A few weeks ago, I visited the Siedlung Halen, built in 1961
by Atelier 5 in Herrenschwanden near Bern (CH).
This concrete colony is set in the countryside, on a sunny hillside above a river.
The row houses, with patios and huge gardens are totally crazy.
(Check out the following sections)
They share a lot of facilities, such as a gas station, laundry, kindergarten, community center, pool, barbecue.. 
Judging by the painted walls, political stickers, sculptures in the gardens and Tibetan flags, I think people over there follow a kind of open state of mind.

Best place to live !
