Modular / Temporary / Flexible / Multi-use / Open / Accessible / Family Resemblance are some key characteristics of what i believe is a good design. Especially when referring to out door, urban, public zones.
If you follow and integrate them into your design thinking and methodology as basic starting points, your design will be able to live and develop according to its on-changing environment needs. The product/service/space you design will just be a starting point and a good suggestion. In some extent it will be open for users, with different influence scales, to influence and change.
