I think I don't really like this closed wardrobe; it makes the hallway look so narrow. I would recess the wall to the left so that you can at least install a cupboard in the resulting niche. Of course, that would turn the "wardrobe" into a small room, but it could then maybe serve for seasonal clothing or perhaps as a small storage room for the kitchen. Also, move the wall to the living room a bit further up, otherwise you'll squeeze yourselves in with the dining table towards the kitchen.
