Pip visits Wemmick's house in Chapter 25 of Great Expectations. The house, which Pip observes as being the smallest house he has ever seen, resembles a tiny castle, complete with a flagstaff, drawbridge and moat, and a gun that fires each night at nine o'clock. Wemmick explains that he has built his house to his own specifications, and Pip notices the pride with which Wemmick describes the structure. Further, Wemmick leads Pip around the grounds:
Then, he conducted me to a bower about a dozen yards off, but which was approached by such ingenious twists of path that it took quite a long time to get at; and in this retreat our glasses were already set forth. Our punch was cooling in an ornamental lake, on whose margin the bower was raised. This piece of water (with an island in the middle which might have been the salad for supper) was of a circular form, and he had constructed a fountain in it, which, when you set a little mill going and took a cork out of a pipe, played to that powerful extent that it made the back of your hand quite wet.
Wemmick describes himself as a "Jack of all Trades" and boasts that he is his own carpenter, plumber, and gardener. He also introduces Pip to his father, the Aged Parent, who also resides in the house.
Ultimately, this visit to Walworth shows Pip a completely different side of Wemmick. At work, Wemmick is all business; at home, he is a kind, caring man who loves his house, his father, and his life.
