Build Echo

Build Echo is a Minecraft Bedrock add-on for repairing player-built structures damaged by creeper and TNT explosions.

The add-on records supported blocks placed after it is activated. If an explosion destroys those blocks, cyan holograms appear in their original positions. The holograms preserve supported shapes and states such as stair direction, slab position, door orientation, fence connections, rails and redstone direction.

Look at a hologram to see which block is required. Hold the matching item and interact with it to restore the block. The item is removed from your inventory when the repair succeeds.

The Echo Core shows the total materials needed and can restore multiple blocks using the materials currently available in your inventory.
