In what movie does a lady kill her husband &start adding onto the house then it adds onto itself &it kills ppl?

I think it's in a mansion and the lady's maid is cheating on her husband. Then the maid and lady push her husband out the window. The lady is told to add onto the house to keep from going crazy. Next the house starts adding onto itself and rearranging things like where walls and doors were. The house does that to trap people and kill them.|||Rose Red by Stephen King.
