I have a corner unit, pretty large, which a friend has had her eye on for some time. Her partner came over to collect it this evening and there is no way it is going through my doors! Must have grown in the last eight years as it came in without any doors being removed, but I don't think it would go even then! My ingenious friend is coming tomorrow and he knows he has a challenge and a puzzle rolled into one. Will let you know if he solves the riddle!
