The organised self-help approach successfully enhances urban low-income earners' (LIE) homeownership in some developing countries. The technique can enhance urban resilience for sustainable LIE homeownership. There is a paucity of studies concerning sustainable homeownership for Nigeria's urban LIE through a self-help approach. The study investigated the housing needs of the urban LIE via organised self-help mechanisms and how the same can enhance urban resilience for sustainable homeownership in the Ancient City of Benin, Nigeria.

Given the unexplored nature of the issue, 20 face-to-face interviews were conducted with experts and analysed through a thematic approach.

Findings identified eleven main barriers faced by the urban LIE. This includes the absence of government housing policy, funding frameworks, urban land scarcity, high property development costs, naira devaluation, high-interest rates, inflation, bribery and corruption, lax mortgage sub-sector, high cost of infrastructure, and government bureaucracy.

This study will contribute to pioneering the role of organised self-help mechanisms in urban resilience for sustainable LIE homeownership in developing cities via a qualitative approach. Also, findings would significantly contribute to developing countries' sustainable housing and urban resilience literature.

Housing transformation is not part of the Ethiopian urban housing policy, but it is a reality for city dwellers. The objective of this study was to find out what, why, and how aided self-help residents transformed their core house in Bahir Dar city. The focus was specifically on the transformations that resulted in changes to the floor area.

The case study research design is ideal for empirically examining socio-physical dynamics. The study employed three aided self-help housing cooperatives as case studies in Bahir Dar city. Information was gathered from cooperative members, committees, relevant government bodies, and the physical environment through field observations, interviews, photographic surveys, and questionnaires.

The findings showed three types of housing transformations that resulted in a change in floor area and are influenced by the building features of the original core house, motivation, and participation of residents. As a result of the housing transformation, residents became housing producers and suppliers, and their neighbourhood changed into a more socially and functionally diversified settlement.

The findings of this study have practical implications for policy makers to institute mechanisms that help planners and architects in preparing plots of land for residential use and in designing housing typologies. The findings will have an impact on the housing policy of Ethiopia.

The findings of this study will impact planners and architects when it comes to preparing plots for residential land use and designing housing typologies. In addition, the finding will have an impact on housing policy of Ethiopia.

The study of the resident’s housing transformation that brought floor area change provides further insights on the consideration of housing transformation as a housing production and supply strategy.

The purpose of this study is to inform policy and contribute to the existing literature on low-income housing.

In this study, a case study approach was adopted, and data were collected through secondary data collection that is literature survey and through empirical data collection by conducting face to face interviews and survey of key stakeholders, citizens, and government authorities, and in some cases supplemented by on site photography. The data collected from the field was analysed using quantitative and qualitative techniques. The questionnaires were coded for scientific analysis of data. The information was presented in a structured way that permits for in-depth analysis of the data.

In this study, many paradoxes were noted defying common sense, but nonetheless, they require a solution. It has been concluded that, while efforts to improve settlements and anticipate future ones are becoming more common, the desire for eradication persists in many towns in Botswana.

The major limitation of this study is that it was done during the period of COVID-19 induced movement restrictions. As a result, the preferred face to face interviews with key informants were not possible.

This research informed policy on low-income housing in Botswana. The Government of Botswana can use the findings of this study to formulate policies which help in alleviating challenges currently faced in practice when implementing low-income housing projects. The concept of low-income housing has been adopted by many developing countries including in Africa. As such, results of this study can also be applicable in other developing countries where they can be used as a starting point for evaluating the success of policies and the practice of low-income housing.

This work made original contribution to knowledge by putting the plight of housing the urban poor in Botswana will in perspective.

Swaziland is one of the countries with the highest Human Immune-deficiency Virus (HIV) rates in the world. Consequently, the increased need for care and support for people living with Acquired Immune-deficiency Syndrome (AIDS), as well as orphaned and vulnerable children, is unprecedented. The response to combat the HIV epidemic has been evident in many areas as the country continues its fight against the HIV epidemic. However, efforts to provide care and support - including Anti-Retroviral Therapy (ART), management of opportunistic infections, and community home-based care - have, so far, largely stemmed from the health sector. Housing care and other non-medical support is continuing to lag behind. Lack of proper housing is one of the deprivations suffered by orphaned children and people living with AIDS, which predisposes them to attacks by opportunistic infections and other vulnerabilities and disrupts the continuum of care, whilst at times denying occupants the required privacy.

This paper focuses on creating an understanding of why housing care and support for HIV and AIDS affected is lagging behind in Swaziland. It suggests cultural, economic, political and policy issues as the underlying reasons for this, and, therefore, concludes that there is need for bold policy reforms in these areas. In order to create a proper framework for such reforms, the paper reviews the following:

1. The national housing policy's implications on the care and support for people living with HIV and AIDS and the orphaned and vulnerable children; and

2. The current human settlements related responses to HIV and AIDS in Swaziland's rural, peri-urban and urban areas.

In this context, urban development planning paradigms and the extent to which HIV and AIDS is being integrated into the development plans are discussed.

The Nigerian Government has been left behind in the planning of homes for the senior citizens as they are aged and retire from service. The possible outcome is untimely death of many because of contagious illness associated with the dilapidated environment in their abode. Hence, this paper attempts to investigate the hindrances of home ownership faced by senior citizens and proffers possible policy solutions.

A phenomenology type of qualitative research was adopted and 30 participants were interviewed. That is, ten from four different state government agencies and 20 senior citizens using purposive and snowball sampling techniques and data saturation was also achieved. The data derived were analysed using MAXQDA 2018 and through a thematic analysis.

This paper found that Nigerian low-income senior citizens (LISCs) who owned houses lived more stable well-being. Whilst the level of home ownership was completely dissatisfying as failed mortgage finance, corruption in the pension scheme, relaxed National Housing Policy implementation and inadequate senior citizens’ home ownership policy were identified as the encumbrances.

This paper is limited to exploring the root cause of LISCs’ inability to gain home ownership and proffering possible solutions. Future research is needed to use relevant information in advancing home ownership policy for the low-income groups across the states in Nigeria and other developing countries.

This paper recommended that government should impose housing construction on three acres and above, mitigate corruption, establish special housing loan scheme for senior citizens, sustain rent-to-own policy and land subsidy in cities to enhance senior citizens’ home ownership. These recommendations form part of the paper's practical implications.

This paper demonstrates that existing housing policies are yet to consider the senior citizens regarding enhancing their home ownership status.

Construction practices used in the development of self-help housing and upgrade of informal settlements are believed to have negative effects on the natural environment. The purpose of this paper is to examine this idea by conducting a study on purposely selected informal settlements located in Mbabane, Kingdom of Eswatini, to determine the environmental sustainability of construction practices used in these areas and to offer an approach that can mitigate the environmental degradation witnessed in informal settlements.

The study comprised of three major components – literature review, situational analysis and research output. A literature review informed the extent of the problem and served to identify categories of assessment. A situational analysis of construction practices in informal settlements was done through the use of a structured checklist tool. Pattern matching was used as an analysis to evaluate the environmental sustainability of the identified construction practices.

Empirical results indicate a lack of environmental sustainability in the identified construction practices used. The challenges identified included the wrong choice of building material, inefficiency in energy use, a threat to biodiversity, poor planning and a lack of construction control measures. The research output was a framework encouraging affordable, sustainable and regenerative construction practices believed to be a viable solution to the environmental challenges within informal settlements. It was concluded that current construction practices used within informal settlements lead to negative environmental effects.

The framework offered in this study is believed to mitigate the negative effects on the natural environment in informal settlements.

Customization is a paradox in architecture, providing necessary modernization for buildings but potentially damaging their architectural integrity. In this paper, the authors introduce the Inhabitant-Driven Customization approach for avoiding this paradox; this approach lets inhabitants design the customization from options created by architects that safeguard architectural rules. As a first implementation of the Inhabitant-Driven Customization approach, the MyChanges tool is presented. The authors assess whether the approach avoids the customization paradox by a qualitative stakeholder evaluation of the MyChanges tool and by a comparison of the Inhabitant-Driven Customization approach with existing approaches to housing customization.

MyChanges is a shape grammar-based design tool developed to enable inhabitants of the Álvaro Siza Vieira Malagueira housing complex to customize their houses in accordance with the architectural language of the complex. In this study, the authors qualitatively evaluated MyChanges with architects and other professional stakeholders. MyChanges is used in this paper to assess if the Inhabitant-Driven Customization approach avoids the paradox of customization. The initial reception of MyChanges produced diverging outcomes, suggesting that Inhabitant-Driven Customization is also unable to avoid the customization paradox. For analyzing this possibility further, this paper describes the main existing approaches to housing customization, including the Inhabitant-Driven Customization approach, formulates nine conditions for these approaches, and provides a qualitative comparative assessment of the approaches.

The customization paradox is demonstrated in the outcomes of the interviews with professional stakeholders on the MyChanges customization tool for the Malagueira housing complex. An argument is given that makes plausible that the Inhabitant-Driven Customization approach avoids the customization paradox by creating a co-design process in which inhabitants and architects alternately shape customization.

The originality of this paper lies in the introduction and discussion of the paradox of customization in housing. The paper identifies the conditions advanced in architecture for assessing housing customization approaches. Additionally, the authors propose a new customization approach and a design tool that to a large extent fulfills those conditions and avoids the customization paradox.

The purpose of this paper is to explore opportunities and barriers to using lean construction to address issues related to the value, quality and scalability of affordable housing production in Latin America.

This paper presents a case study of a housing developer in Ecuador that used lean construction in the design and construction stages of an affordable housing project. The study describes how the developer addressed operational challenges derived from implementing a customization strategy and analyzes qualitative and quantitative data to assess the outcomes of lean initiatives.

The developer reduced cost and delivery time without sacrificing consumer choice. However, the economic and policy conditions worked against the benefits of lean construction, demonstrating the importance of the regulatory context in facilitating or inhibiting lean initiatives and construction innovation.

This paper focuses on conventional means for new housing construction. Self-help and upgrading are not covered.

The operational challenges described in this study, as well as the innovative ways to deal with them, are beneficial for practitioners seeking to improve the quality and efficiency of affordable housing construction.

This paper advances knowledge about how to increase value and quality delivery in the built environment which may benefit low-income families.

This study bridges construction innovation and housing policy, discussing the potential of lean construction within the policy and regulatory environment in which affordable housing takes place.
