This may not seem like a great build, but I just wanted to post this because everyone seemed to like it alot and have said it was the "most fun Jail RP" they have played in. Please note that this was build a while ago and I am a much better builder now. Here are some pictures of most of the building:

This is obviously the yard. Guards are allowed in, but it is hard for them to get in and to get out because the door is Prisoner team only.

This is the main gate. There is a 15-25 second delay on the gate opening after you start the computer.

This is a storage room, not much, but there is a hidden weapon in here.

This is the 2 jail cell floors. All the cells are the same except for ways out and hidden weapons.

One of the cells. Looks simple only because real jail cells are simple.

This is the guards spawn room. There are 5 different items, 1 is obviously required. There are cameras on the right to basically the whole building. Prisoners CAN get in here, my favorite strategy is waiting for a guard to come out and then slipping in and grabbing all the weapons.

This is obviously the bathrooms. Prisoners only because of too many people complaining about privacy (-_-).

This is the messhall. The "Guards Only" ladder is just a door at the top that opens up to a weapon. If prisoners are seen up there or on the ladder, they can be sent to Solitary Confinement, or just killed.

Not much to see here. Well this is ALL you will see in Solitary Confinement. Gets to you right?
Thats all. I guess I will be hosting this for a little while. It would be called:
"iBlox's Old Jail RP". If you have any questions about anything, please ask.
You may also rate the build x/10. I don't care what you rate it because it's old.
