Families are subject to suffer from serious difficulties and unresolved problems at all levels incurring discordance and conflicts which result in some family members, notably children, to leave the house and seek resort and some social institutions such as children welfare institutions that provide an alternative to the family atmosphere.This study attempts to determine a child’s ability to cope on his new environment physically and socially. Besides, It intends to evaluate environmental conditions that contribute to the promotion of children well-being and to their positive adaptation living away from their original homes and families. This study hopes to provide as well recommendations for modifying the conditions in the children new environments. For this reason, we chose two types of Lebanese children welfare homes as a sample :1-- The social institutions which receive children coming from families which mainly suffer from socio-economical difficulties. Theseare structured in a way to receive as many children as possible where social workers look after the children at all levels. The landmark of the style of live in these spaces of transition (Lawrence, 1984) is collectiveness in all types of activities.2-- The Villages for children receive children who have to live away from their mothers (due to death, sickness, etc.…). Every village is a complex of ten or fifteen houses. Every house is built following a well established scheme of structural and interior design. In every house, a social worker (whom the children call mum) takes care of 8 to 10 children and of all the affairs of the house. The population considered in this study represents children ten to twelve years of age living in these two different kinds of environments :--- 95 children hosted by welfare institutions;--- 40 children hosted by S.O.S villages.The methodological procedures implemented in this study are based on a multi disciplinary approach which makes use of some research tools such as :-Visiting the children and observing these environments under the provided conditions.-Asking children to draw a house whereby, their drawings are assessed objectively using Maalouf ‘s scales (2003) inspired by barrouillet (1994) and Greig (2000).-Investigation by questionnaires (open/close questions).The results of this study reveal that away from their parental houses, these environments, though constraint, activated the children to express significant modes of behavior such as responses to territorial spaces (personal spaces), love / hate bonds, feelings of belongingness, avoidance, intimacy and sense of freedom. These modes of behavior are expressed by children in special ways characterizing each of these two environmental settings, Besides, the analysis of these results cast light on the major role of social and emotional climates (Moos, 2003) ; climate which enhance personal skills such as coping (Korpela 1992). fact, the social climate has a pervasive influence on the emergence of feelings of attachment (Feldman, 1996 ; Mc Andrew, 1992) to a place (home, home range, relatives homes).Our findings stand out by conveying a special concept called “Residential Social Hope“ after Maalouf (2003). During the congress we will expound this concept by setting out three processes that show how children lacking family support – living away from home – are able to develop positive relationship with their homes. The “Residential Social Hope” concept is evident in the welfare institutions but lacking in the S.O.S villages. It appears that when the children are kept assured being connected to their roots and that their first (parental) home does always exist for them to return to, they express certain and positive attitude reviewing their relationship with the members of their families and with their homes. Broadly speaking, this concept put the social climate in its significance and effect about the functional aspect (Robin 2001).
