The global housing crisis, exacerbated by rising construction costs, land shortages, labour limitations and even climate change, has underscored the need to experiment with designs to deliver quality accommodation. Pre-fab construction technologies present a promising solution, targeting these problems by reducing construction time, material waste, and overall expenditures. This paper aims to explore the potential of modular housing as a key strategy for improving affordability and enhancing the comfort of the inhabitants of residential developments, with a focus on using different types of solutions.
The paper analyses the application of the three main types of modules, previously defined by the author - construction, spatial-functional, and planning module through several examples. Their flexibility, adaptability and contribution to the construction process is studied. Their advantages and limitations are evaluated. The study employs a qualitative methodology, including a review and comparison of case studies, to define several key findings highlighting that modular construction significantly reduces construction timelines and labour costs, with each type of module offering distinct advantages for different housing needs. However, challenges remain in terms of size of single units, customization, integration and blending with the existing built environment, as well as the amount of initial investment.
The significance of this study lies in its ability to demonstrate how pre-fabrication for housing can serve as a cost-effective and sustainable solution to the growing demand for accommodation, especially affordable one. By highlighting the practical applications and limitations of different module types, the study provides valuable insights into how modularity can be applied to maximize their effectiveness in addressing the contemporary residential crisis – both in terms of affordability and lack of housing due to different factors.
