Hi elinitha, this will be the laminex impression decor 'weathered oak' which has both visual (white ingrained) and tactile texture. It will be used horizontally in a beach house. This colour I would recommend your timber feature also, as it looks natural, as in no staining or lacquered aesthetic, and as a finished product, no maintenance, fading and is more durable than a genuine timber product.

I would clad it in horizontal wide timber flooring planks. Myself I'd go a grey, weathered timber like an oak, the engineered flooring can be bout in packs, so a single pack would create a feature inexpenssively. It will provide the oppotunity to introduce timber details in furnishings or kitchen accessories. Natural timber softens modern interiors, relaxes and adds character to traditional looks like provincial or hamptons styles. The wide plank will enhance the flow as a walk through, but still provide an intersting visual texture to the adjoining lounge area.

I've noticed a recent trend of the vertical color on the island matching the vertical color on the splashback. Liking that trend. So I would say go with the turquoise glass splash back color. Deepen it a little so the hue is closer to that of the floor. Cant tell from pic whether island cupboards are the same color as cupboards above the splashback. If they are, all the better. That then brings the turquoise/white combo forward into the room and gives some unity.

I think you should lay the floor first as I'm almost certain it will change your benchtop choice. There will be very little contrast in that space once you install a washed oak floor. I understand the reaction to the dislike of the current benchtop to choose a really pale one. But you may well decide on more definition than those very pale choices provide. If I look at all the modern white kitchens they typically have a large dark contrast area in the room to bring out definition.
