Prefabricated house make costs lower
The concept of prefabrication in the construction process refers to the production of parts, parts, or the entire building in a factory, and then transportation to a construction site for rapid installation. Compared to traditional construction methods, prefabrication has many advantages, such as speed, construction accuracy, efficiency, cleanliness of construction, and cost issues in many cases. Considering that housing is a fundamental human need, whether providing housing for the growing urban population or for temporary or emergency residential areas on the most diverse scales, the construction of affordable and high-quality housing using industrial production methods has always been of interest to architects. From the past to the present, after many attempts, the question remains whether the popularization of prefabricated construction can provide solutions for more equitable housing.
By prefabrication and modularization, it is possible to build the foundation on site while also constructing other structures within the factory. At the construction site, the assembly process is fast and heavy machinery is usually used to lift the structure. Less construction time, greater predictability of construction progress, less labor demand, and less on-site waste, in contrast to lower final costs and earlier commercial ownership. With the advancement of design, processes, tools, and technology, costs will also decrease over time without sacrificing the quality of materials. As more processes are repeated, this can improve efficiency and significantly reduce long-term costs.

This idea is not a recent one. Architects such as Frank Lloyd Wright, Le Corbusier, Jean Prouve, and Walter Gropius have developed several projects in an attempt to effectively integrate housing construction with industrial production. Specifically, it is worth emphasizing the efforts made by Gropius in prefabricated construction. Gropius and Konrad Wachsmann's "The Dream of the Factory Made House" edited by MIT provides an overview of the experiences, achievements, and setbacks of the two German architects. The Packaged House system, developed by two architects, is a unique and eye-catching prototype that was developed after World War II and can be expanded or reduced as needed, but unfortunately, it did not survive commercially.

In the book "Bauhaus: novarquitetura" published in Brazil in 1929, Gropius quoted an interesting method to explore this topic: "Just like 90% of people today no longer order customized shoes, they limit their use of mass-produced products due to improvements in production methods. In the future, individuals will be able to order the most suitable housing from factories. Modern technology may be able to handle this task, but the economic organizations of the construction industry cannot. It still relies entirely on manual work methods and does not reserve fewer restrictions for machines.".

Although there are many companies producing prefabricated housing nowadays, as well as many cases of prefabricated housing, Gropius's prophecy has clearly not become a reality as he expected, especially in developing countries where construction is still highly manual and the industry is considered extremely resistant to change and technological integration.

But this situation has changed. There are two main types of prefabricated components: 2D and 3D. 2D includes pre sized parts and panels for easy transportation and customization; And 3D prefabricated components are three-dimensional structural systems that can be assembled on site, including other units and systems, usually including all installations.

The report "Modular Construction: From Projects to Products" points out that since 2019, "modular (or prefabricated) construction is not a new concept, but technological progress, economic demands, and changes in thinking patterns mean it is attracting unprecedented interest and investment. If this situation occurs, it will greatly improve the productivity of construction, help solve many real estate crises in the market, and reshape the way we build today.". The paper argues that recent modular projects have created a reliable record of accelerating project progress. Modular structures can increase construction speed by 50%, and with the right balance, they can reduce costs by 20%. This method also has the potential to save a significant amount of costs, although it is currently an exception.
