Old in the sense of former rather than ancient for, despite its appearance, this is the most modern room in the house, having been added for Granville Leveson Gower by Philip Hardwick in 1856. It is a Victorian antiquarian set piece with its dark woodwork, large mullioned bay window, old oak furniture, and copious heraldic decoration on the frieze with the arms of all the owners of Titsey and their wives, down to the end of the nineteenth century, together with the family's more important connexions. The over-mantel contains a finely carved sixteenth century central panel with the initials W.G. and the quartered arms of Gresham and Ipswell. The Victorian panels on either side show the monogram of Granville Leveson Gower and his wife Sophia (the daughter of Lord Leigh of Stoneleigh Abbey, Warwickshire). The oak panelling round the walls also incorporates genuine brought-in woodwork including a single linen-fold panel.

Hanging over the sideboard are four carved panels which are English Renaissance work with classical heads, stylised floral decorations, and the Gresham motto Fiat Voluntas Tua (Thy will be done). They are thought to have come from the old house, and were engraved in
Brayley's History of Surrey. The double portrait facing the fireplace is by David Shepherd, of the late Richard Leveson? Gower and his brother Thomas together with their white Highland Terriers, Heather, Robbie and Slipper.
