Is the wood/shiplap wall straight ahead. ( not in the kitchen) staying that color? I’d match it to that light wood tone.
I wouldn’t overdo the shelving. Personally would prefer to have less even if part of or a whole wall is left without uppers or shelving and just tile.
What’s your backsplash plan. ( you shouldn’t have it picked out and finalized yet but I’m asking what are you thinking? Slab? Tile? Color? Shape? )
Very pretty space btw:)

IMO open shelving in a kitchen is just one more thing to constantly clean and with no real advantage I also would need to see the hood design but IMO wood hoods are also a grease and dust catcher that is more hassle than I want . A simple stainless hood is IMO a much better choice and you do realize that those lights will only light the top shelf so pretty useless without pot lights . Make sure that lighting is LED bulbs in 4000K all over too

I will more than likely do some sort of white back splash. I like the idea of being able to change little things and use color with decor. And you can see the white washed pine tongue and groove from the kitchen.

Something similar maybe for range hood

If the sink is going in to the right of where the DW is marked, you can't do shelves all the way across, but you'd likely want them between the sink cab and fridge, right? That counter appears to be where you will be doing the bulk of your prep work, so that's where you'll want things like cutting boards, flour canisters, etc. Where do you plan to store most of your dishes?

Wrong wall lights for this situation. I'm assuming you would like all the shelves lit and not just the top shelf.

Place the first shelf 18-20" above the countertop as you would a kitchen cabinet and then figure out the spacing for the next shelf taking into consideration what you would like to store on the shelf.

Thank you. The lights that are on the walls now are temporary.

I agree with you on using color in Decor. Love that too. I like that the hood options are open to a cabinet material ‘finish’ however I think if you can go bigger. Taller. It would fill the space nicely.

Again, like the idea of a white backsplash. And as I said I’d do less shelving and more visual tiling. My personal opinion and preference...
