The Earthship is an autarchic housing concept developed in the US 30 years ago by the architect Michael Reynolds. An earthship is able to get all the needed input directly from nature (energy, water, food, air) and is able to give back an output that can feed the natural cycles. Nowadays there are more than 200 Earthship worldwide. In 2009 the first Dutch earthship has been built in Zwolle. 2012Architects were involved in the design and could learn from Earthship Biotecture how to build an autarchic system. From that experience the office has kept working on the concept in order to develop self-sustainable systems for the lowlands context.
