Possible church goof

As I can recall, they show the exterior of the church from about four different angles.

One angle shows the "back" of the church, with the doors leading out.

A second angle shows the "Right side" of the church, with the doors to the left of the screen, and the rounded end where the altar would be on the right side of the screen.

A third angle shows the anchoress's booth, with a wall on the left side of the window into her booth. This wall extends out for a bit, and then forms a right angle.

A fourth angle shows the "Back" of the church, with the doors leading out, and the anchoress' window visible on the right side of the church.

All this makes pretty good sense. The church started out as a long U shaped building, with the altar in the curve, and the doors at the other end. The priest may have had an office on the "Left side" of the altar, and the Anchoress's hut would be added in on the "Right side," to form a sort of cross shape, similar to the floor plan of a larger cathedral.

What I don't understand is how, after the anchoress' room was added on, they could continue to show exterior shots of the "right" side of the church, with no room for the anchoress showing. I'd swear I saw this at least twice.
