Concrete bench tops and decorative concrete pieces are a good idea if you like the solid look. I certainly would not recommend asking a general concreter about a concrete bench for your kitchen. Normally the bad rap that concrete bench tops get are when they are manufactured like a driveway or footpath. Kitchen bench tops require different characteristics. They should be constructed dense (to help prevent staining), flexible (to prevent cracking), lightweight (so can be manufactured off-site). With the materials that are available now, concrete can have all these characteristics. Sealing is another topic for the professionals. There are three different methods of sealing concrete. Penetrating, Topical, or Reactive. Sometimes all three are used to seal a concrete kitchen bench. This is because the way a kitchen bench is used is different to a floor. You are not only trying to prevent staining, you are trying to prevent etching that could occur with acidic foods. There are companies around that specialise in concrete bench tops for kitchens. Try them you may be surprised at the options available for "concrete" bench tops.

I think that would look great with floorboards in a classic walnut colour, that would definitely look great with the light cabinets. If you want an idea of how it might look with the end finishes, you can type this into google and they should be able to show you a few.

I would not use a white stone, such as a Carrera Marble in any kitchen, no matter what the colour of the cabinetwork due to the porosity and risk of staining. Better to use a reconstituted stone benchtop which is manufactured to look like stone, such as Caeserstone, or one of its competitors. If you have the budget look at Dekton for whitish stone-like benchtops. As far as the monochomatic scheme it can look very smart, but will depend on the amount of natural light and artificial light in the room. Perhaps consider doing the overheads in white, and paying special attention to your choice of splashback. You may also want to consider how long you will live in your home, as black kitchens are very much on trend, and in ten years time they will have dated and look very 2018.

sorry, not good with technology. Nothing has been done yet, just wondered what colour would go with white and terracotta. Thanks.
