In Milano the CO22 project is located in the centre of the city with all the district facilities and services at hand, with tram and subway lines, in a redesigned Liberty style building, with 4 staircases and 50 apartments. Here the intention is to combine environmental, economic and social sustainability. Therefore: 1) requalify the buildings by reducing the energy needs and CO2 emissions to the minimum; 2) promote economic sustainability as the price is lower than the market price. In addition, the cost per square metre of the cohousing unit also includes all the common indoor and outdoor spaces which have already been furnished; 3) promote social sustainability as common wellbeing is a value, and collaboration, reciprocal respect and creative comparison are functional and necessary to achieve wellbeing and a good life quality. The persons are guided by a facilitat

Common wellbeing is a value to use and love and respect becomes of fundamental importance so that this way of living becomes different from the traditional one. If for young people there is no concept of private property, in this case the social composition that adhered to the project is an exact image of contemporary society. The CO22 Cohousing project was presented in Milan and from the preliminary survey, or feasibility project, the following data emerged: 48 couples (24.6%), 45 families with 3 members (23.1%), 26 families with 4 members (13.3%), 8 families with 4 members + elderly (4.1%), 65 single (33.3%), 3 families of other type (1.5%).

Spaces requested varied, and most required houses with three rooms (40.7%), then four room

In addition, technical spaces for hobbies, cellar, laundry/ironing room and mechanics areas for small repairs. Spaces for solidarity-based purchasing group and spaces for sports and wellness. In Italy, tens of thousands of people have already subscribed to the cohousing website. The group mainly deals with finding available areas and conducts the feasibility study. In this case, the property belonged to the municipality of Milan transferred as contribution to the fixed assets which were then transferred to the banks that must now place these assets back into circulation. Groups may also be formed autonomously. For example, Rome is seeking through the Web for adhesions for cohousing groups: the requests are for a central area of the city where urban cultural services and activities can be easily reached on foot.
