This design is not my original creation; it belongs to SacredRedstone, and I encourage everyone to visit their YouTube profile via the provided link.

While not the fastest, this door is the most compact 3×3 piston door achievable in survival mode, utilizing only 56 blocks. A slightly smaller design exists, but it relies heavily on entities and is quite complex to build, making this classic design a more accessible option for all survival players.

Survival or creative?

This build is not survival-obtainable as-is. It contains Structure Block, which cannot be collected in survival – paste it in creative, or substitute those blocks.

Moving parts

It includes Comparator, Dropper, Observer, Redstone Lamp, Redstone Wire, Repeater, Sticky Piston, so check the mechanism still works after pasting – redstone state and item-container contents do not always survive a paste.
