Techno-Economic Analysis of Timber Modular Housing Solutions in Southwestern Nigeria

The study assessed firms’ investment and operational capabilities, technological specifications and economic viability of timber modular housing development in Southwestern Nigeria. The study targeted Oyo, Ogun and Lagos States due to housing deficits and concentration of building and engineering firms in the States. An Infrastructure planning framework was employed for the study. Questionnaire survey was used to collect data from housing/infrastructure ministry officials and private-sector built-environment construction & engineering professionals in the study area. Results indicated that the predominant technological specifications for detached timber modular houses were 120 ft × 120 ft (50%), 60 ft × 120 ft (37.5%), and 60 ft × 60 ft (10%). The economic viability assessment revealed Present Worth (PW) and Annual Worth (AW) of ₦220 and 265.5 million respectively, indicating financial feasibility of timber modular housing development. The study concluded that timber modular housing development in Southwestern Nigeria is both technologically feasible and economically viable, and could serve as a sustainable and scalable alternative housing solution for the region.
