The construction method is adjudged to significantly reduce building time and offers good economic value which are some of its key benefits over traditional construction methods. This study evaluated architects’ awareness level and adoption of modular construction method in Nigeria, in order to ascertain its application level towards providing prompt affordable housing projects delivery in the country. The study is a survey research that engaged a pragmatic research approach. Both qualitative and quantitative inquiry methods were employed to carry out the research. Qualitative inquiry method was employed to gather relevant data used to develop a structured questionnaire that was used to collect quantitative data. The questionnaire was distributed to a hundred architects who were randomly selected from a hundred architectural firms registered to practice in Lagos State, the most populous state in Nigeria. A total of seventy-one participants provided data for the study. The data were analysed with statistical package for social sciences (SPSS) software, version 21. The result depicts that majority (87%) of the respondents are aware of modular construction as an approach used in building construction, but just few (32%) of the respondents have adopted modular construction in the delivery of affordable housing scheme in the study area. In addition, it was found that modular construction for affordable housing projects is mostly adopted for its waste reduction, construction time reduction and cost saving benefits. The study concludes that though architects’ awareness level of modular construction method and its benefits is high in Nigeria, its adoption by the architects for prompt delivery of affordable housing projects in the study area is low. Hence, appropriate measures were recommended to enhance the adoption of modular construction method by architects to combat housing challenges experienced in Nigeria.

Though, the Nigerian government has at various times tried to implement different policies and programmes to tackle the problem of housing deficiency in the country, nonetheless, there has been an increase in the urban housing crisis in the country [2]. The high cost of materials poses a major challenge in the provision of affordable housing in Nigeria. Construction processes and the built environment also have great impact on the environment, human well-being as well as the overall economy. However, modular construction is a method that involves the use of pre-designed building units or parts that are constructed off-site, conveyed to site as components and assembled to form a building or structure. Modular construction method significantly reduces building time and offers good economic value which are some of its benefits over traditional construction methods [3]. To this end, modular construction is being preferred and used to delivery projects promptly and at good economic value in many countries. It is against this backdrop that this study evaluated architects’ awareness level and adoption of modular construction method in Nigeria, in order to ascertain its application level towards providing prompt affordable housing projects delivery in the country. To this end, two research questions were developed as follows: 1. What is the level of awareness of modular construction method among architects in Nigeria? 2. To what extent is modular construction method adopted by architects in Nigeria for affordable housing delivery in the country? Based on the research questions, two research objectives were formulated as follows: 1. To evaluate the level of awareness of modular construction method among architects in Nigeria. 2. To examine the extent to which modular construction is adopted by architects in Nigeria for affordable housing delivery in the country. The scope of this study is limited to Lagos State in Nigeria. The study was restricted to Lagos State as it is one of the most populous and continuously growing cities in Nigeria with a high rate of housing deficiency [3]. Currently, the state is experiencing rapid growth in infrastructural and building developments, which is attracting several construction professionals, including architects, from different parts of the country and the world to practice in the state.
