I agree with Red80 re furniture layout. There are lots of good things in this room, I just personally find the cushions and blinds clash with the chandelier and wallpaper. I would swap the 2 geometric cushions for softer patterns in lighter grey/white/duck egg. I'd get something with different textures as the cushions fabrics look the same atm? Add accessories to your coffee table, maybe just a pile of books, a vase of flowers, and an "ornament" in wood/ceramic/pewter etc again for texture. When budget allows swap the blinds for Roman blinds. Try blinds 2 go or Tuiss which is their sister company if you're in the UK. I can't remember the exact price but I got pure silk Roman blinds for 2 really large windows for c£450 which sounds a bargain to me although not yet up:) I agree the mirror is a little high. If you can, without leaving a hole on show in the wallpaper, I'd lower it as long as it doesn't reflect the tv! I'm not sure the pics to the left of the window work as they're obscured by the curtains. Perhaps also a taller vase/pot in the blue for the tv cabinet to detract from the tv a little more? Alternatively you could change the wallpaper and the mirror to give the room a contemporary rather than classical feel

A much more functional layout can be achieved in the existing room by flipping the existing hob and fridge freezer. It looks like you are currently losing a good 30cm or so of potential counter and cabinetry space next to the doorway, and it would give you a longer counter run between sink and hob. I would also add a long bank of shallow low cabinetry alongside the wall between the 2 doorways, which would give you quite a lot of additional storage space without interfering with the walkway or sight lines. Plus the narrow ledge there could help keep clutter off your work surfaces. In terms of dining space, you could lose your unloved peninsula and then add a small table and chairs. You would have to squeeze in the 60cm oven into the main work area, but 30cm would be gained by the fridge move, and another 20cm could be gained by swapping to a 60cm sink cabinet. (I assume it’s 80cm right now.).

Sorry, it's a screenshot of a video! Yes, the tiles are the browny colour. They look a lot darker now they are against the white and yellow!

There are virtually no true dull orange terracotta colours on the market as yet, surprising as Terracotta is all over instagram at the moment. You could go to Valspar and get one mixed.
