4 Privet Drive was the street address of the home owned by Vernon and Petunia Dursley. They lived in this home with their son, Dudley as well as their nephew, Harry Potter, son of Lily Potter, Petunia's late sister and Lily's husband James Potter. Privet Drive lies in the village of Little Whinging, which was located in the county of Surrey, near London in the southeast of England. The neighbourhood consists of a number of almost exact replications of the Dursley residence — row upon row of executive houses for executive people.

Albus Dumbledore first visited the house in 1981, delivering the baby Harry Potter to be put into the Dursleys care after the murder of his parents. Harry wasn't the only thing that Dumbledore left behind him on this occasion: he also invoked strong magic granting Harry absolute protection from Lord Voldemort and his Death Eaters whilst he was at the house, as long as Harry could still call Privet Drive his home, until he came of age on his seventeenth birthday.
