We have been learning about living sustainably. One of our ideas for this is to live in Eco houses. My Eco friendly house will have two rows of branch walls and the roof will be made out of grass and leaves sitting on a row of branches wired together. There will be a wind turbines for electricity and solar panels to give you heat instead of heaters because the use power. The windows will be double glazing so the heat inside the house will not escape. There will be a ground heat pump to give you hot water. In between the two rows of branches in the wall there will be insulation to keep the heat in from going through the walls. The floor will be bambo with insulation underneath it. There will also be a water butt to supply the water.
