Hi - first pic what is going in the middle of the shelves ? Second pic - I do think they would be better the length of the wall - not sure why they end mid way ? (sorry !!)

Hi. Re the first pic, will you have anything next to the base unit on the right to take it to the end of the ŵall? If not, I think I'd shorten the shelves so they align to the end of the base unit. Re the breakfast bar I think I'd probably Align to the centre of the bar although that could look odd with the lights, hard to tell. They are aligned centrally with the ŵall though so don't look bad

I would make the shelves over the breakfast bar the full width of the wall. The shelves each side of where the extractor and cooker are going may be a dirt collector consider having closed wall units, maybe with clear glass doors.

Still think they would look better all the way across the wall. If the main purpose of them is to have more storage to get thing off the worktops why not have longer shelves giving you more space.

I think your ideas are really coming together, it's looks great.

I'd suggest that you won't lose much light if you had longer shelves but I see what you mean re interfering with the lights.

It may well be possible to bring the outside ones inward slightly to help keep them away from the shelves if you swapped them out for longer ones. I'd say they would look better if they were bigger personally, but at the end of the day it's your space so do what you're comfortable with.

We like them, the finish matches the kitchen tops and from the photos it looks like the size and location are ok... nothing to dislike. You could make them longer, but you may not know until you start using them. If the lighting is an issue which it may not be you could try and fitting led lighting strips underneath.
