This 20′ interior diameter, 314 sq. ft. design is my proposed solution for houses that need to withstand repeat hurricanes. See How to Build the Strongest Buildings That Can Last Centuries for more details. Features include: lexan windows with removable window and door shutters, monolithic geopolymer slab floor that’s integrated with the walls, build on high ground, plastic mesh that won’t rust, geopolymer plaster both sides, geopolymer pumicecrete or geopolymer perlite fill. Integrating the slab and dome and building on a rubble trench is ideal for seismic zones. In an earthquake, the building would slide back and forth somewhat like an upside down cereal bowl on a kitchen table (meaning the whole house remains intact as one shell).

The design will have to be tweaked for individual homeowner needs, and some details worked out with the engineer. Note how a woodstove is shown to reach a wider audience, even though it’s probably not needed in Florida. The woodstove could be replaced with an emergency water storage and filtration system, etc. A fold-out bed saves space. Please email me and we’ll work out the details to fit your needs.

This Emergency Shelter design is the result of collaboration between Kelly Hart and Owen Geiger. We came up with this design in response to a plea from aid agencies operating in Pakistan after the 2005 earthquake there. The challenge was to provide quick, safe, decent shelter with minimal tools and supplies to sustain life through the winter. Access to remote areas was extremely difficult, since many roads had been destroyed or blocked by landslides. Because of these and other difficulties, and the fact that winter would create a much more dire situation, fast easy-to-build temporary shelter seemed most appropriate.
