For my brand new server, me and my team are creating a few buildings.
The goal of these buildings are to be at human scale. We don't want to create huge empty structures just to have monuments. They'll be fully furnished and have a real utility.
We are curently using Spigot 1.7.10

This is a 3 stories fully furnished small prison.

There are 3 levels.
First level... 2 :) This is the guard room. Accessible by outdoors stairs. Fully furnished with all the confort to keep the prisoneers.
Next, level 1. This is the main cell with a bit of confort. Aproximately fresh water, a bed, a place to write and an other to eat. And light...
Finaly, level 3. This cell is really small. The extreme punishment. Just a stone bed and a small place to sit/write. No water, no food. Just a cell to wait for death...

On the server, the prison is protected with worldguard to disallow players to break any block. The players are teleported in the first or third level according to the decision of the moderators.
