I would reconsider the widths of the room doors once again. Your WC door only has a rough construction dimension of 63.5 cm, which is like an airplane toilet. A children's room door is also only 76 cm, which I also find too small for a room door. Is such a small wardrobe enough for you in the bedroom? Overall, the bungalow is too small for 4 people, maybe it’s okay for 3.
Best regards
