This item is a large 3 room add-on, underground bunker. It is a furniture item, so it can be attached to a furniture floor node of any existing room. At time of developement, it loads properly. All nodes in this item (ceiling, floor, and wall) are assigned to be in the 900s, so as not to conflict with the nodes already in the room, (as long as the node counts in the room doesn't exceed 900). Using this node counting method enables imvu to load this item correctly with additional furniture items within it.
