Aboveground Home Shelter is a 1980 civil defense guide published by the Federal Emergency Management Agency (FEMA) that provides detailed plans and construction guidance for a reinforced aboveground fallout shelter designed for family use. The shelter was created for homeowners who either prefer an aboveground structure or cannot build underground shelters due to issues such as high water tables. While the document acknowledges that underground shelters generally provide better and more economical protection, it demonstrates how a properly reinforced aboveground structure can still offer substantial protection against fallout radiation, hurricanes, tornadoes, earthquakes, and limited nuclear blast effects. The shelter is designed to accommodate up to six adults and can double as a workshop or storage shed during normal everyday use.
The guide provides highly detailed engineering and architectural drawings, including floor plans, elevation diagrams, wall sections, roofing details, ventilation systems, and reinforcement specifications. The structure is primarily constructed from reinforced concrete blocks or poured reinforced concrete with thick walls and ceilings designed to meet FEMA fallout shelter protection standards. The document explains important structural considerations such as wall thickness, reinforcement spacing, frost depth requirements, ventilation, roof loading, and proper material weights needed to achieve effective fallout shielding. It also discusses additional reinforcements needed in regions prone to hurricanes, tornadoes, or earthquakes.
Several alternate design options are included to help homeowners blend the shelter into residential properties. These alternatives include adding windows with removable shielding blocks, using brick facades for improved appearance, attaching the shelter directly to an existing house, and installing flat built-up roofing systems. The shelter is intentionally designed to appear similar to a normal utility building, helping it function as a practical multi-purpose structure rather than a dedicated bunker. The document also explains how airflow is maintained using natural convection ventilation and provides recommendations for electrical lighting, branch circuits, and interior comfort improvements such as damp-proofing and vapor barriers.
In addition to construction diagrams and technical notes, the guide includes a full materials list covering concrete quantities, reinforcing steel, masonry blocks, lumber, roofing materials, ventilation screening, gravel, vapor barriers, and hardware. The document serves as both a civil defense preparedness manual and a practical construction reference for creating a hardened aboveground emergency shelter capable of protecting occupants from multiple disaster scenarios while remaining useful as part of normal daily life.
