Public Build Projects Overview
Public Build Projects help you plan, build, and share a LEGO project on BrickZap.
A project can track the parts your build needs, show what you already have, highlight what is missing, and give others a place to follow your progress.
What a build project is
A build project is a workspace for one build.
You can use it for a set you are completing, a MOC you are sourcing, or a custom creation you are designing from scratch.
Supported project types
Official LEGO SetUse this when your build is based on a catalog-backed LEGO set.
Rebrickable MOCUse this when your build is based on a Rebrickable MOC. In the first version, MOC details are saved as project metadata.
Custom ProjectUse this for your own creation, restoration, display build, alternate build, or parts experiment.
Visibility options
Private projects are only for you. Unlisted projects can be shared by link, but are not meant for public discovery. Public projects can be viewed by visitors and followers.What followers can see
Followers can see the public project page, published progress, public or project-visible updates, summary counts, and public instruction downloads.
Followers do not see private owner inventory details.
How progress is calculated
Progress is based on required parts compared with owned parts.
If a project needs 100 parts and 70 are covered, the project is about 70% complete.
Required, owned, and missing
Required means the quantity the build needs. Owned means the quantity BrickZap counts as already covered for the project. Missing means the quantity still needed to complete the build.Why projects help with sourcing
Projects make missing parts easier to act on.
Instead of searching one part at a time, you can see the build as a whole, focus on what is missing, and use BrickZap marketplace tools to find sellers.
