I would do a glass splash back [ this can be painted in your color choice to suit the decor ] - taking from the bench top up to the bottom of the range-hood on the wall of the stove. The window is beautiful and I would give anything to have them in my kitchen. I would probably paint OR stain and apply marine grade vanish to the would so that any moisture would not be able to ruin the wood. I would also put herbs or flowers there. Could it be made into a servery for outside maybe ???

The first thing I require each of my clients to do before even starting the design layout is to choose their appliances. Your kitchen designer will need the manufacturer's specifications to know what size to make the cabinets to accommodate them. Be aware that there is required distances needed around and island, typically 36" up to 48" depending on placements of appliances. This will dictate the size and shape of the island. Clean lines, simplicity, innovative materials like glass countertops, exotic woods or Italian veneer slab doors, flip or lift up doors can add unexpected touches to a modern/ contemporary space. Here are some photos of one of my favorite Euro Modern kitchen I did for one of my clients not long ago.

i think that a mini-subway tile in a carrera marble and gray colored grout could be stunning in here. subway shaped tiles are both modern and classic and will never go out of style...your options are really limitless. this space appears to be open to another, if you add color to the kitchen, be sure that it makes sense with the adjacent room. this space is going to be great!! already gorgeous! keep us posted!

Will you be keeping the cork tiles on the floor? If so, make the countertop/bench top a similar color. They are both horizontal surfaces. Choose a color you like that has a bit of yellow in the base (ex: tomato red instead of crimson, or lime green rather than mint green).
