Favorite set so far!!!

I had so much fun with this set. The modular buildings make the whole experience so much better. I have anxiety, and doing legos help me to relax, but I always feel that rush when finishing so I can see the buildings complete. This set was so enjoyable because you feel like you have four different sets that come together in the end. There is so much detail that makes you feel nostalgic. It also turns into a beautiful decoration piece when it is done.

Love this!

I really love these kinds of builds where they are modular and can be stored in multiple configurations! I also really really hope that they do another build like this for the other side of the alley and include some of the other iconic shops from Harry Potter since we are missing things like the Leaky Cauldron, Madam Malkins, an Apothecary/Potions Supply story, and the Pet Store. My next set to get is Gringotts and I'm so excited for that to go with this set!
