Guest room is just a name. The extra is also important to me. To retreat. Listen to music, watch something different on TV than her, take a nap, who knows what else. Much is a matter of taste. I don’t want to impose my guest room on the questioner. If she wants a pantry, you pay the price, then there is less kitchen or hallway. It’s the same with the guest WC, which I would never put in the middle. Toilets have windows... others see it differently. Same with open kitchen. I never. She: yes. 4 floor-to-ceiling doors. Me: one is enough. She: I want 4. For the specifications list of the topic starter, the concept is good. The house works. There is always something. So: build it. Karsten
