I wonder if any Estate Agents or Interior Designers ever use Playmobil to aid their work? Fittign furniture into a room, at least in the UK, can be quite a chore.
My house is a 1860s Victorian mid-terrace, and as such we have a very narrow staircase and doors, while the house is spread over three floors. Almost all the furniture has been assembled in situ, and if we ever want to remove it we'd have to take it to bits again - and then we'd lose the plans!
