The Best Underground Shelter

The Sea Egg as it is called is designed by professional boat builder John Glennie - based on his experience as a yachtsman who sailed 30,000 miles in many stormy seas.John also survived 119 days in his upturned trimaran the Rose-Noelle after it was capsized by a monster rogue wave in the Pacific Ocean. This shelter can be built by two people, with some additional help during concrete stages (shotcreting). The plans come with full instructions including multiple plan views and photographs. PLUS there is personal email support available at all times. Plans cost $750. .....
