Prince Charles is in big trouble with residents of Daglingworth in Gloucestershire, said to be one of the prettiest villages in England, if a story in the Mail on Sunday is to be believed.The Duchy of Cornwall has moved an unsightly crinkly-tin barn, three times the size of a tennis court, from its existing home next to a nice granary, and plonked it down in the middle of the village to general disgust.The reason? Sale of the granary for £800,000. Not for use as a granary, you understand, but as a nice des res for a purchaser who is spending another £800,000 doing it up. This would not be so bad if it were not for the fact that the prince has made a point of objecting to conversions of rural buildings for residential use. No doubt there are compelling differences about this particular case.
