BEFORE:

blue all in the doors.. making my tiny galley kitchen dark.

Looks like Now:

Husband is diy as he goes. Either way he going have to prep the wall. Didn't know how make it look right.

repair the wall/ paint it same wall color and set canisters there.I wouldnt mess w the blue any more. However you achieved the "faux" brick look in center cabinet panels.....that's fine...get some hardware now and I'd be done. Its not worth more work. the counters are in pretty good shape/ they work w floor and cabinets so you're good [ is my opinion/ thinking blue and beige tones work]

here are nice canisters for your tones/ runner on floor as well.

Things will never look right there with your bumpy knock-down plaster finish unless you do the whole wall. I don't think people are looking close and seeing that your walls are not smooth. He's going to be creating a mess if he starts sanding outside the bounds of that shape.

I suggest you have a piece of mirror cut and stick it right over the rough area. My poor photoshop may look like it takes you right back to where you started but the mirror actually will reflect light (especially under cab lights) and brighten that corner day and night not to mention give the illusion of depth.

just clean up and sand the wall, Paint.

it looks too boxed in with the laminant on the wall.

I dont think you need a side backsplash itll look weird with the blue. Just fix the wall and add something tall if you'd like on that corner

This is the old counter, correct?

What color is the new laminate?

Hold on this what going

the side along with new countertop.

Hope this makes sense. Yes its hard to paint since no telling how did the textured wall.. that is why thinking sheet of stainless so add some magnetic hooks and use it to hold baking items or hand towels. Yes my husband already pulled off some more of the blue laminate.

I would simply paint it the same colour as the wall.

Note: You can cut out the piece that's damaged and replace with a square piece of gyproc then simply fill the joints and sand...

No side splash is needed. On such a small area you should be able to get the texture close enough.

Wasn't initial sure if that was what this was all about... the wall texture on the side. I like my mirror idea better than the stainless sheet with hooks. A rectangle of mirror with a stainless edge frame would look neat and tidy. If you really need hooks use suction cups.

The cabinet door panels could be easily …affordably replaced with glass ..for a much more open feel…the horizontal wood strips clash with the frame design…even if painted the same color….you could use frosted glass if the cabinets will be too cluttered
