Background: After the spread of infectious diseases, people stay at home as a shelter space to be safe and sound. Current homes and work spaces have shown not to be a good environment for health and hygiene. During different crises of infectious diseases, architects and designers analyze the needs for change and evolve of environments to achieve a suitable design that prevents the spread of pathogens.
Objectives: This proper design should help improve people's living standards and mental health in terms of functionality and environmental psychology.
Methods: In the traditional architecture of some countries, such as Canada, Japan, and Iran, the vestibule has provided some possibility of separating the external and internal space. The design of the intermediate space with the appropriate scale of today's buildings at the entrance can create a filter between the indoor and outdoor environments by dividing these spaces.
Results: The use of intermediate space by modern technology can prevent the transfer of viral infection into the interior of the building. This can be done by removing the virus from clothes, changing or covering shoes, disinfecting equipment, separating infected items, and creating proper ventilation in the intermediate space so that microorganisms cannot be transferred into the safe environment.
Conclusions: In this paper, we looked at the architectural design in a new light to have a healthier life and more security, by inspiration of the patterns in traditional architecture and the human body.
