Underground below building bunker

Abstract

An underground below-building bunker has bunker quarters (1) positioned under ground (2) below a dwelling-related structure (3), such as a garage, a room or a hallway of a dwelling (4). A floor-entry door (5) such as a trapdoor, horizontal slide door or other through-floor entry leads to a vertical passageway (6) where a bunker door (7) provides entrance to a stairway (8) or ladder (9) to a bunker floor (10). A buffer zone of protection is provided in the vertical passageway intermediate the floor-entry door and the bunker door, which in combination provide a predetermined level of protection against foreseeable hazards. The ground below the dwelling-related structure has a depth at which enclosure structure (12) of the bunker quarters can provide protection against predetermined hazards. Air vents (15, 17) into separate portions of the bunker quarters provide safety redundance of air from safe-air sources (19). Outside communication with preferably a wireless phone (21), lights (22), storage (23), water (24), food (25), sewage disposal (26) and other features are provided selectively.
