In February 1671, Nell moved into a brick townhouse at 79 Pall Mall. The property was owned by the crown and its current resident was instructed to transfer the lease to Gwyn. It would be her main residence for the rest of her life. Gwyn seemed unsatisfied with being a lessee only—in 1673 we are told in a letter of Joseph Williamson that "Madam Gwinn complains she has no house yett." Gwyn is said to have complained that "she had always conveyed free under the Crown, and always would; and would not accept house till it was conveyed free to her by an Act of Parliament." In 1676, Gwyn was granted the freehold of the property, which remained in her family until 1693; as of 1960 the property was still the only one on the south side of Pall Mall not owned by the Crown.
