The shelf is new, so that is why it is completely empty. I also had to buy a new table for the finished model since the footprint is so large. In total, the 25,000 bricks were not too expensive. I managed to buy 2 of the original hogwarts sets at about 35% off, and then I bricklinked the rest. Maybe somewhere between USD 1,500-1,700 including shipping, VAT and import tax. Glad that most pieces were inexpensive because they Are mostly 1x1. The worst part of the build was the 25-30 hours I spent on bricklink tracking down and ordering parts while updating the enormous parts list.
I had to recreate the «Snape kills Dumbledore» moment! Mostly because it is so memorable due to the online spoiler hysteria. I have some more photos I will post when I am back home.
