:
Thanks for your explanation. I don't think putting the oven instead of the fridge in the corner is a bad idea; otherwise, the planned kitchen layout is similar to your suggestion, except that we have one or two fewer wall cabinets. But generally, the arrangement with sink and cooktop is the same.
The idea of the partition wall is good, but honestly, I wouldn't like it visually. I also don't think you can fit two large tall cabinets in the corner if I want to place the door in the middle; basically, there would be only about 1.11m left on the right. If I were to calculate an oven with about 50-60cm, in my opinion only, for example, a pull-out pantry cabinet would fit here.
I wouldn't even mind that at all. However, I am currently wondering whether, given the rather small kitchen, it is so important that the fridge is in close proximity to the fridge.
One thing I didn't understand, what exactly did you mean by the sofa/reading corner?!?
