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.

I'd keep the island the same height- bench height is taller than a table...I think around 90cm

I have a stool on the kitchen side of the island and love it. It does men you lose a cupboard to allow for the stool , and the space between the island and kitchen bench needs to be at least 1200- mine is 1400. It is great for socialising around the bench. It seems to be where we all gather- I can sit and join in, organise food, drinks easily. It works so well 2 of my friends have incorporated the idea into their kitchens.

This is a houzz picture with similar location of fridge and island.
