A guide to desig a temporary pre-fabricated transitional living space for post-disaster emergencies through the evolution of shape and Lego architecture.

Given the ongoing rise in the number of disasters and wars happening each year, there has been an increase in the number of people needing urgent shelter. This has made pre-equipped temporary shelters a growing concern in the fields of architectural and interior design. The idea of prefabricated construction emerged when Western countries needed to create quickly built housing to meet the residential needs that arose in those countries after World War II, including Japan.

Disasters have become part of our reality, posing challenges and obstacles for architects and interior designers. Therefore, the need for rapid construction of facilities has become crucial around the world.

By conducting a thorough review of previous research and architectural practices, "adaptability" and "recycling" were identified as two key characteristics of prefabricated temporary buildings in the post-disaster period. Despite the numerous examples of disaster recovery efforts around the globe, most of them have been disorganized and insufficient to meet the real needs of affected communities. While homes and public facilities may be rebuilt, they often lack the necessary suitability to house those in need.

Reconstruction after disasters can be seen as an opportunity to redesign the built environment in a manner that meets the current community needs, taking into account the natural environment and anticipating future risks. Accidents and disasters have the potential to push communities to reassess their situation and seek appropriate solutions that address their needs. In our current era, where we have access to accumulated information and knowledge from around the world over the centuries, we should be able to find suitable solutions to create a sustainable environment that meets the needs of communities.

This research aims to design a temporary living space for displaced people after a disaster, by using prefabricated buildings such as modular buildings and Lego architecture. Prefabricated buildings are considered one of the innovative methods that contribute to saving time and effort in emergency situations and natural disasters. This research is based on a model of separated architecture design, addressing the definition of modular buildings and the main components of Lego architecture. It starts from creative thinking and seeks to integrate relevant design methods and knowledge into a systematic solution.
