About the design: at first glance, I liked the approach. But the kitchen becomes really dark, and when guests are there, you can no longer easily get into the kitchen niche. It won’t be easy to work there with two people either. Where exactly are the refrigerator and the oven? I find the workflow for quite a few daily tasks here rather complicated and not smooth. Not even remotely smooth. The stairs look very steep or short to me. Basically, there is a complete lack of storage space. The scarce 7 sqm are enough for one shelf with tools, light bulbs, and cleaning supplies. I see no space for drying easy-care laundry, no beverage crates, decorative stuff, mop bucket, yellow sack, and ironing board. ([Alles Platzhalter für so vieles]) The questionnaire unfortunately hasn’t been filled out regarding number of people and preferences, needs. You see the current state, but don’t know the desired state. Since everything is pinned in posts, I’ll save myself links and further explanations.
