The builders started to put up the partition wall between the master bedroom and the en-suites. It was in the wrong place. The lovely beam that we wanted to be in the bedroom was going to be above a plasterboard ceiling in the bathroom, completely hidden from view. I phoned Didier to ask for an explanation and he said it was because the bathroom pipes were in the wrong place (which we had asked to be moved several times previously...). He sorted it out and they will be moving the pipes (and partially completed wall). Job done.
