Goofs

The side of the Wilsons' house closest to the Mitchell residence has an architectural inconsistency between front and back views. When viewed from Elm Street, the Mitchells' driveway appears to directly border the outside wall of the Wilsons' living room. However, in all but season 2, there is a door in the living room that exits toward the Mitchell residence. Beyond that door is a fence, sometimes with a gate that exits into the corner of the Wilsons' front yard. Viewed from the front, that gate could not exist. It would come out into the corner of the Wilsons' yard where the front yard, living room and fence meet the edge of the Mitchells' driveway.

Throughout the series, the outside design of the Wilson's house shows two windows on each side of the front door. On the inside of the house there is no window by the front door - the window is around the corner to the left and bigger than the one by the door seen on the outside. The house design on the inside doesn't match up to outside design.
