This paper examines the visions and the roles of community training centers (CTCs) in community development and housing provision in developing countries from the perspective of assisted self-help housing. It reviews a Korean community center that contributed to community-led self-help housing for low-income groups in the 1970s. It also reviews a few notable CTCs from India, Uganda, Nepal, and three countries in Central America to examine the functions and contributions of the CTCs. It was found that CTCs play a central role in community empowerment and the production of affordable building materials receiving technical or financial assistance from non-governmental organizations (NGOs) and governments. The paper makes a compelling case for CTCs by drawing on these exemplary cases to provide a development model that has the potential to facilitate the improvement of the living environment in developing countries.Sustainability 2020, 12, 2952 2 of 22 problem for low-income households in emerging cities with greater effect when it matches with appropriate external assistances.The hypothesis of this paper is that a community center has a significant role in self-help housing and the effect through this is boosted when this is assisted by external organizations in terms of building technic and finance. This paper examines the functions of a community center in community development and housing provision from the perspective of assisted self-help housing from housing development practices.

We use CTCs as a place or space for communal use, such as meetings and workshops, the function of which can be extended to a place for training or production for self-help housing.Park et al.[5] suggested a comprehensive community center that has multiple functions as follows. A CTC can play a central role in involving the residents of settlements or development areas, both in upgrading and streamlining collective housing and home-renovation processes. It may also engage in the provision of temporary 'transit houses' for those who are waiting for a new or renovated house, and/or are participating in a mutual house building or renovation process. A CTC can also have evolving and dynamic functions. Initially, it can operate as a community space for group meetings, such as education and training seminars held by NGOs, and then it can move on to function as a normal community center or neighborhood facility. The presence of a CTC can stimulate households to participate in neighborhood development and the construction of safe affordable homes. The sense of "belonging" or ownership over communal facilities and the houses can grow, and this is beneficial for future owners and residents.
