About BuildaMOC
We turn models into custom brick kits.
We license models from independent designers, source the parts and pack each model as a complete kit of original LEGO® elements. We also design kits for companies, based on their own products.
- Original LEGO® bricks
- MOCs licensed from designers
- In-house sourcing and packing
- Worldwide shipping
The model is the fun part. Finding every brick is not.
Building somebody else's MOC usually starts with a part list and a lot of admin: checking availability across sellers, placing several orders, waiting, sorting what arrives, and finding out somewhere around step 40 that a handful of pieces never came.
That is the part we took on. You get one box with the parts, the instructions from the designer, and a person to write to when something is wrong.
What we hold to
Original bricks
We use original LEGO® elements only. No clone parts, whatever the margin would be.
Designers stay part of it
Every design is licensed and credited, and at least 10% of each kit sale goes to the designer.
Kits prepared by our team
Someone counts the parts and checks the list again before it ships.
A person writes back
When you write to us, a person reads it and replies.
How we got here
It started because buying the parts was the worst part.
Independent designers were publishing models that very few people could build, because sourcing several hundred specific elements is a project in itself. Some of those designs were also being copied by clone brands.
So we started making complete kits ourselves. We licensed each design from its creator, bought the elements and bagged them by step. As the catalog grew, we built up our stock and set up our own printing.
Then companies started asking whether we could do the same thing with their product, their building or their logo. That work is now the larger half of what leaves the workshop, and it runs on exactly the same operation.
-
One kit at a time
We sourced the parts for other people's designs by hand, from whichever sellers had them.
-
Designers on board
Licensing agreements with independent creators, and a share of every kit sold.
-
Our own stock
Buying deep rather than per order, so kits stopped depending on one seller.
-
Printing and packaging in-house
We print booklets, sleeves and inserts in-house instead of buying them in.
-
Production for companies
Custom models, branded packaging and runs delivered to offices and events.
The people who pick your parts
Our own team prepares and checks every kit before it ships. We also do design, sourcing and support in-house.
A company order and a single kit from the catalog go through the same picking tables.
A lot happens before the box leaves us.
Stock walls, sorted elements, picking tables, printing, boxes and the finished builds.
Custom models by independent designers
Most of what we sell was designed by somebody in the community: JK Brickworks, Akiyuki, TonyFlow76, Planet GBC, Klosspalatset, Nico71 and dozens more. They keep the credit and they get paid on every kit.
If you have designed something you think should be a kit, we would like to see it.
How it works for designers
- You send the model and the part list.
- We check sourcing and agree on terms.
- We list it, prepare the kits and handle support.
- You receive at least 10% of every sale.
Brick kits also work well away from the hobby shelf.
Most of what we make now is for companies. They order kits as gifts for clients and employees, for events, product launches and offices, and sometimes one large display model. For those projects we also design the model and the branded packaging.
BuildaMOC operates internationally and also maintains BuildaMOC, Inc., a U.S. corporation incorporated in Delaware. If you're buying from the United States, see how we work with U.S. companies.
Questions people ask us
What is a MOC?
"My Own Creation", a custom model designed by a builder rather than released as an official set. More on that here.
What comes in a kit?
Every part needed for the build, bagged, plus the designer's digital instructions, which we email to you when your order ships.
Do you really only use original parts?
Yes. Every kit we ship uses 100% original LEGO® elements.
Where are you based?
We're a registered company in Seville, in the south of Spain. We prepare every kit there and ship worldwide.
Is this an official LEGO® product?
No. We work with original LEGO® elements that are repackaged or altered from their original form. The LEGO Group does not sponsor, authorize or endorse what we do.
