Appraising Habitability of Affordable Housing Projects in Nairobi, Kenya

Abstract

The objective of this study is to empirically evaluate the habitability of three exemplary affordable housing projects in Nairobi, Kenya, based on criteria related to physical house qualities and architectural excellence. A 24-item questionnaire derived from a synthetic habitability measure was delivered to 92 participants, with data analysis conducted utilising the Severity measure (SI). The findings indicated that respondents primarily derived functional meaning from specific habitability variables such as circulation and access efficiency, locational factors, acoustic quality, and the suitability of height and density, whereas social meaning was predominantly derived from the capacity to foster interaction and the adequacy of privacy. Residents found diminished significance in housing resilience and the implementation of sustainable and renewable systems. Anova tests indicated substantial correlations between inhabitants' essential socio-demographic attributes and specific variables. The analysis of national and global housing standards was conducted using three checklists, while interviews with professionals in architecture, planning, and health were employed to evaluate the impact of the planning system on habitability. Findings can aid policymakers in identifying and prioritising the most significant aspects when formulating future housing plans in Kenya.
