Can't miss what you don't use!Haha you are right, but that shows that we never used them all actuall;y, I thought it was 5. But it was seven, the thing is though we only ever used 2-3 at a time.
When you say side-panels, do you mean colour-coded with the cupboard doors?As for the space at the side of the extractor, we wanted the super wide drawers. 900mm wide. We opted for the 600mm hob and extractor, we could have move the wall cupboard in more to reduce the space to extactor, however we wanted the wall cupboards lines to match the lines on the base cupboards, as we prefer this look. There is no right or wrong way, just personal preference really. I do still have the side panels to affix to the wall units either side of the extractor and also the splash back on the wall too.
But you can see the line up of the units in the below pics. Considering this is the first time I've ever undertaken a big project like this myself, I'm extremely happy with the results.
Good job on the lining-up, that pleases me greatly.
