Mr. Utterson lives alone in what is called a bachelor house on Gaunt Street in London. He lives by a church that is "conveniently near" to his home and from which he can hear the bells ringing.
There is an actual Gaunt Street in London. It is located near the Elephant and Castle tube (subway) station in the area of London called Elephant and Castle near the Imperial War museum in west London.
As a lawyer, Mr. Utterson is comfortably well off, and people like to be entertained in his comfortable but unpretentious home and drink his good wine.
Mr. Utterson also likes to walk the streets of London and becomes so curious about Mr. Hyde and his relationship to Dr. Jekyll that he ends up frequently going past Jekyll's house, looking for the mysterious Mr. Hyde.
Mr. Utterson, Dr. Henry Jekyll's lawyer, lives in London, England, in a "bachelor house" of his own. He must live relatively close to Mr. Edward Hyde's residence because, on one of his Sunday walks with his kinsman, Mr. Richard Enfield, they pass his home, which Enfield refers to as the "Black Mail House." Enfield knows that it is Hyde's home because he's seen this man use a key to get in. However, he recounts a story wherein Hyde essentially trampled on a young girl, and when pressed to offer the family some financial remuneration, he went into the house and returned with a check written out by Dr. Jekyll. Thus, Enfield comes to the conclusion that this horrid little man must have some dirt on Jekyll from his younger days that he is using to blackmail the good doctor.
Utterson also appears to live pretty close to Dr. Lanyon, another of Dr. Jekyll's oldest friends, because, on foot, he sets "forth in the direction of Cavendish Square" to ask Lanyon about Jekyll's relationship to Hyde. Cavendish Square is in London's West End.
