Not for me, I find the concrete floors too harsh, the one good thing about them when they go off trend easy to cover with something else.

This is going to come down to what your space is like, light, how you use the kitchen, how does it relate to other areas of the house ie. is it open plan, so needs to complement other areas such as dining & family? Here are a few examples of backsplashes with concrete benchtops. Depends on your personal style & taste as to what appeals to you. My 1st reaction was marble, it would give interest & movement but without knowing what else you have going on in the room...

Thanks for the feedback :) regarding the two colors and mish mash I have attached what colors we are looking at. Ignore the copper tiles but the small dark grey square is the sleek concrete Caesar stone, the white is the Matt white for the cupboard and the black would be the option for the fridge side of the kitchen. Oh and the grey they are all laying on is the splash back tile (smallest sample tile they had lol) but definitely going for just the white cabinetry and sleek concrete bench. Paying deposit tomorrow so materials can be ordered :) will post a photo of kitchen when done. Once again thanks for all your feedback :)

As a concept , I love the innovation but also the consistent approach you've taken . And on a practical and visual level , I love the timber and greenery , along with the industrial feel . An awesome 'business card' !
