So, the chaos ended.
Actually it ended last week.
Of course after that we had to put everything back in the cupboards, etc. We took the opportunity to undertake a further cull (having chucked lots of stuff away when we emptied everything before the installation began). I really didn’t know we had that many mugs.
Since then I’ve tiled the floor with some nice Italian ceramic tiles – I have to say I’m jolly pleased with the result.
