Creative ideas needed for dollhouse

So my oldest, 6yo, is going to have a Dollhouse for her birthday. However, usually when she plays she doesn't want her stuff to be touched (especially if she takes time to build it). Her little sister ,19mo, will be interested and touch it for sure. We have a small house and don't have many rooms to accommodate so I was wondering if you have any tips on where I can put the house so she can play in peace but be with us at the same time? Sorry if it sound stupid but I'm trying to find a solution 😅😅
