So a server I frequented for awhile shut down the other day, but one of the players on there started his own server that acts as sort of a spiritual successor. I've been playing on there for the last few days and have constructed this building, the external part of which is based loosely on the head of my Minecraft skin:

The outside.

Standing at the top of the steps with the doors open. I was originally going to have the inside open, but the wiring for the door took up way too much space so I scrapped the idea. Turns out I enjoy weaseling redstone into tight spots.

Hub room. Players entering from above fall out from the hole in the center of the ceiling and pass through the quartz structure, which is filled with water to negate any fall damage.

Just finished this half of the farm before posting. Button turns the water on and off to harvest the crops and push them into hoppers, and the lever pulses a dropper below the chests to fill them with whatever was collected.
