Some of the largest LEGO sets can take hours to complete

There are some seriously huge LEGO sets on the market these days! From replicas of iconic buildings to movie-themed playsets, there's something for everyone. Just be warned - some of these sets can take days or even weeks to complete! Keep reading to see a list of some of the biggest and baddest LEGO sets you can get your hands on.

 LEGO Diagon Alley: 5,544 pieces

When people say toys can help you escape to ‘your own little world’ they were probably thinking of something smaller than the Diagon Alley LEGO set. This set is the closest we muggles are likely to ever get to being able to see the cobblestoned wizarding alley from Harry Potter.

In it is a mixture of magical restaurants and shops from which you can buy everything from the Hogwarts supply list including a magical wand from Ollivanders Wand Shop. Unfortunately, Rubeus Hagrid may not be coming to knock on our doors any day soon to take us for a shopping spree but it’s possible to get a pretty similar experience with this LEGO 75978 set.

This epic model is over a metre wide and filled with details from the films as well as 14 LEGO minifigures including Draco, Hermione, Ron and, of course, Harry Potter himself.

LEGO Titanic: 9,090 pieces

If someone were to say “structurally sound things” in a word association game, then the Titanic may not be the first thing to come to most people’s minds. However, the LEGO version comes apart in all the right ways.

It is not just the exterior of the boat that you build, but the internal makeup of the famous vessel is also intricately designed and a crucial part of the building experience. It has a remarkable cross-section that shows off parts of the boat such as the smoking lounge, boiler room, grand staircase and more. The fact that it’s designed so you can divide it into three sections to explore the fascinating interior means you’ll have just as much fun showing off the inside as the outside.

Tons of great features from the castle are packed in here. You have the Whomping Willow and the blue Flying Ford Anglia car which it has given a famous beating to. The Great Hall with the famous stained-glass windows and moving staircases and if you’re brave enough, the Chamber of Secrets is here to be put together (if you can face the terror of the Basilisk). If you want somewhere that feels a bit safer, then get to work on Hagrid’s Hut, although Aragog the spider will need to be placated too!
