Designing your own LEGO® creations sounds like an amazing idea, and with LEGO® Alternate builds you can do that.

These alternative builds are designs that people created using bricks from official LEGO® sets. However, these are using the same LEGO® pieces in an entirely new way. That means you don’t have to buy a new LEGO® set, you can just use what’s already there to create something entirely different!

What Are LEGO® Alternate Builds?

The official LEGO® sets are restrictive since they have a limited amount of pieces and you don’t have to build in a certain way. That makes the LEGO® Alternate builds a lot of fun since you can even use variations if you want.

Normal LEGO® sets will usually have a single item you can create, maybe up to 3 if it’s a 3-in-1 set. But with the LEGO® alternative builds you can get beyond that. You can finally use the same LEGOs to create new things. 

All you need is to follow our designs listed below, and you can breathe new life into your current LEGO® sets.

Types of LEGO® Alternate Builds

1. LEGO® Alternate Build

This type of LEGO® Alternate Build is when you take an official LEGO® set and make something else from the bricks within the set.

The biggest rule with this type of design is that you do not use any other bricks other than what is included within the set.

Examples of a LEGO® Alternate Build are:

LEGO Alternate Build 31129
alternate build 10211
T-Rex Dinosaur alternate build 31088 + 31058

2. LEGO® Modification Build

A Modification Build is similar to an Alternate Build whereas you use an official LEGO® set to make your design but there is one big difference.

You can use additional bricks outside of what is included in your set!

This makes the modification build designs incredibly interesting because when it’s done with an already well-designed LEGO® set adding more similar types of bricks to expand it can result in some unbelievable designs.

Some examples of Modification Builds are below.

Hey, I am Matthew Mitchell and I am an AFOL from the UK. I have been fascinated by LEGO® since I was a child. My two children are in love with LEGO® and it's because of them that my interest continued to grow, this is how I fell in to the rabbit hole of MOCs (my own creation). 

With every new MOC I saw I became just a bit more addicted to the endless possibilities that LEGO® offers. This led me to creating Belle-Ve Bricks, a platform where talented designers can share their work with the world.

And where we can create together with you, custom models.
