Carter Williamson’s Emergency Shelter–also known as “Grid”–is based on a system of a standard 2.4-meter material lengths and truck-load capacity. These standard lengths allow it to be flat-packed and shipped via truck to the location it is needed. Upon arrival, the materials are unloaded and easily assembled by four unskilled workers in less than a day. To maintain a solid foundation on uneven terrain, the shelter makes use of inverted Acrow props, which are traditionally used for scaffolding. In this case the telescoping feet can accommodate for differences in height and devastated locations.
The shelter features a large open floor plan with a mezzanine loft for sleeping. Barn door-style window shades open to allow for natural ventilation and can be closed to protect from inclement weather. The roof collects rainwater in two 950-liter cisterns on the back; a solar hot water system makes hot water; and a 1.5-kW photovoltaic system generates off-grid power. A deck can be attached to the house to provide extra space as well as a spot for an outdoor shower and a composting toilet. Carter Williamson’s design is also modular and the shelters can be combined in large clusters to aid large groups of people.

What is the approximate cost of these shelters? They would make great little get-away cabins in rural areas.
The product still has to be built and shipped. In a tropical environment, this design would deteriorate quickly. I personally favor Reactive Powder Concrete (self compacting, non-porous, ultra high strength, good tensile qualities and can be made luminescent) Quonset huts with tubing cast into the floors and walls for; water heating and cooling, high pressure forced air heating and cooling, phone, electric, cable, etc. Solar cooking, water heating and lighting is an absolute necessity. Make them so clay can be placed on top with a good soil on top for farming. Basically, 5 cubic meters of concrete for a 16 sq meter with 8 square meters shaded or a 20 sq meter home with 4 sq meters shaded, 2 front and 2 in the back.
