The interior of the house today is very different from its original appearance in 1851–52. This is mainly due to the 1st Lord Astor, who radically altered the interior layout and decoration c.1894–95. Whereas Barry's original interior for the Sutherlands had included a square entrance-hall, a morning room and a separate stairwell, Lord Astor wanted a more impressive entrance to Cliveden so he had all three rooms knocked into one large one (the Great Hall). His aim was to make the interior as much like an Italian palazzo as possible, which would complement the exterior. The ceiling and walls were panelled in English oak, with Corinthian columns and swags of carved flowers for decoration, all by architect Frank Pearson. The staircase newel posts are ornamented with carved figures representing previous owners (e.g. Buckingham and Orkney) by W.S. Frith. Astor installed a large 16th-century fireplace, bought from a Burgundian chateau which was being pulled down. To the left of the fireplace is a portrait of Nancy, Lady Astor by the American portraitist John Singer Sargent. The room was and still is furnished with 18th-century tapestries and suits of armour. Originally the floor was covered with Minton encaustic tiles (given to the Sutherlands by the factory) but Nancy Astor had them removed in 1906 and the present flagstones laid. Above the staircase is a painted ceiling by French artist Auguste Hervieu which depicts the Sutherlands' children painted as the four seasons. This is the only surviving element of Barry's 1851–52 interior and it is believed that Lord Astor considered it too beautiful to remove.
