I didn’t think this would be possible, but I searched “white wash slate” on Pinterest and there were a few posts 🤔. Would be interested to see how it turns out. Good luck. https://www.pinterest.com.au/pin/251779435401045832/

How funny. I just renovated (on a budget) my small kitchen and added exactly the slate look in tiles you have, though they are in fact porcelain. And I placed them throughout the house for continuity. The tiler asked if I was after a retro hippy look but it doesn't look like that at all. My cupboards were the same colour as yours and I utilised the bones of the kitchen and had the doors and Benchtops changed only. I also have plenty of light in the kitchen but chose white doors and as I was on a budget I chose granite look Benchtops, they are very serviceable and it looks great. The blue backsplash was the colour lift and here you could choose any colour to your liking. Basically the kitchen ended up with white cupboards and appliances other than cooktop, with the stainless cooktop and coloured splash back being the focal point. The paint colour are: whisper white walls, integra splashback, white ceiling and for increased contrast I used the same white above the splashback on the rear wall. I would consider painting out the brick but leaving the texture.

We would recommend two choices - matching your wall colour with a tone of the slate and your roof or you could have the slate removed as well a plasterer to fix and repair the patches then you are not limited by colour selection to match in the slate. A possible use for the slate if you choose to leave it there would be a floating seat (painted black like your roof) just below the slate - use the slate as a seat back or continue the slate up and create an outdoor BBQ area with the slate as a splash back for the BBQ. You could also install a floating bench (but check the weight bearing possiblities of the wall). A great landscape designer &/or builder could help you with a concept plan - good luck! The yard looks like a great space - BBD

White-matte cabinets (flat panel, not shaker) and white bench (or maybe epoxy sealed marine ply??...siriuskey can tell you about that), mirror splash. Love the ceilings. I personally would go for a modern, stream-line, no handles, integrated appliances look. This space has real potential to be very cool, even with the slate. It doesn't need any more more texture or darkness. This is a nice kitchen, you should be able to sell it on ebay.
