Also, even though a diverse group may have a strong desire to work, eat and live together it is often hard to find consensus between different cultures, age groups, couples and singles. This size equates to several families, and provides increased opportunities for improved economic viability, social interchange, and self-reliance in food. More skills can be exchanged. Tools too expensive for a single family to buy can be group purchased and shared. Bulk-buying becomes a viable and sensible option.
Good relations are necessary more between the families than between individuals.
There are many successful examples of co-housing projects with this size population in Denmark. My own experience of these projects is that this number of households averaged out at around 40 people per project. Larger co-housing projects seem to favour a clustering concept, gaining the favourable economic aspects of a larger population but recognising that smaller groupings offer social advantages. At this size individuals cannot behave in a family relationship pattern. It is not possible to have a say in all decisions, and complete consensus is rare.
