1860s Cowper was keen to sell the estate. Edward VII In 1861 Queen Victoria's eldest son and heir, Albert Edward, was approaching his twentieth birthday. Edward's dissipated lifestyle had been disappointing to his parents, and his father, Prince Albert, thought that marriage and the purchase of a suitable establishment were necessary to ground the prince in country life and pursuits and lessen the influence of the "Marlborough House set" with which he was involved. Albert had his staff investigate 18 possible country estates that might be suitable, including Newstead Abbey in Nottinghamshire and Houghton Hall in Norfolk. The need to act quickly was reinforced by the Nellie Clifden affair, when Edward's fellow officers smuggled the actress into his quarters. The possibility of a scandal was deeply concerning to his parents. Sandringham Hall was on the list of the estates considered, and a personal recommendation to the Prince Consort from the prime minister Lord Palmerston, stepfather to the owner, swayed Prince Albert. Negotiations were only slightly delayed by Albert's death in December 1861—his widow declared, "His wishes – his plans – about everything are to be my law". Edward visited in February 1862, and a sale was agreed for the house and just under 8,000 acres of land, which was finalised that October. Queen Victoria only twice visited the house she had paid for. Over the course of the next forty years, and with considerable expenditure, Edward was to create a house and country estate that his friend Charles Carington called "the most comfortable in England". The price paid for Sandringham, £220,000, has been described as "exorbitant". This is questioned by Helen Walch, author of the estate's recent (2012) history, who shows the detailed analysis undertaken by the Prince Consort's advisers and suggests that the cost was reasonable. However, the house was soon found to be too small to accommodate the Prince of Wales's establishment following his marriage in March 1863 and the many guests he wished to entertain. In 1865, two years after moving in, the prince commissioned A. J. Humbert to raze the original hall and create a much larger building. Humbert was an architect favoured by the royal family—"for no good reason", according to the architectural historian Mark Girouard—and had previously undertaken work for Queen Victoria at Osborne House and at Frogmore House. The new red-brick house was complete by late 1870; the only element of the original
