Symmetrical FacadeThe typical form of original Federal, or Adam, houses is a simple box shape, usually two to three rooms deep, with a symmetrical arrangement of doors and windows, especially on the front. Later additions to the sides and rear are common. Today's update: Symmetry is pleasing to the eye, no doubt about it. If you're house's facade is asymmetrical, you can achieve a similar affect by focusing on one area, such as the entry. Try a pair of lanterns, planters, or window boxes for an orderly effect.
