Nice set, long delivery time.
Nice set, undamaged packaging. However, the delivery took a week longer than expected. It seemed to be stuck with the carrier. Nevertheless, I was adequately helped when I contacted the seller about this.

This set was an absolute dream to build. The detail within each modular building is great and it really feels like you creating something unique with each section. There were a couple of missing pieces (3 1x1 bricks) however I manged to be creative with some studs and make these look better for a wall post than the normal bricks would have been so it wasn't an issue for me. As someone who is autistic and struggles with following 2D instructions I do with the digital instructions were available for this as it is a little tricky understanding some of the build instructions. However this is a me issue and not a LEGO issue. I really enjoyed building the set and I did one section each day to make it more fun. As for the price, I do understand some peoples concerns with with being just under £400 however splitting it into 4 sets and the detail I do think that it is reasonably priced for what you get and the enjoyment. I also like the fact that it is clearly set up for expansion with being able to attach Gringotts (I'm yet to purchase( and also a Knockturn Alley should they release that at some point) This set was an absolute dream to build.
