yep, stunning. I been drawing something similar for a while and it's awesome to see your ab fab results after your OP. I got interested in some ikea solid timber benchtops, not nearly as nice as yours, and thought I'd combo them with black cabinets, white stone and white walls (just a "what if" design). so I totally love your kitchen. it's great how well the tiles look now compared to when you first posted, they really excite me! and the lightshades against the black wall. and what's that dining area I see? that smoked glass table top with timber trestles and black chairs and that black and white rug? where you get those?! I want to see more! congratulations, it's hard not to gush! big ups to Mldesign too.

It's a bit difficult to tell with the range hood light reflection on the wall, but could you add some kind of small bench top cabinet or perhaps a floating wall cabinet between the cooktop and the sink to put/hide your Nespresso and other appliances, plus the powerpoint? The raised bar/mess barrier will also help.

I've noticed a recent trend of the vertical color on the island matching the vertical color on the splashback. Liking that trend. So I would say go with the turquoise glass splash back color. Deepen it a little so the hue is closer to that of the floor. Cant tell from pic whether island cupboards are the same color as cupboards above the splashback. If they are, all the better. That then brings the turquoise/white combo forward into the room and gives some unity.

I have a 4 and 6 year old and they do grow through that stage quickly. We used pool noodles and cut off pieces as needed. Then split them up one side to slip onto sharp corners and to keep doors open. Very cheap and customisable.
