How about getting her a DIY dollhouse kit? That way, she can build and customize it exactly to her liking. You can also make it extra special by setting up a special space for her to display the finished product. Another idea is to get her a rare or vintage dollhouse that she doesn't already have in her collection. You can search for these online or at antique stores. Additionally, you could surprise her with a subscription to a dollhouse magazine or take her to a dollhouse exhibit or convention.
Or you can get her a star map with the date when she was born.
