Soop, No, he was a retired business man and they lived on a leafy estate of very large pre-war stockbroker's tudor houses. He and his wife's plan caused ructions among others living on the estate and the result looked like a small laboratory block for a start-up pharmaceutical company - and it looked like that inside as well.
Are you thinking of the Hof House built by an architect turned painter and his wife? That I really liked, apart from anything else they filled the house with their belongs, his paintings etc that were all vivid and colourful. So many of these big white houses are completely unfurnished, no pictures, no ornaments, no belongings at all, just large white or black settees. Characterless houses for characterless people.
