I can never quite understand how these teams of experts can turn up and redecorate 3 rooms in someone's house without their prior knowledge. Surely they must have to get written consent from the home owner? It's obvious that they must have room dimensions in order to get things that fit, and I can see that friends or family members could sneek around and get those - but even though I'd love to have my house decorated by someone else I'd want a say in how it was done and what got thrown away. How do you think they do it? And do you reckon the home owners know beforehand?
