Structure Builder is a Bedrock addon from Sr_Dicov that imports .mcstructure files and places them in a survival world through a menu, with no commands. It is a structure builder addon for players who want to drop in their own designs without switching to Creative mode. The hybrid design is meant to limit interference with the base game, so achievements stay available.
Supported versions
- Minecraft 1.21.130.
What it adds
The addon adds no new items. It turns an ordinary stick into the control tool, and everything else runs through menus.
- Support for up to 1000 structures, each picked from a catalog by number, with an optional custom name such as Watchtower.
- Placement on the block you strike, with a confirmation menu that shows the coordinates. The structure rotates to face you.
- A demolition tool that clears an area after you strike three points: two opposite base corners, then any block at roof height.
Setting it up
The addon reads structures by number, so your files need prepping before use. Follow the general steps in how to install add-ons on Bedrock for importing the .mcaddon file.
- 1.Rename each .mcstructure file to a sequential number, such as 1.mcstructure, 2.mcstructure and 3.mcstructure.
- 2.Place the numbered files in the Structure Builder BP pack, inside its structures folder. Do this before installing or while editing the .mcaddon file.
- 3.In game, rename a stick on an anvil to "build", all lowercase.
- 4.Hold the stick and right-click (or long press) to open the catalog, choose a structure and press Select Structure.
- 5.Strike the block that will be the centre of the base, check the coordinates and confirm.
Limits to know
The trade-off is manual setup. You supply and number every structure yourself, and the menu labels them Structure 1, Structure 2 and so on until you rename them.
Questions about Structure Builder.
4 questions
Does Structure Builder disable achievements?
No. The addon uses a hybrid design meant to minimize interference with the base game, so achievement progression keeps working. It also runs entirely in survival, so you never need to switch to Creative mode to place or clear structures.
Why do I get a "Could not load" error in Structure Builder?
The error appears when you try to place a slot that has no matching file. If you pick Slot 50, a file named 50.mcstructure must sit in the structures folder of the Structure Builder BP pack. Check the numbering and the location.
How do I open the Structure Builder menu?
Rename a stick to "build" in lowercase on an anvil, then hold it. Right-click or long press to open the structure catalog. Striking a normal block with the stick places the selected structure at that spot.
Is there a size limit for clearing areas with Structure Builder?
No strict limit exists in the code. Clearing areas above 32x32x32 blocks may end up incomplete if the game cannot load every chunk at once, so the creator advises demolishing very large structures in sections.
