The Top 10 LEGO Sets With Unique Pieces

Which set has the most unique parts?


At 11,695 pieces, the LEGO Art World Map is the biggest LEGO set ever sold. But did you know it only has 32 unique piece types? As LEGO builds go, that's not a lot of variation. In fact, it's one of the least varied sets available.

Whilst this lack of variation is common in the LEGO Art theme, other large LEGO sets have also been guilty of repetition and monotony in the past. Both the LEGO Tower Bridge and the Taj Mahal have caused LEGO builders pain due to the low part variation resulting in a repetitive build. Tower Bridge has 4,287 pieces but just 192 unique piece types. Meanwhile the Taj Mahal has 5,923 bricks but even fewer unique brick types with 165.

Taking the assumption that the more unique LEGO pieces used to build a set would make for a more interesting build, we set about investigating which of our top 30 biggest LEGO sets had the most unique parts using the inventory counts at Rebrickable. The results may surprise you...

7. LEGO Star Wars UCS AT-AT Walker

  • set: 75313
  • pieces: 6,785
  • minifigures: 9
  • Availability: Out now

The latest LEGO Star Wars UCS set has 657 unique parts.

The giant walker requires around 800 Technic connectors to hold it together!

But there's still lots of unique parts in here, including a single pink brick that LEGO designers try to hide in many of the Star Wars sets in return for cake.

6. LEGO Star Wars UCS Millennium Falcon

  • set: 75192
  • pieces: 7,541
  • minifigures: 10
  • Availability: Out now

Despite being the largest LEGO Star Wars set, the Millennium Falcon has 676 unique pieces. This is in part thanks to the sheer number of Technic connectors that are used to keep the giant spaceship together, and partly due to the amount of grey.

Still, the grey is broken up with maroon and tan pieces, and the build never feels monotonous.

5. LEGO Titanic

  • set: 10294
  • pieces: 9,090
  • minifigures: 0
  • Availability: Out now

If you speak to anyone about their experience of building the Titanic, they will probably mention the portholes. Let's just say there's a lot of them.

But with 9,090 pieces, there's also a far amount of variation. The LEGO Titanic includes 692 unique parts.

4. LEGO Home Alone

  • set: 21330
  • pieces: 3,955
  • minifigures: 5
  • Availability: Out now

With 3,955 pieces, Home Alone sits fairly low on our top 30 biggest LEGO sets list - but it sits high up on this list with 739 unique pieces.

To look at the Home Alone house, you may be wondering how this is possible - the brown exterior walls do make up a lot of the larger brick quantities in the set (143 brown 2x1 brick pieces anyone?). But there are a ton of single quantity unique bricks that make up the interior of this build.

  • set: 70620
  • pieces: 4,867
  • minifigures: 16
  • Availability: Retired

There are 920 unique brick types in the 4,873 brick NINJAGO City set.

The unique look and feel of the city with each floor representing a different age and time helps ensure there is lots of variation in brick and a ton of variation during the build. Even if you're not a fan of NINJAGO, there is a lot to enjoy here!

2. LEGO Harry Potter Diagon Alley

  • set: 10217
  • pieces: 2,025
  • minifigures: 12
  • Availability: Retired

Diagon Alley is our first LEGO set to hit the 1k mark in terms of unique parts - with 1,013 unique pieces.

That must be in part thanks to the modular structure of Diagon Alley's four buildings which can be treated as four completely separate LEGO sets.

1. LEGO NINJAGO City Gardens

  • set: 71741
  • pieces: 5,685

LEGO Fans often say NINJAGO Gardens is one of the best LEGO sets to build, and it's not hard to see why when you count its unique parts list. There are a whopping 1,125 unique pieces in this set.

That's not to say there isn't any repetition. As with the other NINJAGO City Modular sets, this set also sits on a base of water which consists of 328 translucent blue tiles. But after these first steps, you'll soon be building a unique and colourful structure!
