The whole of Streatley used to be owned by the Morrell family of brewers from Oxford, whose resistance to change enabled the village to withstand the railway line and extra houses that went to Goring. The watermill was originally owned by the nuns of Goring. In later years it was used to drive a generator to provide electricity for the estate. However, it burned down in 1926 and was not rebuilt. On the death of Emily Morrell, in 1938, the estate was sold, and the manor house and some other houses in the village became part of the Royal Veterinary College, which had moved out of London during the Blitz. The college left in 1958.
