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.

Are these the only options you want? There are so many beautiful reconstituted stone options so nothing is really black or white any more. Do you have a picture of your space and the rooms that open to it?

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.

it should be quite easy to change the size of the base cabinets to create knee space..usually about 30cms deep...i would expect a deeper counter would be the easiest (but a bigger piece of stone may be challenging and you might have to consider an alternative counter material) so consult a kitchen cabinet maker for specific advice and quotes and they should be able to reuse the existing sink, taps, doors and some or all of the cabinets for two options : a new smaller base cabinet or a deeper counter so ask for quotes on both options but first line up some chairs to decide if the bigger counter is comfortable in your room
