As the name suggests this is nothing new. Basically this is a plywood hexayurt with framing and earthen brick (CEB) foundation. It is hard pressed to improve the hexagon shape for cheap building ideas. The Native Americans knew this and used this design shape for their hogans. The 6 wall and 6 roof panels can be unscrewed and the whole building relocated without much difficulty. A floor can be added later without much hassle. Materials consist of 43 2x4's 6 sheets of plywood or any ridged 4x8 sheeting and a pile of bricks. All of this is available through out the world.
