Hello and welcome
That's a big name for such a little one
I agree with Cypher about the cage. When I first brought my hammy home he had a cage with tubes and it quickly caused issues. He would block them up and then started chewing on them so I ended up replacing the cage with something much bigger without tubes.
Having the house on the bottom level means you can add thicker layers of substrate for them to burrow into as they sometimes like to scoop out a nest area and then cover themselves up with shredded toilet paper and bedding like a blanket. It insulates well this way and having no base on the house keeps things ventilated so it doesn't get damp. They also tend to store their food underneath the nest so having those extra layers of bedding gives them somewhere to bury it.
