Understanding How Custom LEGO Builds Work

If you’re a fan of LEGO and want to go beyond official sets, you might be wondering: How do custom LEGO builds work? Let’s break it down. Custom LEGO builds—often called “MOCs” (My Own Creations)—let builders around the world design, create, and sometimes sell or share entirely new models using standard LEGO bricks. These builds open a universe of endless creativity and allow you to experience LEGO in a fresh, personal way.

Below, we’ll cover what custom LEGO builds are, how you can make (or buy) your own, the benefits and challenges involved, practical tips, and answers to frequently asked questions.


What Are Custom LEGO Builds?

Custom LEGO builds (MOCs) are unique models designed by LEGO enthusiasts. Unlike official LEGO sets, these models are crafted by fans using their imagination, software tools, or even by modifying existing sets. Here’s what makes a build “custom”:

  • Designed from scratch or heavily modified from existing models.
  • Frequently accompanied by step-by-step instructions or digital files.
  • Built using real LEGO bricks, sometimes mixed with 3rd-party accessories or printed elements.

Custom builds can range from small figures to massive display sets—think of anything from animals and vehicles to famous landmarks or fictional scenes.


Main Steps to Create or Acquire Custom LEGO Builds

You can approach custom LEGO builds in two main ways: designing your own, or building from someone else’s instructions.

1. Building from Existing Instructions

Many talented builders share or sell instructions for their MOCs online. To build one of these models, you usually follow these main steps:

  1. Find a Model
  2. Visit marketplaces or communities where builders post MOCs.
  3. Browse by theme, difficulty, piece count, or designer.

  4. Get Instructions

  5. Purchase, download, or access the build instructions (these might be PDFs or digital files).
  6. Some platforms offer free instructions, while others charge a fee.

  7. Gather Pieces

  8. Check the parts list provided with the instructions.
  9. Use your own LEGO collection or buy parts individually.
  10. Some sites offer complete kits, including all the required bricks and instructions.

  11. Build the Model

  12. Follow the step-by-step instructions, just like an official LEGO set.

2. Designing Your Own Custom LEGO Build

For creative minds, designing your own model is half the fun. Here’s how many custom builders do it:

  1. Get Inspired
  2. Choose a theme, object, or idea that excites you.

  3. Plan Your Build

Where to Find Custom LEGO Instructions and Kits

Many online platforms are dedicated to the custom LEGO community. While each varies in its offerings, you can typically expect to find:

  • A vast library of unique models (“MOCs”) with instructions.
  • The ability to buy digital instructions or complete kits.
  • Custom minifigures and specialty printed parts.
  • Community reviews and ratings.
  • Support for part sourcing or even one-click ordering of required bricks.

Look for platforms that align with your interests and budget. Some specialize in high-end display models while others offer builds ideal for play.


Benefits of Building Custom LEGO Models

Custom LEGO builds offer many advantages, making them a favorite among hobbyists:

  • Unlimited Creativity: Build anything you can imagine, not just what’s available in stores.
  • Skill Development: Improve your engineering, design, and problem-solving abilities.
  • Unique Displays: Decorate with models you won’t find on store shelves.
  • Community Connection: Join a passionate group of builders; share ideas, feedback, and creations.
  • Flexible to All Ages: Find builds that suit young kids, adults, or advanced builders.

Challenges and Considerations

While custom LEGO builds are rewarding, they come with their own set of challenges:

  • Part Availability: Not all bricks are easy to find, especially in certain colors or rare elements.
  • Cost: Buying individual parts (or kits) can be pricier than traditional sets.
  • Complexity: Some instructions assume advanced building skills and may not be ideal for beginners.
  • Time: Designing or sourcing custom models may take longer before you can start building.
  • Shipping & Import Fees: Acquiring rare bricks or full kits from international sellers may increase costs due to shipping and customs.

Practical Tips and Best Practices

Ready to dive into custom LEGO building? Keep these practical pointers in mind:

Tips for Building from Instructions

  • Sort Your Parts: Before starting, organize bricks by color and shape—it saves lots of time.
  • Check Inventory Carefully: Double-check that you have all necessary parts before starting.
  • Take Your Time: Some steps in custom instructions can be tricky—build at your own pace.
  • Join Online Communities: If you get stuck, many fan forums can provide help or clarification.

Tips for Designing Your Own Builds

  • Start Small: Tackle simple models before working up to complex ones.
  • Use Digital Tools: They make planning and error-checking much easier.
  • Think About Structure: Focus on both appearance and stability. A model that looks great but falls apart easily isn’t much fun.
  • Document as You Go: Take notes or photos of progress; it’ll help if you need to rebuild or want to share instructions.

Sourcing and Cost Tips

  • Buy in Bulk: Platforms that sell custom kits may offer savings when buying multiple models or pieces.
  • Watch for Shipping Costs: International shipping and customs fees can add up quickly—combine orders when possible.
  • Use Reputable Sellers: Find platforms with strong reviews and clear return policies.
  • Leverage Local Communities: Brick swap meets and local LEGO clubs are great for finding parts inexpensively.

Cost Considerations

Building from Your Own Collection

  • Low Cost: If you already own many bricks, you might only need a few extras.

Buying Individual Pieces

  • Moderate to High Cost: Rare bricks or large quantities can add up, especially if orders are split across different merchants.

Purchasing Complete Custom Kits

  • Higher Cost: Full kits (with instructions and all necessary bricks in new condition) are usually more expensive than official sets of similar size, due to sorting, packaging, and labor involved.
  • Shipping: Kits shipped internationally may price in taxes, customs, and higher postage—double-check before completing your purchase.
