“…In Central America, CTCs contribute to the upgrading of housing and habitats in association with housing cooperatives. In an investigation of 22 housing cooperatives in Central America, it was found that the cooperatives were founded on the housing model with mutual aid, a proven model of the Uruguayan Federation of Housing Cooperatives with Mutual Aid (FUCVAM), for solving a substantial part of the housing deficit in Uruguay [6]. The key features of such a model are affordability and quality housing, the use of group savings, joint actions and efforts, and common property in the form of land and homes.…”

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. This paper also investigates how low-cost housing production can be supported by the establishment of a community center, more specifically a community training center, (CTC) focusing on the relationship with NGOs and governments in technical, organizational, and financial assistance through this center. 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. A production unit to build materials and transit homes...

“…While perception on structural quality and soundness of LIH requires a full cycle analysis by structural engineers, a perception survey or opinion of residents/occupiers can also provide a good sense of the structural sturdiness of LIH as viewed by the occupants/residents. LIH envisages the conception and deployment of advanced and appropriate budgeting, cost reduction, building and construction techniques through use of locally available materials and the prudent application of skills and technologies without compromising the housing units' strength, performance and life of the structure (Bredenoord, 2017;Foong et al, 2017;Ganiyu, 2016;Holweg, 2007;Howell, 2011;Tam, 2011;Salem et al, 2006;Van Damme and Houben, 2018). Overall, approximately 10% of LIH RDP or state subsidised structures perceive such structures as either having structural defects or inadequacies with respect to walls and roofs.…”

The Oxford dictionary defines the word "blues" as meaning "a feeling of depression or deep unhappiness, gloominess, despondency, dejection and despair". The concept of low-income housing (LIH) and the notion of housing backlogs and deficits "blues" in South Africa is linked to a sub-optimal performing LIH sector in which slow turnaround times, slow service LIH delivery stock turnover and continued failure to reverse significantly LIH waiting list requirements persists across municipalities throughout the country. Coupled with the challenge and threat presented by climate change (CC) induced vulnerabilities for LIH with questions marks hanging with respect to the capacity and capabilities of both state and non-state actors to provide a sustainable CC resilient and insulated LIH sector in the country, so much that perceived feelings of gloom, despondency, dejection and despair start finding expression in respect to the ability of the housing sector to guarantee settlement resilience in this new climatic and socioeconomic environment. In this regard, exploring how existing initiatives such as alternative building Centre for Research on Settlements and Urbanism Journal of Settlements and Spatial Planning J o u r n a l h o m e p a g e: http://jssp.reviste.ubbcluj.ro This paper seeks to answer the following main question: "Does housing backlogs and deficits rhetoric constrain policy makers, decisionmakers, practitioners and experts from engaging in the implementation of transformative low-income housing projects and programmes in South Africa?". The aim and purpose of this paper are: (1) to contribute to the understanding of the concept of lowincome housing backlogs and deficits "blues" in South Africa. This is achieved through suggesting how innovative lean housing construction and development approach/models can play a "catalytic" role in the quest to redress low-income housing provision and delivery requirements; and (2) to argue that applied research and development of housing innovations in practice is critical in transforming the low-income housing sustainability agenda in South Africa and by extension in developing countries. The analysis is based on a critical literature review of housing approaches of low-income housing delivery, affordable strategies, policy implementation realities and discourses, low-income housing technology options, in addition to industry experience and own observation. This paper establishes the significance of considering up scaling the implementation of lean advanced construction techniques, use of low-cost building materials and fast-construction building techniques in responding to the growing demand for low-income housing provision and services in South Africa. The need to continuously monitor, evaluate and review the housing policy and regulatory setup relevancy in addressing low-income housing deficits and backlogs with the aid of a lean construction as necessary to improve low-income housing delivery deployment in South Africa.

“…Construction with industrial materials such as concrete or bricks is often considered as a plausible solution, but traditional materials and processes may offer interesting alternatives. Traditional buildings are commonly built by households and/or local communities themselves (Schroeder 2016;Bredenoord 2017), thus saving on labour costs. Therefore, material costs become the major contribution to the expense.…”
