18 people attended the seminar from various regions of Greece. Supervisor of the work was the German professor from the University of Kassel Gernot Minke (www.gernotminke.de) with 30 years of experience in research and construction with natural materials (mainly clay) all over the world. We constructed a small building of 16m2 with a wooden loadbearing frame, in the walls of which we used 4 different techniques:
1. Rammed earth: a technique where a wooden mold is used in which a mixture of clay, sand and gravel is thrown and pressed with mallets in layers
2. Adobe: we made bricks from clay, sand and straw, formed in metal molds, dried in the sun and then we built a wall by using clay mortar in between
3. Light-clay: we used a wooden mold in which we threw a mixture of liquid clay mixed with a great portion of straw
4. Wattle & daube: a technique which is similar to the Greek "tsatmas" in which a wall of woven reeds is made and straw, dipped in liquid clay, is knitted around them.
Different types of plaster were tested and a green roof was placed over the construction.
