Case del Fe (Faith House) is a house built for the Hondurian Foundation for Rehabilitation and integration of handicapped people. This building does not feature a green roof. For pillars, Andreas Froese used vehicle wheel rims to create columns.
Campo Cielo, Honduras, 2004
Campo Cielo is a sort of club room for women realized in Tegucigalpa, Honduras, 2004 by Andreas Froese. It offers shelter for about eight people. The building has an integrated water tank which required that cement had to be used in order to protect the earth mortar from water.
Froese usually does not apply cement in the walls of the buildings, but rather relies on earth mortar to stick the PET bottles together (see for example also the Trivadrum Cerala in India on this page).
Haiti Eco Living Project – H.E.L.P.
After we finish up our prototype demonstration Earthship at the Grassroots compound in late January, 2011, we are taking what we learned from that and what we have absorbed from our time spent with the Haitian people and attempting to move forward with project H.E.L.P. – Haiti Eco Living Project. Groups of Earthships the Haitian people can build themselves that are absolutely sustainable. These Earthships are built using materials found in and around Port-Au-Prince.
Andreas Froese is a German active in Honduras, South America and who has developed a number of techniques to integrate PET bottles in building construction. For this purpose he started the company ECO-TEC in 2001 in Honduras. This company supports among other environmental issues the reuse of solid waste in architecture. Froeses’ developed building technique reduces the use of concrete in building to 40% of regular cost. The system uses the PET bottle as a brick, fills it with natural resources such as sand or mud, and sticks it clay and other locally produced garbage such as rubble and vermiculture. Froese usually employs people in social need which adds another dimension of sustainability to his approach.
In El Zamorano, Honduras, a house from 8000 PET bottles was constructed in 2003. The green roof in wet conditions can weigh up to 30 tons. Nevertheless, there are no extra reinforced supports other than the PET wall. This house is generally considered the first PET bottle house without the use of cement for the walls.
