cons: "One architect told me that someday I would end up with a suicide on my conscience because of my bullying. Another accused me of drastically changing his children's future by making him redundant as an architect. For all these reasons it's important to be able to communicate in the open."

pros: "Other people just think it's fantastic. The child of one owner jumped up and down in excitement when we rang and asked for permission to use their house in our book: 'I knew you'd come, at last!'"
