This is my first working prison (all others ended gloriously). I purposely went small and tried to avoid it being too symmetrical. I need to work on a more elegant way to arrange the prison blocks so they are away from the staff locations. Keeping the prisoners out of the kitchen and having metal detectors in the hallways to the showers (shower first thing in the morning on the regime) really cut down on the random stabbings.
Running the pipes and electrical along the paths and through halls and doorways works well. I ran out of power so I had to start another power grid and having the power cables arranged this way made it easy to add a new generator as you cannot have 2 generators on the same grid. Planning to go with 2 generators on my next prison right off the bat, one just for the cell blocks and one for the rest of the buildings (adding more if needed).
Planning on creating a "Super Max" this weekend if time permits.
