Originally the house had four quarter-shaped moon windows, two on both sides. However, by the time "Amityville 3-D" was made, the owners of the house had decided they did not want the eye windows on the side of the house facing the road, so they modified them to look like small ordinary square windows. All shots of the "eye" windows (except for the most noticeable scene when John and Susan pull up to the house) had to be filmed on the side of the house facing the river.
