We are currently working on our cob studio. The size will be approximately 10x20 feet (interior dimensions). The floor plan will be in the shape of a spiral. We will first build a circular structure (10ft interior diameter)and will later construct a wall that radiates outward to create the spiral "arm". Once the circular structure is complete, we will move in and use it as our shelter while we build the connecting spiral arm. The spiral arm will serve as a windbreak. The exposed southern face (between wall and circular structure) will eventually be closed off by windows and possibly an entry door. We will attempt to keep construction cost below $1000.
