Abstract:

Studies identify that architectural design characteristics affecting design simplicity enhance core housing affordability. Effect of this attribute for affordability improvement, crucial in establishing design strategies for affordable low-cost urban homes, is lacking. Study examined this effect in Anambra State of Nigeria, using mixed method approach (primary data sourced from personal interviews, and questionnaire on 242 sampled residents from a 540 population. Using Kruskal-Wallis test and Spearman’s Rank-Order correlation for analysis, all prototypes were found non-affordable, with p-value of 0.000 for significant variation for affordability. Significant relationship, strong and positive (p-value, 0.000; correlation coefficient 0.778), was established between architectural design characteristics affecting design simplicity and affordability. Recommendations for improving core housing affordability include: minimal floor area for initial unit (studio apartments for households earning below N161, 000 monthly, 1-bedroom and 2-bedroom prototypes for those earning between N161, 000 and N200, 000); simple geometric plans; and local building materials for roof covering.
