Protection from high winds like those in tornados and hurricanes require:
— A low profile.
— Small eaves and no porches, or heavy built ones of reinforced concrete or steel.
— Deep anchoring footings.
— One piece construction.
— Strong walls, doors and windows.

Some of the features applied to our SAFE-HOUSE will make a house virtually immune to wind damage. Special attention has to be given to windows and doors, with 1/4 inch steel being the minimum acceptable protection in a tornado area. Our pyramid is designed for 500 mph winds minimum, something that only an explosion at close range can create. Some companies are out there selling what they call "hurricane windows and doors" that are faulty and will fail in a worst case scenario or even in a CAT 4 hurricane or F4 tornado and i wouldn't want to be caught on one of those in a CAT5 or F5. All that has to happen is a heavy object to be projected against a window or door and there goes your house. Roofs should be solid concrete or welded 1/4 inch steel plate, with no tile or easily peeled cover of any kind because they would be a liability in high winds.

Flooding protection is simple, just stay away from low ground, otherwise build tall with higher floors having all the necessary accommodations to sustain life for some time, even if the bottom floor is flooded. Needed to ensure survival in a flood is a separate water supply, self-contained sewer system, generator, and the ability to separate the electric system from first or lower floors. YES THIS IS SIMPLE, BUT YOU COULDN'T TELL BY LOOKING AROUND AT THE POORLY CONCEIVED HOUSES (READ DISPOSABLE JUNK) MOST LIVE IN.

Lightning protection requires a well designed system of air terminals and ground rods, but luck, location and prayer may help too.
