The terms “brown fields” and “green fields” appeared in Western Europe some years ago, when planners were looking for opportunities to manage vital urban areas in more efficient ways. There is no doubt that new urban needs will continue to demand new accommodating spaces. The present paper aims to show that urban configurations offer additional fields like grey-fields, orange, underground, sky, bank, donor, energy, time-fields etc which designers and decision makers, have to be aware of, in order to contribute effectively to the regeneration and vitalization of our cities.
