10 of the Hardest LEGO Sets to Build

10 of the Hardest LEGO Sets to Build

LEGOs have been a childhood favourite for decades. Who would have thought that blocks made of plastic would take the world by storm?

LEGO has been conquering the toy scenes for years and it’s apparent that it isn’t made for mere child’s play. Kidults, or adults with a continued fascination for children’s toys and media, have been actively building and collecting intricate LEGO pieces to this day.

Let’s dive into the world of LEGO and see which ones are the hardest to build:

Titanic (10294)

Sitting at the top of the list is the Titanic, the famed sunken ship that has made its way into pop culture in the 90s because of James Cameron’s titular film named The Titanic.

If you’re a history buff, this LEGO set will surely catch your fancy!

Made with a whopping 9090 pieces, this set is sure to test your patience and determination. It is a huge set to finish but your hard work will pay off once it is done. This is a set worth displaying in your home.

Colosseum (10276)

The legendary colosseum in Rome is in ruins as it had been around for centuries, but you don’t have to look any further if you want to step into the past and see it in its full glory.

All you have to do is build one!

The colosseum set comes in second with 9036 pieces and it’s one of the hardest sets to build – not because of the sheer number of small LEGO pieces it comes with, but because building it can feel extremely repetitive and might bore you.

‘Star Wars’ Ultimate Millennium Falcon (75192)

Next on the list is a Star Wars favourite - the Millennium Falcon is made of more than 7500 pieces.

While the set is recommended for ages 16 and up, it is definitely worth the hype. 7 minifigures are included from the Star Wars franchise, as well as a bordering ramp that can be lowered and a cannon that can blast the power for when you want to play with the set – which is, let’s be frank, a Star Wars fanatic would do to relive action-packed moments from the films.


Land Rover Defender (42110)

The Land Rover Defender is one of the hardest LEGO sets to build and many avid collectors have found it frustrating to complete the set. A particularly hard part is combining the chassis, which required two assemblies to be put together.

Your hard work will pay off once you're done, of course, as the Land Rover Defender will be a thing of beauty once it’s all set up.

Taj Mahal (21056)

The legendary Taj Mahal (the actual one in India) surrounds itself in prestige and magnificence as a symbol of one man’s love for his wife. The landmark is viewed by millions of people every year, and makes it a “must-visit” for tourists to the South Asian country.

But the LEGO set is a whole different story, one that makes collectors want to grab one and build it ASAP!

With a whopping 5923 pieces, the Taj Mahal also packs a punch even for the most enthusiastic LEGO aficionado. Many have claimed that some parts don’t align very well with each other even when the set is complete; however, you’ll be patting yourself on the back once it’s all done and dusted and you can proudly display your very own Taj Mahal in your home.

Bugatti Chiron (42083)

Car enthusiasts unite! The LEGO set is one for the books if your hobbies consist of cards and LEGO building. While it has 3599 pieces (and comparing it to the other sets in the lists, this looks like a piece of cake), the Bugatti Chiron can be a pain in the neck, literally and figuratively. Collectors have found that this set has tested their patience more often than not, but we can guarantee that the outcome is as beautiful as the real thing itself.

UCS Imperial Star Destroyer (75252)

What’s a LEGO list without a few Star Wars sets, right? The Imperial Star Destroyer sits at #7 on the list holding more than 4780 pieces. The arrowhead-like design is a feast for the eyes, whether you’re a Star Wars fan or not. Keep in mind that building this set is tedious and if you have plans of keeping it on display make sure that it’s far away from anything that can knock it down.

Ghostbusters Firehouse Headquarters (75827)

If there’s something strange in your neighbourhood, who do you call? Ghostbusters!

Ghostbusters is a pop culture mainstay, thanks to a string of successful films in the 80s. A group of 5 men try to combat beings of otherworldly existence in New York City and their iconic firehouse headquarters has now turned into a LEGO set!

What’s amazing about this set is its playability – each room has been carefully and meticulously thought through to give the collector a memorable playing experience.

Harry Potter Hogwarts Castle (71043)

Harry Potter continues to mesmerize the world and the beloved school where The Boy Who Lived and his friends has now come to life thanks to LEGO!

Just like all the other sets in this list, building the Hogwarts Castle from scratch can be tiring. There are small details too like stickers that make the whole set more believable. Binge watch the entire Harry Potter series whilst you put in some elbow grease into this set and you’ll be done in no time!

Volkswagen T2 Camper Van (10279)

Don’t be fooled by the numbers – the Volkswagen Camper Van is one of the hardest sets to build. Because of the details and smaller LEGO pieces, this set is marked as “expert” levels on the box and for good reason too. Just like the Bugatti, if you are a car enthusiast with a penchant for building LEGO sets, grab a box of Volkswagen T2 Camper Van today!
