This is my current design on a Fallout Shelter. This particular design will be constucted entirely underground and lay right below the freeze line. The walls are constructed out of filled cinderblock, the floor will be cement as well as the roof.

There are two entrances / exits.

The first entrance / exit will be masked inside of a workshop.
A large mock furnace will be constructed over a hole in the corner of the workshop. The hole will be the entrance to the shelter. To gain access one will have to open the furnace door and step inside, once inside there will be a man cover on the floor, lift the man cover and you will have access to the shelter.

The second entrance / exit will be on the other end of the shelter.
A mock power station will be placed over the entrance. The entrance will be entering one of the electrical panal doors. Once inside the panel there will be access to the shelter.

Here is the Floor Layout of the Shelter. It has seven rooms. The smaller six rooms will be used as storage and utility rooms. The main room will be used as sleeping quarters and the mess hall.



The Mock Power Plant. The center unit will be hollow, the door on that unit will lead you to one of the entrances / exits to the shelter.





The workshop. This is the other entrance / exit to the shelter. Within the workshop will be a mock furnace that will lead undergound.
