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

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