Love seeing all your amazing display setups. I wish I had space to be able to display all my LEGO Harry Potter sets. Unfortunately living in a rather small house with family of 5 plus 2 cats means space is at a premium. I do however plan to clear out my loft, currently full of star wars, Ghostbusters, Hornby, corgi and video game collections that I'm selling (partly to pay for more Harry Potter LEGO sets). I'd love to have a huge table up there to build a custom Wizarding World setup, probably half vintage sets (2001-2012) and the other half with all the current sets displayed.
I just purchased the Burrow, Knockturn Alley and Shrieking shack sets, only about 10 sets left to complete the collection (at least until the 2020 sets are available)
