Behind the Bricks: What It Really Takes to Turn a Fan Build Into a LEGO Set
One of our favorite parts of Brick Blast is seeing incredible fan creations up close. Every builder has a different approach, and sometimes a simple idea turns into something that makes everyone stop and stare.
We recently sat down with Alex Castellic, director of the BrickLink Designer Program, to learn what actually happens behind the scenes when a fan-designed model becomes a real LEGO set. Here are the biggest takeaways every builder should know.
Bigger isn't always better
One of the biggest surprises? More pieces don't automatically make a stronger design.
Alex explained that many fan creations can become more competitive by simplifying unnecessary details without losing what makes them special. A cleaner, more efficient build often stands out just as much as a massive one.
Builder tip: Before calling a MOC finished, ask yourself: does every piece earn its place?
Start with what you love
If you're thinking about submitting a design someday, don't chase whatever theme seems most popular.
Instead, build something you're genuinely excited about. Whether it's trains, castles, sci-fi, or city buildings, passion usually leads to better designs—and you'll enjoy the process a lot more.
Small builds deserve more love
One of the most interesting insights was that smaller models are often underrepresented.
While giant castles grab attention, there's plenty of room for clever builds with fewer pieces. A great idea at a smaller scale can be just as memorable—and sometimes fits the program's lineup more naturally.
It's a good reminder that creativity isn't measured in part count.
Community voting is only part of the story
The BrickLink Designer Program is driven by community voting, but the final lineup also has to balance themes and model sizes.
That means a highly voted castle, for example, might lose out if another castle has already been selected and a different-sized model helps create a more balanced wave.
It's less about replacing the vote and more about building a lineup that works together.
AI has a limit
Alex drew a clear line when it comes to AI.
Using AI to help create temporary sticker artwork is acceptable because LEGO's graphic designers recreate that artwork before production. But using AI to generate the LEGO model itself goes against the purpose of the program.
The creativity behind the build still needs to come from the builder.
Why this matters at Brick Blast
One thing stood out throughout the conversation: the best builders never stop learning.
They study techniques, experiment with new ideas, simplify when needed, and keep improving with every build.
That's exactly what makes Brick Blast special.
Whether you're displaying your first MOC or your hundredth, every creation has the chance to inspire someone else's next idea. You never know which clever technique, hidden play feature, or unique design will become the thing everyone remembers.
And that's what this community is all about: building, sharing, and inspiring the next great creation
