“The Haitian National Congress (HNC) asked me to conduct training next May for bright and eager Haitian adult citizens who want to become entrepreneurs, nudge their country more toward functional democracy, learn problem solving skills and learn free enterprise practices that will increase their personal income. These trainees will then return to each of Haiti’s 10 departments to teach others about developing cottage businesses, managing money, establishing new markets, increasing vegetable production and more.

Haiti needs more housing stock. For the individual Haitian, owning a home and building equity in it is a way to better oneself financially. HNC is working with folks who have minimal income. HNC encourages them to build wealth which helps the country build a stronger economy. That leads to more jobs, more children getting educated, better health care, etc. To have value in the housing market, they need a house that is modern (plumbing and electricity), durable (earthquake and hurricane resistant) and of course, affordable. With a modern and durable house as collateral you can borrow money to start a small business. Lack of access to capital is a major barrier in the third world to individuals lifting themselves out of poverty. Earthbag houses are perfect. Hands on learning how to build an earthbag house will be an important part of the HNC training. The trainees will learn, and they will in turn train others in earthbag building. Modifications can be made in the field in response to local feedback.

Dr. Owen Geiger took my basic ideas, enhanced them greatly and developed an attractive plan. It is a durable and leak proof ‘core house’ with a multipurpose room (kitchen and living room), bathroom and bedroom. There is a covered, raised, and railed front porch for Haitian style outdoor living and for social gathering. Also, Dr. Geiger designed the walls a bit higher than 8’, dropped the ceiling slightly and put two ladder accessible lofts above. There are covered porches around the entire house that can serve as outdoor cooking, food preparation and work areas. They can also be easily converted into additional rooms. HNC and I are happy with this earthbag house plan that offers so much flexibility. The owners will have several options for sleeping, storage and work areas. While the disaster resistant core house remains the same, the lofts and porches allow each family to set up the house just the way they like it in order to meet their specific needs.”

Disaster Resistant Catenary Dome (click to enlarge)

Disaster Resistant Catenary Dome (click to enlarge)


Specifications: 314 sq. ft. interior, 181 sq. ft. interior loft, total = 495 sq. ft. interior, Footprint: 23’ diameter

Description: Catenary arches and domes are among the strongest forms in nature. This catenary dome is designed to withstand repeat hurricanes and other natural disasters. It is similar in construction to the Hemispheric Dome, but the Catenary Dome has a sleeping loft. Tilt-down stairs are shown, although you could make a single bathroom door and add a ladder to one side. This would give you more space in the loft.

Disaster-resistant hemispheric dome made with double ferrocement shells with insulating fill (click to enlarge)


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.

Designed to weather hurricanes and other extremes of ocean-front property — a perfect application for earthbags, which far surpass most other building materials in terms of hurricane resistance. This design also includes an optional cistern under the house for storage of roofwater.
