would be if kids would be involved in the design of it. Initially I questions myself how I can think as a kid, without restrictions and previous knowledge and it was very challenging because despite I am still quite young somehow I have the impression that I lost that fresh and crazy way of thinking and creating things, I feel stress about other people’s opinion and then I get stacked in my creative process. Then, I asked some kids in a kindergarten to help me by drawing by themselves some images that represent cities as reference. Their drawings were difficult to transfer to design as each one was different, but I extracted several common ideas from their drawings: 1-my project should colorful; 2-the forms should be slightly irregular, as they don't draw straight lines, they draw their own ideas naturally；3-probably be playful and 4-perhaps consider re-cycling materials. Then I selected the oldest part of the city, the Hutongs in central Beijing are very informal settlements, with narrow streets and long history with many old people living in there and in my way of understanding they are kind of playful while safe areas. I tried to bring the kids approach to Fangjia Hutong by building several physical models, in different scales, using the rules I set from kids to design a public space colorful, irregular and recycling materials. I divide the project into Ant-Farms (Supports), The Worms (bridges) and the Blocks (Stairs).
