Since industrialization, modern architectures seem to be superior to nature, but as a result of the interaction, various environmental pollution such as dust, waste, etc. has resulted in various damage such as ecosystem destruction, abnormal weather and fine dust. Beginning in the 1990s, diverse methods and continuous interest have been presented in the reflection of Western civilization and green architectural methods. Therefore, the purpose of the research is to provide an opportunity for us to think back about our future direction through the architecture of a fleet neglected by reckless development. Therefore, in this study, the ecological characteristics of traditional Korean houses are analyzed by deriving theoretical considerations and spatial characteristics of traditional houses through cases of straw and roof tiles that best depict the characteristics of traditional Korean housing. The ecological characteristics of Korean traditional houses derived from the conclusion are shown in environmental, structural, and technological aspects. First, Hanok is an energy-saving house suitable for the climate and natural environment. Second, energy dimension and living space were secured by minimizing external influences through deployment. Third, in terms of technology, the roof was secured with dirt and tiles, and a large load was used to push the column to design the seismicity. Through this, we hope that the consideration of traditional technologies will be the right stepping stone for future environmentally friendly future architectural methods.
