various officers of the Royal Household until 1843, and from 1873 to 1931. The grounds extend to 98 acres (40 hectares), partly under its own head gardener, but mostly the responsibility of the Crown Estates Commissioners. While the house has grown piecemeal since the 1840s, and remains relatively small and informal, the grounds have a unifying plan. This was the result of work undertaken by the Duke and Duchess of York in the 1930s, with the assistance of Sir Eric Savill, of the Windsor Estate. In 1931, King George V granted Royal Lodge to the Duke and Duchess of York (later King George VI and Queen Elizabeth) as a country retreat. Wings were added on each flank in the 1930s.

The lease agreement required Prince Andrew to carry out, at his own expense, refurbishments estimated at £7.5 million at September 2002 prices, excluding VAT (this sum was exceeded). It also provided for a premium payment of £1 million. The National Audit Office (NAO) report into the lease agreement states that the Crown Estate's independent advisors had advised that the refurbishment work would cost at least £5 million and that the prince should be given the option to buy out the notional annual rental payment (set
