I am redoing the kitchen gutted the old one and installing new ikea units, they aren't that bad but you need to be good at jigsaw puzzles to put them together, my question / observation is that the instructions state for wall units fix to wall using suitable fixings, whould you consider suitable for a solid block work wall ? and secondly they only have two fixings at the top of the units whatever the size they are so i intend adding two more fixings in the bottom agree or not ?
