 By the 1830s the Wentworth family had made many visible improvements at Vaucluse, including turrets on the house, a sandstone stable in 1829 by architect George Cookney, a large kitchen wing and convict barracks.Conrad Martens' 1840 sketch from Vaucluse Bay shows a clear view to the residence and what appears to be a well-established climber (possibly "Wisteria sinensis") over the verandah.Wentworth did further work on the main house in the late 1840s including adding the verandah crenulations.
