Early this year my wife and I traveled to VA. to attend my uncles funeral. On our last day there we toured Washington DC and I wanted to see the exorcist house and stairs. We walked the stairs (the film doesn't do it justice the damn thing is steep and a pain to walk up) and took pictures in front of the house. After getting home I looked at the pictures and what the house looked like in the film and realized that an entire section of the house was missing (the room/wing where the exorcism took place/filmed was gone). My question is was the house remodeled since the filming or was that wing of the house just a set that was built onto the house for the movie?
