Wyatville's own preference ran to Gothic architecture, but George, who had led the reintroduction of the French Rococo style to England at Carlton House, preferred a blend of periods and styles, and applied this taste to Windsor.Ireland, p. 92; Nicolson, p. 79, 172–173. The terraces were closed off to visitors for greater privacy and the exterior of the Upper Ward was completely remodelled into its current appearance.Robinson, p. 89. The Round Tower was raised in height to create a more dramatic appearance; many of the rooms in the State Apartments were rebuilt or remodelled; numerous new towers were created, much higher than the older versions.Robinson, pp. 91, 93. The south range of the ward was rebuilt to provide private accommodation for the king, away from the state rooms.Robinson, p. 96. The statue of Charles II was moved from the centre of the Upper Ward to the base of the motte. Sir Walter Scott captured contemporary views when he noted that the work showed "a great deal of taste and feeling for the Gothic architecture"; many modern commentators, including Prince Charles, have criticised Wyatville's work as representing an act of vandalism of May's earlier designs.Robinson, p. 92; Prince Charles, quoted Nicolson, p. 126. The work was unfinished at the time of George IV's death in 1830, but was broadly completed by Wyatville's death in 1840. The total expenditure on the castle had soared to the colossal sum of over one million pounds (£817 million in 2008 terms) by the end of the project.
