The physical house of the Usher family is slowing deteriorating just like the Usher family is. The Usher family has no outside descendants, so by method of incest, the previous family members married off and reproduced with each other to keep the family as tight knit as possible. Roderick Usher called upon the narrator as he was suffering from some sort of debilitating illness. When the narrator got to Rodricks house, he described the house as very worn out, dull, ghostly and dark, just like Roderick himself. As the story progresses, Roderick and his sister become progressively more ill and Madeline even “dies” and gets trapped buried underground for a week. As this all happens, the Usher family house wears down more and slowly starts to crumble.
