Gone are the days kids got to have all the fun; the best Lego sets for adults bring all of the joy of building a new set, but are more complex with a more refined finish.
In recent years, Lego has begun producing a wide range of adult-friendly sets (which are also suitable for older children and teenagers), meaning we had plenty to choose from when compiling our favourites. To whittle it down, we looked at everything from the brick count to the relevancy of the intellectual property, the complexity of the build, and lastly, the look and feel of the finished results.
Naturally, we couldn't include every set we love in here, so make sure to check out our pick of the best Lego City sets, best Lego architecture sets, best Harry Potter Lego sets, or our best Lego space sets.
