The pathway illustrated by the projects presented here tells the story of the activities undertaken by Marco Facchinetti and Marco Dellavalle over the last decade as well as the evolution that has taken place at the same time in their operative spheres of architecture and urban planning. The evolution of urban-planning practice towards the regional scale in Italy has involved a little revolution and often emphasized the role of municipal entities in territorial planning, sometimes at the expense of the provinces and intermediate bodies. The agenda has also changed over these ten years. Building sustainability has become a key consideration of planning practice, even though the new rules of construction and models of development in force for years now in other countries of the European Union have yet to be established in Italy. Moreover, municipalities are still too busy trying to solve such basic problems as the circulation of traffic in historical centres and the inefficiency of public transport services for any in-depth absorption of canons so evolved as to initiate a general reform of planning design. In this complex scenario, acting with great dynamism, Marco Facchinetti and Marco Dellavalle have put forward incisive plans and projects built up around the two key concepts of design and feasibility that prove truly capable of modifying reality, at least on the local scale. The reflections developed and the projects illustrated here show how planning is able, through the use of design and correct, effective procedures of implementation, to affect local realities by constructing evolutionary scenarios in which progress ensures virtuous productions, new episodes of urban quality in often fragmented areas and new ways of making the most of what already exists. So that planning can always be synonymous with evolution for the contexts to which it is applied.
