You have a few options here to make some big improvements. 1. You could remove the wall that has the doorway in it. You may need to relocate your stove and range hood or you could have a range hood that you can see "in the round". You would lose those upper cupboards though. or 2. You could remove the other wall to the side of the doorway. This would then mean that your kitchen would open up to the living area but you would lose some full height cupboard space along that side. I also noticed that your TV is located in that corner. Do you need it there or can you relocate it to free up that wall? or 3. Perhaps you could flip your kitchen so that the breakfast bar is near the dining table rather than at the other end. The stove and range hood could then go at the end where the current breakfast bar is as well as upper storage cupboards. Having the kitchen open onto the dining area could be very nice if that's what you are after. It depends on the rest of the living area, too, whether you would like to open it up totally as well. There is a lot to play with here and it can be a lot of fun. I wish you the best of luck with your renovations.

How about a water feature? Inspiration.

The mirrored wall certainly gives you a 'wow' factor and the floor is stunning. I wouldn't do a textured wall paper or metallic, I think you'd end up with too much going on in a small space. If anything I would perhaps paint the white wall in a very light grey to pick up the grout in the floor tiles.

The second look like they are designed for stairwells so I'd be a bit wary about using them up higher as the light might be a bit "spotlight" and not diffuse enough. I think both styles work with your house design
