“…We can classify the housing environment into two categories-dwelling internal (DI) and dwelling external (DE). As to the DI, the attributes include floor area, room layout, quality of construction, privacy, indoor environment [28,29]. Mohit and Mahfoud [30] found that elements of DI, especially floor area, correlate positively with residential satisfaction with public housing in Kuala Lumpur, Malaysia, where dwelling size was found to be an important predictor of residential satisfaction.…”

Affordable housing for the low-income population, who mostly live in slums, is an endemic challenge for cities in developing countries. As a remedy for the slum-free city, most of the major metropolis are resorting to slum rehabilitation housing. Rehabilitation connotes the improved quality of life that provides contentment, yet what entails residential satisfaction in such low-income situations remains a blind spot in literature. The study aims to examine the factors affecting residential satisfaction of slum rehabilitation housing in Mumbai, India. Here, the moderation effects of sociodemographic characteristics between residential satisfaction and its predictors are elaborated using a causal model. Data on residents' perception of the residential environment were collected from 981 households in three different slum rehabilitation housing areas spatially spread across Mumbai. The causal model indicated that residential satisfaction was significantly determined by internal conditions of dwelling resulting from design, community environment and access to facilities. Gender, age, mother tongue, presence of children, senior citizens in the family, and education moderate the relationship between residential satisfaction and its predictors. The need for design and planning with the user's perspective is highlighted to improve the quality of life.Sustainability 2020, 12, 2344 2 of 22 entails residential satisfaction in such low-income situations remains a blind spot in literature. There is a need to find ways to improve the housing conditions that take into consideration the satisfaction and well-being of the residents [7].When moving from slums to newly built high-rise apartment buildings (slum rehabilitation housing), the residents' physical living conditions were certainly improved. Little is known regarding their social and economic changes. Would the residents sustain in the slum rehabilitation housing in the coming years? This study aims to find out the residential satisfaction of the urban poor living in the slum rehabilitation housing in Mumbai (that is, how satisfied are the residents with the dwelling, building, and neighborhood overall), and its determinants. In doing so, the study explores the moderation effects of sociodemographic characteristics on the relationship between residential satisfaction and its proposed predictors. The goal is to derive recommendations for improving the existing slum rehabilitation housing under the slum rehabilitation program. The results can impact 900 million people including the 5.2 million Mumbai population who live in urban informal settlements or slums [8]. Additionally, the study contributes to developing approaches for sustainable urban renewal. According to Renigier-Biłozor et al.[9], a rating system shortens the time and brings objectivity in the decision-making process. So, understanding the factors affecting residential satisfaction is crucial for planning an effective and sustainable rehabilitation housing policy.The traditional mass housing design focuses on qu...

“…A comparison of thermal comfort and indoor air quality between the slums and SRA houses has in many instances shown slums to perform better (Lueker et al 2020, Malik et al 2020, Sarkar & Bardhan 2020a, 2020b. A satisfaction survey in SRA shows that more than 70 per cent of tenements are satisfied with the slum rehabilitation housing (Kshetrimayum et al 2020).…”

Like many countries of rapid urbanisation, Ethiopia has an acute low-income housing shortage. Ethiopia�s Integrated Housing Development Programme (IHDP) can be seen as an attempt to innovate low-income housing provision. Over 200,000 IHDP units have been built since 2005. Drawing from a Post Occupancy Evaluation (POE) survey in Amhara region, this article asks how the transition to high-rise has affected household practices and energy use. The POE survey shows low satisfaction among the residents, despite energy access and sanitary facilities. The new built environment compromises and contradicts established cultural practices, reducing the residents� well-being compared to previous living in more informal settlements where the dwelling had direct access to outdoor space and community. This means that the residents tend to view IHDP housing as transitional, disincentivising improvements in the environment or social networks. Further, the loss of ground connection causes domestic and cultural practices to move indoors, increasing energy demand and reliance on appliances. This paper argues that high-rise as the only typology for mass housing should not go unchallenged. If it is the only option, design standards should not be left open to interpretation by the developer and regulations should ensure adequate design, such as dual aspect, flexibility and privacy in floor plans, and design and designation of outdoor spaces. The findings question the idea of modernisation of housing as a linear process and challenge the literature on the compact city model as �the� paradigm for sustainable cities in Southern urban practice.

Architecture and planning play an important role in ensuring good light and ventilation to provide a healthy and livable environment. To investigate the strength of association between structural factors of slum resettlement colonies buildings and the burden of tuberculosis (TB), a questionnaire-based semi-quantitative survey of 4080 households was carried out in three resettlement colonies (Lallubhai Compound, Natwar Parekh Compound and PMG colony) with questions on architectural patterns, socioeconomic details as well as occurrence of TB in any member of the household. Computational modelling for Sky View Factor, Daylight Autonomy and Natural Ventilation in the houses of all three colonies was also performed. The results show that lower floors do not have access to sufficient light and ventilation in the living area. Occurrence of TB was strongly associated with lower floor of the house, closed or only partially openable windows, lack of exhaust fans as well as the built environment of the houses. The study also traced back the poor conditions of light and ventilation to the relaxations in development control regulations given to rehabilitation buildings. The study recommends better planning and architecture measures to bring improvements in housing and avert a public health crisis.
