Robartes acquired about of land across the Cross Deep Road opposite the house, extending west to the line of present-day ''Radnor Road'', and which he connected to the riverside property by a tunnel like his celebrated neighbour to the north,

A notable flood that occurred on 12 March 1774 is commemorated by a stone plaque in the remaining wall of the house. After Robartes' death, Radnor House was left to Robartes' steward, Frederick Atherton Hindley. Following his bankruptcy in 1779 and death in 1781 there followed a period of uncertainty about its ownership due to disputes over title resulting from Hindley's debts. In 1785 it was purchased by Sir Francis Basset who held it until 1793. Subsequent owners included Lady Marjory and Lady Anne Murray, John Ivatt Briscoe and, possibly for a short period, Francis Needham, 2nd Earl of Kilmorey before he bought and lived at the neighbouring ''Cross Deep House''. Between 1846 and 1847, under the ownership of wine merchant, William Chillingworth, Radnor House was remodelled in an Italianate style by Henry Edward Kendall Jr. By the end of the 19th century, Radnor House was becoming dilapidated. Purchased in 1902 by Twickenham Urban District along with the adjacent properties, in 1903 the gardens were opened to the public and remain today as Radnor Gardens. The house stood empty for some time and was briefly used as a school clinic. The council's reluctant deliberations on renovation of the house were resolved by its total destruction by a 250kg delayed action high explosive bomb which fell through the house at 10.30pm on 16 September 1940. Only a few walls remain, indicated by commemorative stones, as do the
