It seemed fairly straightforward to make the floor all one level upstairs. But once the clever carpenters started doing the new joists, they found that the existing floor was actually on a slope with a total drop of 14mm. Ching ching – another Variation as they built up the difference. Finally they have put down some boards at the new level. I’ll get another shot soon which shows this new space off better. Suffice to say, it is vast. I’m going to need a new vacuum cleaner.
