Task: Question Answering
Input (English): Passage: Within a decade, the house was again found to be too small, and in 1883 a new extension, the Bachelors' Wing, was constructed to the designs of a Norfolk architect, Colonel R. W. Edis. Edis also built a new billiard room and converted the old conservatory into a bowling alley. The Prince of Wales had been impressed by one he had seen at Trentham Hall, and the alley at Sandringham was modelled on an example from Rumpelheim, Germany. In 1891, during preparations for the Prince of Wales's fiftieth birthday, a serious fire broke out when maids lit all the fires in the second-floor bedrooms to warm them in advance of the Prince's arrival. Edis was recalled to undertake rebuilding and further construction. As he had with the Bachelors' Wing, Edis tried to harmonise these additions with Humbert's house by following the original Jacobethan style, and by using matching brickwork and Ketton stone.The house was up to date in its facilities, the modern kitchens and lighting running on gas from the estate's own plant and water being supplied from the Appleton Water Tower, constructed at the highest point on the estate. The tower was designed in an Italianate style by Robert Rawlinson, and Alexandra laid the foundation stone in 1877. The Prince's efforts as a country gentleman were approved by the press of the day; a contemporary newspaper expressed a wish to "Sandringhamize Marlborough House – as a landlord, agriculturist and country gentleman, the Prince sets an example which might be followed with advantage".The royal couple's developments at Sandringham were not confined to the house; over the course of their occupation, the wider estate was also transformed. Ornamental and kitchen gardens were established, employing over 100 gardeners at their peak. Many estate buildings were constructed, including cottages for staff, kennels, a school, a rectory and a staff clubhouse, the Babingley. Edward also made Sandringham one of the best sporting estates in England to provide a setting for the elaborate weekend shooting parties that became Sandringham's defining rationale. To increase the amount of daylight available during the shooting season, which ran from October to February, the Prince introduced the tradition of Sandringham Time, whereby all the clocks on the estate were set half an hour ahead of GMT. This tradition was maintained until 1936. Edward's entertaining was legendary, and the scale of the slaughter of game birds, predominantly pheasants and partridges, was colossal. The meticulously maintained game books recorded annual bags of between 6,000 and 8,000 birds in the 1870s, rising to bags of over 20,000 a year by 1900. The game larder, constructed for the storage of the carcasses, was inspired by that at Holkham Hall and was the largest in Europe.
