A structure block is used to generate structures manually. They can also be used to save and load structures, alongside structure void blocks.

Structure blocks are available using the /setblock, /fill, or /give commands, or the Creative inventory in Java Edition through the "Operator Utilities" tab. When placed, structure blocks are unbreakable in Survival and have the same blast resistance as bedrock. In Bedrock Edition, only save-mode structure blocks are obtainable through commands in the inventory.

When placed, use the structure block to open its GUI. The GUI opens only if the player is in Creative mode, and has permission level 2 or higher.

Once a structure is named, its name appears above the structure block when highlighted, preceded by the block mode (e.g. "Save:minecraft:example").‌^{[Java Edition only]}

Switching between modes preserves the settings of the structure block wherever possible.

In item form, the structure block uses a "blank" texture, a texture that is not used when on a placed block.

Structure blocks can't be moved by pistons, and can't be destroyed by the ender dragon.

Save mode allows the player to highlight a structure in the world and save it to memory, level file, or a separate file.‌^{[Bedrock Edition only]}

Structure Name

A text box for entering the resource location of the structure to be saved. Only some characters are allowed. In Bedrock Edition, it has a "mystructure:" prefix by default.

Relative Position / Offset

The X, Y, and Z offsets of the structure, relative to the bottom north-west corner of the structure block. Sets the origin of the structure outline.

In Java Edition, the origin must be at most 48 blocks away in all directions. In Bedrock Edition, the origin must be at most 64 blocks away horizontally, and 384 blocks vertically.

Show invisible blocks‌^{[JE only]}

Displays invisible blocks as small colored cubes. Off by default.

Structure Size / Size

X, Y, and Z offset from the Relative Position coordinates. This sets the opposite corner of the structure, and defines the structure's size.

The maximum structure size is 48×48×48 in Java Edition and 64×384×64 in Bedrock Edition.

When successful, generates an outline surrounding the structure that's mostly white except for the red, green and blue lines that represent the X, Y and Z axis. In Bedrock Edition, the structure also gets previewed with a rotatable 3D model inside of the structure block's GUI.

Detect structure size and position / Detect

Automatically calculates the size and position of the structure using a corner block placed on the opposite corner of the structure.

The name of the structure in the save block must match the name within the corner block, or the size calculation fails.

Two corner blocks can also be used. It uses the second corner block instead of the structure block.

Include entities

When saving the structure, if this option is on, saves any entities within the structure as well.

Remove blocks‌^{[BE only]}

When saving the structure, if enabled, no blocks are included in the structure.

Redstone Save Mode‌^{[BE only]}

Sets the save location for the structure file when the structure block gets activated by redstone. Save In Memory stores the structure in the game's loading memory, which will be lost after leaving the world, while Save To Disk stores the structure permanently in the level files.

Show Bounding Box‌^{[BE only]}

Toggles the outline of the structure, both in the preview and in the world.

Save

When all coordinates and a structure name have been entered, press this button to save the structure.

In Java Edition, this saves the structure to a file. The name of the structure is the name of the file.

Structures can be saved to a file only by manually pressing this button. If a structure block in Save mode is instead powered by redstone, the structure is only saved in memory. This is the case even if a file for that structure already exists on disk. Reloading the world clears any structures stored in memory. This is for unspecified security reasons.^[2]

If no namespace is specified, a default value of minecraft is used. This can be changed by prefixing the structure name with <namespace>: in the structure block.

Structures are saved in .minecraft/saves/(WorldName)/generated/(namespace)/structures.^{[note 1]}

In Bedrock Edition, this saves the structure into the level database file rather than a standalone file.

Export‌^{[BE only]}

Used to export a structure into a .mcstructure file, which can be used to load from the structures folder of a behavior pack or import in a Load structure block. If the structure contains a custom block from a behavior pack, then the block is also saved on the structure block. This option is only available on Windows devices by default and Android with resource packs however, starting with version 1.21.130, the button becomes completely useless on Android, as exporting to unsupported platforms has been removed.

👁 BlockSprite structure-block-load.png: Sprite image for structure-block-load in Minecraft
Load mode allows the player to load and rotate saved structures.

Structure Name

The name of the structure to load.

In Java Edition, structures are searched in the following order:

• from memory
• from a file (.minecraft/saves/<World Name>/generated/<namespace>/structures/)
• from data packs
• built-in structures from minecraft.jar

In Bedrock Edition, structures are searched for in the following order:

• from memory
• from disk (level database)
• from behavior packs

In Bedrock Edition, vanilla NBT structure files cannot be loaded with structure block.

Relative Position / Offset

The X, Y, and Z offsets of the structure, relative to the bottom north-west corner of the structure block. Coordinates may be specified as numbers between -48 and 48 in Java Edition, or between -64 and 64 horizontally, and -384 and 384 vertically in Bedrock Edition.

Show bounding box

Highlights the outline of the structure. On by default.

Structure Integrity and Seed

Removes random blocks that compose the structure based on a user-defined seed.

Lower integrity values result in more blocks being removed. The integrity value must be between 0.0 and 1.0‌^{[JE only]} or 100.00.‌^{[BE only]}

Strict Placement‌^{[JE only]}

When on, the blocks of the structure do not emit block updates or run their post-placement code when the structure gets loaded.

Include entities

Include any entities saved in the structure file when loading the structure. Off by default. In Java Edition, due to MC-103452, passenger entities aren't saved.

Waterlog Blocks‌^{[BE only]}

When loading the structure blocks that replace water become waterlogged instead of replacing blocks with air, creating air pockets.

Remove Blocks‌^{[BE only]}

When loading the structure, don't include any blocks from the saved structure.

Rotation (0, 90, 180, 270)

Sets the rotation of the structure to 0° (no rotation), 90° clockwise, 180° clockwise, and 270° clockwise (or 90° counter-clockwise).

Mirror (¦, <>, ^v)

Sets the mirroring of the structure to none (¦), left to right (< >), or front to back (^ v). At 0° rotation < > mirrors across the X-axis and ^ v mirrors across the Z-axis.​^{[more information needed]}

In Bedrock Edition, the options are x and z, which can be toggled to set mirroring.

Animation Mode‌^{[BE only]}

Select the animation to show how structure is loaded. Place by Layer makes structure loaded layer by layer, Place by Block makes structure loaded one block by block. Default to none.

Once the loading has started, breaking the structure block can not stop the loading process.

Loading with animation may break blocks in structures that contain multiple parts (such as beds, doors, or tall grass), or need to be attached to other blocks (such as torches), and may cause water, lava, and fire to spread out.

Animation Time‌^{[BE only]}

Adjust the animation time in seconds for loading the structure.

Load

Press to load the structure.

In Java Edition, press this button once to prepare the outline preview of the structure. When satisfied with the position, press again to generate the structure.

A redstone signal will also activate the structure block and load the structure.

Import‌^{[BE only]}

Only available on Windows. Opens the file explorer and allows to select a .mcstructure file exported from a Save structure block. This imports the structure into the memory, allowing to use its save name to load (entered by default).

👁 BlockSprite structure-block-corner.png: Sprite image for structure-block-corner in Minecraft
Corner mode allows for an easier and automatic size calculation while saving or loading structures.

To use, place on the opposite corner of a save structure block or a second corner structure block. Then, using a save block, press "DETECT".

When successful, a bounding outline appears.

Structure Name

The name of the structure on which to calculate the size and position.

Name is case sensitive,‌^{[BE only]} it must match exactly with the name provided by the complementary save or corner structure block.

👁 BlockSprite structure-block-export.png: Sprite image for structure-block-export in Minecraft
3D Export mode,^{[note 2]} is similar to Save mode, but the structure is saved as a 3D render in the format of .glb rather than as an actual structure.^[3] Therefore, structures saved this way can be viewed with 3D Viewer^[4] or Paint 3D^[5], but cannot be generated via load mode.

The 3D file exported is basically the same as the real-time rendering in the preview. Animated textures such as Nether portal blocks, liquids, magma, etc. only have a static texture. Some blocks cannot be displayed properly, such as piston arms, chests, beds, etc. including entities is not supported in this mode.

Structure blocks in 3D export mode cannot be activated by redstone.

3D export can't be used in Marketplace world templates.

Structure Name

Enter the name of the structure. Case sensitive. The player must enter a file name in order to export.

Size

Enter the X, Y, and Z values to set the distance from the Relative Position coordinates. This sets the opposite corner of the structure, and defines its size.

Maximum structure size is 64×384×64.

Offset

Enter the X, Y, and Z values for the structure here, based on the position of the structure block. Sets the origin of the structure outline.

Maximum allowed distance from the structure block is 64 blocks in any direction.

Remove Blocks

While exporting the structure, doesn't include any blocks within saved structure.

Show Bounding Box

Toggles the outline of the structure, both in the preview and in the world.

👁 BlockSprite structure-block-data.png: Sprite image for structure-block-data in Minecraft
Data is a deprecated mode, which is superseded by the jigsaw block, but still used in some certain vanilla structures (igloo, end city, woodland mansion, ocean ruin, shipwreck). Structure blocks in data mode can be used only during natural generation. They mark the location to run a specified hardcoded function, which can be used only for relevant structures. In Java Edition, this mode is hidden unless the key is held while switching from Corner mode. In Bedrock Edition, data mode structure block cannot be obtained with commands.
