Description of the project: 

Tamassociati has developed in S. Lazzaro di Savena (BO) a new 100% wooden “social building”, putting together excellence and research in the social objectives it sets and the technologies it implements. 12 families form the first Italian co-housing: a new, more socially involved and eco-friendly way to live.

Setting / urban strategy
The building stands on a parcel of 2000sqm and is the fruit of a housing replacement: the land was occupied by a low-quality building which was demolished, with a virtuous process of urban revitalisation.

Programme / functions
12 families were awarded a public sale for the allocation of the parcel, developing a new “social building”. The work combines private accommodations with common rooms and services; they will be used for group activities but also open to community life: a common room, a library, a food storage for group purchases, a laundrette, a workshop, common green areas and a shared vegetable garden.

Design strategy
The families and designers have acted as a “purchasing group”: in this way we have rationalized all the design and building stages, creating advantages in terms of results, costs, site duration, building management.

Environmental sustainability
Community housing has allowed us to opt for a wooden prefabricated system: a 4-storey building fully made of X-Lam. The building-plant assembly is a high-thermal efficiency container that has obtained an A energy class certification. It has a photovoltaic roof able to produce 20 Kw for heating and cooling; it is connected with a state-of-the-art air-water heat pump.

Economic sustainability
The bargaining power of the groups has allowed us to obtain important economies in line with the ambitious programmes that had been set. These processes have resulted – thanks to a housing project based on municipality agreement – in a cost reduction from market value, equal to 39%.

Social sustainability
Co-housing is a conscious response to the social crisis in our cities. Additionally it is also a virtuous intervention with regards to the community because it provides for the revitalisation of a part of a public park adjacent to the parcel.
