The Big Experiment: AI-Assisted LEGO-Compatible Build Planning
Use our generators to produce structured plan packs you can validate in BrickLink Studio or real bricks — with parts lists, step-by-step guidance, and practical QA checklists.
Explore featured vehicles, generate structured build plans,
and grab copy-ready tools for everyday life—fast, clear, and focused on real-world building.
Lego Fan Plans are legit, high-quality building instructions made for real builders—at the kitchen table, in the classroom, or in any maker space. Over the past decade, our team has created hundreds of step-by-step projects designed to spark curiosity, strengthen spatial thinking, and bring families together.
For an extra dose of reality, you can load each build package into BrickLink Studio to review the model, parts, and steps before you start. We believe play should be inclusive, fun, and educational—so we create clear, colorful guides anyone can follow anytime, anywhere.
Our library spans many themes—from cityscapes to space and beyond—providing easy-to-follow guides for sets of all sizes. Builders can reuse techniques across projects, discover new ideas, and extend play beyond the box. Each guide includes clear steps, parts lists, and optional customization tips.
What “Buildable” Means Here
- Locked BrickLink Studio (.io) for the exact build
- Matching Wanted List XML / parts list exported from that file
- Instructions aligned to that locked BOM (step-by-step or module steps)
Research note
Some current research (often described as
BrickGPT/LegoGPT
explores generating brick builds brick-by-brick from text prompts, then pruning unstable or invalid
placements using assembly and physics-aware checks during generation.
Our approach is practical and
creator-friendly: we generate an end-to-end build spec with a BOM strategy and executable step breakdown,
then mark a build VERIFIED only when the locked Studio model + matching exports are included;
otherwise it stays DRAFT until Studio validation is complete.
