    This modular build was really good and focusing. It’s like you are getting three modular buildings in one package. If you are into modular building, I suggest you get this before the price goes up since it’s a now hard to find item.

    Reviewed in the United States on February 3, 2023
    I love the way this lego set looks. It has so many intricate details. It is just amazing when looking at it. It is definitely a more advanced build. You would have to open up several bags per section and dig through a giant pile of pieces. There was a lot of pieces to put together on many of the steps. This would be a perfect project to keep a whole family busy because it would give each member plenty of pieces to put together.

    Reviewed in the United States on November 23, 2023
    This set was a great challenge. With a little over 4,000 pieces I underestimated how detailed this build would be. After 14ish hours put in it’s worth the challenge.

    Would highly recommend to Lego Lovers (added the Bookstore once done & it really puts it all together).

    Included pictures of some lil details that were added in :)
