interesting, evonne! i have thought about how tiles could be used to create sculptural elements -- peace "towers" and the the like, though not actual "structures." i am interested at base in the root of your idea: ensuring that tiles have some practical impact/use/benefit to those engaged. a very interesting idea and lots of complex details to think about:

• Are there certain climates where this kind of structure would work best?
• How much do you want to "formalize" informal settlements (that's where/how youth dump workers tend to live at least part of the year ie rainy season move back home)?
• Sourcing tile material
• scaling the tile making activity to a volume that would create a structure

Any thoughts/responses? And thanks for jumping in!
