I already thank you for the kind answers. There isn’t much enthusiasm for the office, which is okay. However, the office in my old apartment was also about that size and I felt quite comfortable in it. I only want to equip the wardrobe with a clothes rail. But you could certainly open the door to the hallway. I am such a fanatic about tidiness and therefore prefer to keep my son’s mess and dirty shoes behind a door. There’s also room for the sports bag there.
I would like the terrace to be by the kitchen and in front of the utility room. I might add a pergola there. I don’t like it when the nice big windows are blocked from the outside with furniture. I’d rather look out onto the field and enjoy the view.
By the way, I have only planned a “normal” window in the living room. I think it’s silly to block floor-to-ceiling windows. Besides, the living room is a cozy zone and therefore should be comfortable and doesn’t need to be a glass palace. Who realistically looks into the garden in the evening while watching TV?
