I ordered kitchen 2 months ago and I hope next week we will have it, so I can see the problems.
First of all, fridge, I tried to understand where you put it in the drawing and where it can be... with this size it should be in the corner instead of the plants.
Then, the pipes, I have 4.2 m wall for the kitchen, so I had extra place for moving sink and to have a place to dry big kitchen stuff, but in this case I suppose that it should be in the corner to have a place for cooking.
Another story with the hob, as there's no ventilation for it, and all the smells will go further to the flat, and the window will need cleaning all the time.
And storage for all the foods and dishes. It would be more comfortable to use all the wall.

My mother has this kind of kitchen and when we planned the new one, we just considered the idea of using another wall and to have a free space near the window.
