Use Command Block to Build a Castle with One Command

This Minecraft tutorial explains how to program a command block to build a castle from only one command in Minecraft with screenshots and step-by-step instructions.

console command

Let's explore how to do this.

Supported Platforms

This command block program is available in the following versions of Minecraft:

Platform	Supported (Version*)
Java Edition (PC/Mac)	Yes (1.8)
Pocket Edition (PE)	No
Xbox 360	No
Xbox One	No
PS3	No
PS4	No
Wii U	No
Nintendo Switch	No
Windows 10 Edition	No
Education Edition	No

* The version that it was added or removed, if applicable.
NOTE: Pocket Edition (PE), Xbox One, PS4, Nintendo Switch, and Windows 10 Edition are now called Bedrock Edition. We will continue to show them individually for version history.

Required Materials

In Minecraft, these are the required materials to use a command block:

1 Command Block

Program the Command Block

First, you need to program the command block with a /summon command that will be used to build the castle. This /summon command will be run when the command block is activated.

So, stand in front of the command block with your pointer (the plus sign) on the command block and click on the right mouse button.

open command block

This will bring up the programming console for the command block.

console command

Now, type your command in the "Console Command" text box.

In this example, we are going to build a castle that is complete with 4 large turrets. We use various fill commands and setblock commands to build the castle.

IMPORTANT: Please do not copy our command block programs to another website or YouTube!

console command

When you are finished entering the command, click on the Done button.

Activate the Command Block

Now, activate the command block with the redstone device such as a lever, button, or pressure plate. In this example, we are going to use a lever to activate the command block.

open command block

When a player pulls the lever, the command block will be activated.

console command

Now you will see a tower of command blocks and redstone blocks appear. Then after a few seconds, the castle will be created next to you.
