Home layout

I’ve recently decided to renovate my old house from 2021. I have finished renovating 3 bedrooms, 3 bathrooms, and that’s about it. I still have to renovate the kitchen and the living room, along with the hallway upstairs and possibly the dining room. In the upstairs, I have 2 empty rooms which im not sure about. I don’t know what to use them for and I need some ideas. Thank you to anyone who helps me.
