Lego enthusiasts can amass collections worth thousands of pounds, so it's worth checking your bricks are protected in case of loss or damage.
With Lego-themed amusement parks located throughout the world, those little bricks are big business.
However, it is still the humble home Lego enthusiast that is at the heart of this multi-national company.
A small set of Lego can quickly grow in to a more extravagant collection as we found out when we discovered a number of enthusiasts here at Confused.com.
Jamie Gibbs, 27, a digital marketing executive at Confused.com, has an impressive Lego collection of 5,000 bricks worth around £700.
'I never grew out of Lego'
He says: "Like most people I got Lego sets when I was a kid, and it was something that I just didn't grow out of.
"There are a lot of sets that are tailored more towards the adult population and they can actually help you learn about architecture.
"Some people keep their Lego stored up in boxes to gain value but that isn't really the point of it if you ask me - Lego is there to be enjoyed.
"I suppose there is a little bit of a stigma attached to adults buying toys, but I think more and more people realise they are a great way to use your imagination.
"I think its popularity will continue to rise."
'I spent £2,000 on my Lego collection'
Analyst Chris Williams, 29, started collecting Lego two years ago after receiving a set as a present.
Since then he has spent around £2,000 on approximately 8,000 pieces of Lego.
This includes a customised model of our very own BRIAN the Robot, which took Chris 18 hours to build.
Williams says: "I really enjoyed making BRIAN.
"It did take a long time to build though, as I had to take pieces from a different collection and use my imagination to put it together correctly.
Lego R2-D2 & BRIAN the Robot
"For me Lego is a hobby and I find it very relaxing working out how to put together the different sets.
Williams stores all his Lego pieces in a games room where one of his most prized possessions is a model of Star Wars' R2-D2 worth £150, as well as his BRIAN the Robot model.
He adds: "As my collection has grown in value I have started thinking about protecting it by adding it to my home insurance.
Gareth Lane, head of home insurance at Confused.com, says serious Lego collectors should ensure their valuable sets are covered.
Insuring your Lego collection
He says: "Like all collections of works of art and curios - rare, unusual or intriguing objects - it's important to make sure these items are insured.
"In most cases your home insurance policy will cover your Lego collection.
"However, high-value collections worth more than £1,000 may have to be listed separately on your home insurance policy.
"This is likely to incur an extra cost, but it should guard you against a greater financial loss should anything untoward happen to your precious collection.
"It may also be required for the items to be independently valued or that you have proof of possession and condition of the items."
