One project (still unfinished) is also discussed : the house of Jacques-Joseph and Jean-François Champollion in Vif, near Grenoble, which must be restored an transformed into a place of memory. Through these examples, we will attempt to show how the restoration of old buildings in city centers (such as Lyon, World Heritage of UNESCO), may be part of a sustainable development objective. Although these projects are formally quite different, we find the same working method, a common theoretical approach. We project the existing in a global ecological approach. This leads, via the analysis and the project, to the understanding of the multiple values of architectural heritage (art and history value, authenticity, memory, creativity, urban and social role ...). The approach called «the critical and creative restoration», inherited from the School of Rome (Giovanni Carbonara) provides us with a set of guide lines that we often refer to.
