It's the real thing.
the building is grounded by driving an L extrusion stake at each of the four corners onto which the walls attach. these are braced with more extrusions bolted horizontally between the corners. the wall sections can be stacked ground up. the roof section is hinged to the wall section and is designed to be openable for venting. the weight of the roof and its cable controls, double as a tensioning system for the walls.
the wall modules can be used horizontally to create an at grade floor. water in the bottles acts as thermal mass to buffer against extreme temperatures. the ground should be excavated past the walls, leveled, and hard packed with sand. gravel is used to fill all around to aid drainage and the finish grade sloped away from the house. an above grade raised floor is also possible when skilled labour isn't available or in uses where the occupants must move the house frequently.
in situations where bottles must be supplied, i suggest that they be factory packaged and shipped with clean drinking water inside. water supply is not only a high commodity, it is also a necessity to sustaining a community. dehydration causes lethargy, headaches, diziness, and confusion . even mild dehydration reduces endurance and impairs concentration. being able to use the empty bottles as housing materials could justify the cost of importing water, making success in remote locations possible. the same applies to places where the ground water has been contaminated by surface runoff and nature needs time to detox. unclean water indirectly causes dehydration and affects daily performance in work.
convenient safe water is the best way to impact rural villagers in the developing world in a positive way. in these places, the men of the community are usually a combination of hunter/gatherers minding small agricultural plots of land where they grow crops that typically have been grown in their area for thousands of years. the women and children of the community gather water and firewood, wash clothes and prepare meals. If there is a rural school within walking distance, the children will attend up to about sixth grade. girls will often stop going to school before sixth grade if there is no private sanitation facility located at the school because of embarrassment due to lack of privacy.
there are life-changing health ramifications associated with providing water to a community that affects disease, hunger and poverty. providing a water source for an area of villages also impacts education, business opportunities and personal growth. it takes a lot of time for women and children to access water in many regions of the world. in africa, water can be many miles away and it takes time to walk that distance carrying a heavy resource such as water (weighing 8.3 pounds per gallon). even in developing countries that have a lot of surface water, villagers often must walk down to a stream that may be hundreds of feet below their village (or likewise up to a spring) and then must walk back to their village carrying water-filled containers up (or down) steep and dangerous hillsides. women and children can only carry 1 � 3 gallons of water (weighing 8 � 25 lbs) under ordinary circumstances so gathering water several times a day is often required. if clean water were made available at home, women and children would have substantial more time in their lives to allow them the time to pursue things such as an education and to be more productive, for instance by weaving products for sale. so besides impacting disease, hunger and poverty, providing a safe water source also opens the possibilities for higher education and business opportunities, especially for women living in the developing world. there is nothing that comes close to making a positive impact for villagers in the developing world as giving them a safe convenient source of water . housing may be a concern to some, but they already have temporary shelter. yet without health and vitality, they could never earn the $300 to buy the homes we are designing. doctors recommend a minimum of 4-5 litres per day for optimal health, so if a person saves their water bottles for a year that is at least 730 bottles. between 3 people that is already more than enough to build a house.
