 A handful of rooms in the modern State Apartments reflect either 18th @-@ century or Victorian Gothic design . The State Dining Room , for example , whose current design originates from the 1850s but which was badly damaged during the 1992 fire , is restored to its appearance in the 1920s , before the removal of some of the gilded features on the pilasters . Anthony Salvin 's Grand Staircase is also of mid @-@ Victorian design in the Gothic style , rising to a double @-@ height hall lit by an older 18th @-@ century Gothic vaulted lantern tower called the Grand Vestibule , designed by James Wyatt and executed by Francis Bernasconi . The staircase has been criticised by historian John Robinson as being a distinctly inferior design to the earlier staircases built on the same site by both Wyatt and May .
