Carrie's room is apparently the attic of the house. It is a fairly large room, having enough space for five people to move around freely. In her room is a bed, a desk with a computer, a TV, a wide selection of shoes, a chandelier hanging from the ceiling, a game console, and an assortment of gothic/emo paraphernalia (books, posters, clothes, etc.).
His room look like his liar, But he had a bed, a TV, a window, and a door.
