Fittingly update. Wonky floor and walls do not help, but it's going in. It physically could not have been any wider and still have even units. The two on the left only just fit that alcove.
A 7 out of 10. Good instructions and well thought out fixings (all depending on the design being right, but they are really helpful with that part). I had to get the neighbour round to help me lift the three big/deep units up on top as it was just too much for me to do solo.
