we've long been interested in living in a cohousing group, and there are many of them in Denmark (where the concept originated, after all!) so I'm currently trying to see if we can obtain a rental with a group in greater Copenhagen.
I've found some sites (such as this one) that show homes available in such places ('andels' = cooperative/shared, 'bolig' = house, hence 'andelsbolig') but I'm told the waiting list can be long for such places. It would be a great way to immerse quickly in the culture there if we can manage to find such a place, so, fingers crossed!
