Blueprints

Blueprints are structures that can be generated once you have obtained them (usually by finding them in treasure chest or by completing random NPC Quests). They are automatically added to your library once you have found them and may need additional purchase before you are able to use them.

To spawn the blueprint, go to your Brick Builds menu as seen on the image below. You may have to purchase blueprints before you get to spawn them. Upon purchase, simply pick the structure and spawn it in the world similar to how you spawn your copied structures (brick builds).

You may have to purchase blueprints prior to spawning them

The Pirate Clock Tower on the first world (Pirate Playground) is an example of a blueprint
