At the beginning of the 18th century Walnut Tree Walk was a lane leading out into the fields from Lambeth.
Simon Harding - a gardener - had a cottage there with a small-holding of just over three acres at the beginning of the 1700s. There was no other development until 1755, when Robert Hardcastle, who held land elsewhere in the parish, was granted a 61 years’ building lease of ground on both sides of the road by the St. Olave trustees of the Walcot Estate. Walnut Tree Walk then extended on either side of Kennington Road.
