Knock, Knock, it's the front door. If you recall from the last photo, this is a continuation of the same wall in the previous photo. The big plan is to place a fan over the door (this is the north side of the house) and to blow air in the house. There are vents on the south side of the house and inside the dome which will hopefully pump hot air out when the fan is on. Oh yea, I know it's winter, but in middle Georgia, winter comes and goes quickly. Summers linger for a much longer period. .
