"The paper describes the transfer process of a population from an environmental protection area to a new location with the cooperation of a technical support program. New houses were built through the action of technical aid in the form of an automated house design program and further technical information interaction with self-builders. Houses were evaluated as to satisfaction and their environmental comfort conditions. In developing countries and particularly in Brazil, low income population groups often occupy vacant land close to urban areas with good infrastructure of transportation and job opportunities. These areas are often under environmental protection, and therefor residential building activities are illegal. In many municipalities these so-called urban invasions fall under the scrutiny of environmental laws and the population is forced to new locations through government supervised programs. This paper described the transfer process of one of these groups of populations in the region of the city of Campinas, in the State of São Paulo, Brazil. The local government provided a new area for subdivision and organized the distribution of residential lots per families. The program further offered the option of house constructions through a minimal house "kit", called "COHAB-Embryo" or the assistance of a technical aid program devised by a research group of the State University of Campinas. Houses were to be self-built in both cases. The Kit however supplier builder with the building materials on site."
