Mark is a writer, the founder of HouseHistree.com, and lectures regularly at societies, festivals and clubs in both Europe and the United States. After leaving Stowe School, Mark worked for twenty years as a plumber in London. However, his real passion has always been for history, particularly the history behind houses through the characters that conjoin to create them. His special interest lies with the great American houses and their relationships with those in Europe, both socially and architecturally.
