While the research team is doing the testing of Bale Haus, Mr. Zaker has gone ahead and built a house of straw and clay for himself for a weekend retreat. He has built it all by himself. Well, he had only three laborers, I guess. Drawing inspiration from peasants dwelling in fifth century, he has done it in this hi-tech era. Using a plywood plank as a surface to mix and a pitchfork spoon to mix with, he used to mix a bale of straw with just a right proportion of clay or mud. It is an awesome example of sustainable building.
