I'm colaborating (as a volunteer) in Impulso Urbano (http://www.impulsourbano.org.mx/) is an organization of the Architecture School from Tec de Monterrey (Is a university). We beging our process in the Design Courses, where the students build a 1:1 prototype , then we select the project who has the highiest probabilty of successs to be builded and finally with other group of volunterr students (majorie form Architecture or Civil Engenier) we build the proyect.
Is more "complex" than that �� but in general terms is how Impulso Urbano works.
Would be great if you can share some of that DIY instruction.
Have you implemented this idea into a public space like pocket, linear, neighborhood parks? or even indoor spaces? And how that could be escaleted? I´m imagining like a kind of DIY manual of differents "elements" that can be builded or ensambled, for example the "tree dome", benches, etc.
