The answer to this can be found in Chapter 20. In this chapter, Pip is going to Mr. Jaggers's home and office to find out what is to happen to him -- he has a great expectation of what is in his future.
The major description of what he finds is that it is dismal. The whole are is very run down and unpleasant. Jaggers's room is tiny and dark. The chair that Jaggers sits in when he consults with clients reminds Pip of a coffin. On shelves are weird things like the casts of distorted faces. The skylight is kinds of twisted "like a broken head." The houses around Jaggers's look twisted.
