I think it will make my project even more clear if I also write a few words as a small presentation:
KITCHEN
I know you said you would prefer a fridge D 70 x L 70 cm but I like to suggest a fridge / freezer L60 x D 60 and H180 that you can buy from Miele or Candy for example as I used the space to put a tall unit L30 cm that you can order with a pull out mechanism and this way you will have a much needed storage space for food items that don't need to be refrigerated.
I have placed both a convection oven and a microwave oven in a tall unit. This way I could fit into the kitchen composition also an integrated dishwasher and a washing machine, but if you think you don't need them in the kitchen, you can easily order your kitchen with normal units on that space.
I also placed in your kitchen a sit on top roll top near the bar, where you can put all the kitchen appliances (toaster, mixer, etc,) but also the glasses and bottles for the bar.
For the kitchen I used a German supplier named Leicht - I'm sure you must also have them in Turkey if you want - the quality is very good for the money spent. The model I used is TOPOS.
The worktop in the kitchen would be nice in dark red CORIAN
LIVING ROOM AND DINING ROOM
For the living room I used a wall system, the coffee table and the dining table from NOVAMOBILI - Italy
The bar chairs and the dining chairs and the sofas are a very well known model produced by many. I had in mind all these to be in black leather.
LIGHTING
For lighting in the kitchen I suggested a white neon light on the center of the ceiling, 2 spots with white light under the wall units - left and right to the hood, and 2 spots with white light on a beam I have positioned above the bar.
Above the dining area I have placed a dark red sphere to match the color of the worktop.
In the living room I have provided spots with white light on some false beams placed on the ceiling to match the style of the coffee table and the wall system.
