Am I completely insane to design an attached greenhouse that covers a bedroom window or two. The best place for my greenhouse appears to be attached to the end of the house where there are two bedroom windows. The house wall will serve as the "north" wall of the greenhouse and won't be modified. Afterwards, one could enter the greenhouse from the bedroom window, but one would be in really big trouble to do so (except in a fire emergency). There's other bedroom windows in the room that exit thr front of the house.
