Minecraft – How to make a 2×2 piston door that is flush with both the inside and outside walls with no visible redstone

minecraft-java-editionminecraft-redstone

I've been trying to figure out how to create a 2×2 piston door that is flush with the wall on both sides and has no visible redstone (from either side of the door at any point). This would preferably be activated with a button toggle from either side and work ideally in vanilla Minecraft 1.7.10. I have not managed to figure this out myself so I thought I would ask here. My assumption is it would need to have the pistons be powered from below but I'm unsure how to go about it.

Sound's like you're asking about a hipster door, seen in this video by Reversed Gravity. The idea of these is that everything is flush with a 1 wide wall, where all the restone is beneath the floor. This design is showcased as 1-wide, but it can be expanded infinitely due to its tileable nature

As far as I can tell, this is the most recent and compact design, but feel free to correct me.

Edit:

As per Fabian's request, here's a screenshot with a slightly modified design so it's 1.15 compatible:

Two things to note:

  • The red arrows on the blocks are a tweak from a texture pack, they are observers with the arrows telling you which direction they should be facing. The same with the sticky pistons
  • The observer facing down on the bottom left has a piece of redstone dust on it, this is a modification of the original design because of a change that stopped powered blocks from updating observers
