These Are The 14 Most Challenging LEGO Sets To Build

LEGO has been around for more than 80 years, and in that time, there have been thousands of building sets released. From Scooby Doo to Star Wars, their sets have millions of tiny little pieces to assemble.

While building LEGO sets may seem easy enough, especially with the instructions they provide in each box, the labor it takes to build some of their sets can take hours – even days.

Here are what we consider to be the most challenging LEGO sets to build. When defining what is the most “challenging,” we took what the set is, how many pieces it has and its level of difficulty into consideration.

1. Star Wars Millennium Falcon (5,195 pieces)

This themed set is one of the biggest LEGO model ever made, containing over 5,000 pieces. It comes with a retractable boarding ramp, a removable cockpit top and rotating guns.

6. Star Wars Sandcrawler (3,296 pieces)

7. Eiffel Tower (3,428 pieces)

Create the iconic French landmark that when completed, stands over 4 feet tall. With its pieces being almost all grey, this proves to be a challenging set to build.

8. Star Wars Death Star (3,803 pieces)

Since this set is an open circle, it is different from your typical LEGO models, making it more difficult to build. With all of the mini figures the set contains, you can build several scenes from the iconic movie all on one model.

9. Star Wars Death Star II (3,417 pieces)

This set can be built as a sequel to the original Death Star set. It’s over 2 feet high and comes with a display stand.

10. Sydney Opera House (2,989 pieces)

This Australian landmark might not have as many pieces as the rest of the sets on this list, but with the pieces mainly only being two colors, it can get complicated.

11. Statue of Liberty (2,882 pieces)

Just like the last set, this one again does not have as many pieces, but it also has less colors to work with. That being said, this is considered a very difficult model to complete.

12. MARVEL Shield Helicarrier (2,996 pieces)

This detailed LEGO set contains mini figures such as Captain America and Black Widow, two runways and three fighter jets. With all of the pieces that come with this set, it may be difficult to keep everything in order while building.

13. Star Wars Motorized Walking AT-AT (1,137 pieces)

What makes this set different from all of the other Star Wars LEGO is that it actually can walk – if it’s built right. With thousands of less pieces than the others, the main challenge with this model doesn’t come with building it, but instead in getting it to function.

14. Star Wars Imperial Shuttle (2,503 pieces)

This shuttle’s pieces are mostly all shades of white, providing an extra challenge to builders. It is another moving model once completed, with rotating wings.
