Situated in the rural Altmark area of former East Germany, Sieben Linden is a community-initiated eco-village based on principles of self-sufficiency and self-determination, with accommodation for 300 people on completion. The buildings have been constructed using straw-bale, timber and clay and include the largest straw-bale building in Europe: a three storey apartment block for 20 people, and the first in Germany to receive full regulatory approval.

It was a Finalist in 2007 for the World Habitat Awards.
