This morning I went on a visit to the Wentworth Estate in Virginia Water.   It was a new experience for me because I had no idea that such massive classical houses were still being constructed, although, having now done a bit of research on it, I realise that some of them are being designed by Julian Bicknell and some by my nephew George.   The estate itself was laid out in the 1920s for captains of industry  and stockbrokers to enjoy a semi- country life of golf within easy reach of London and the impresario behind the scheme was a builder-cum-developer called Walter Tarrant who had begun by building arts-and-crafts houses in St. George’s Hill, Weybridge.
