I thought a picture might be helpful for understanding the layout of the house, giving everyone a reference point for each of the rooms. This is my *fantastic* rendering of the downstairs, done with the sophisticated design program called Paint.
Not a single room is to scale, but the dimensions are close enough to reality. All the red boxes are doors, both interior and exterior. Blue boxes are windows, again both interior and exterior because the front window openings are still in the walls after the original front porch was converted into rooms. You can also clearly see the one tiny no light window in the kitchen.
