Frognal House

[1] During the reign of James I, Dyngleys's grandson, Sir John Dynley, sold the estate to William Watkins, who substantially altered the building in the Jacobean style, reducing the size of the rooms and replacing stone with brick.

At this point the house was on two floors and sloping ground, a square building with a central quadrangle, and an entrance on the northwest side.

[1] In 1649, Watkins sold Frognal House to Philip Warwick, formerly MP for Radnor, concerned that, as a royalist, he might have his property seized by the victorious Parliamentarians in the Civil War.

A print from the time shows a large brick mansion built around a central courtyard, and surrounded by formal gardens, orchards, and tree-lined walkways, with a number of outbuildings that had been connected to the house via construction in about 1700.

Upon his wife's death in 1893 the house passed into the hands of his sister's son, Robert Marsham, on condition that he added Townshend to his name.

The house gave its name to the nearby Frognal Corner, once a crossroads[3] where the Sidcup Bypass crossed Perry Street and, since 1987,[4] a grade-separated junction at the intersection of the A20 and the A222.
