At home with Snape

Severus Snape lives, while he is not at Hogwarts, in a house in a dirty and abandoned industrial muggle neighborhood, near a dirty river, in a dreary industrial town of Northern England. The street is poorly maintained, with broken streetlights and some windows of the houses are walled up with boards or are broken. At the end of this street is Snape's house, in front of an old industrial chimney. The house is a brick one and has at least two floors.

Upon entering the house is a small, dark room that resembles an isolation cell. The walls are completely covered with books, most bound in a worn leather brown or black. There is also a sofa in the shabby living room, an old armchair, and a rickety table. The room is lit only by a lamp hanging from the ceiling candle that emits a faint glow of light. One of the bookshelves is actually a secret door, pointing the wand (and possibly thinking of a spell) opens it with a bang, revealing a narrow staircase that ascends to the upper floor. There is another secret door in the room that leads to a room where Snape keeps elf made wine.
