**5. Conclusions**

Traditional architecture in Indonesia has been designed and maintained following the principles of sustainability. Such works of architecture avoid fabricated materials (and the pollution they cause), relying more on natural materials such as bamboo. Structurally, these works are earthquake-resistant and suited to their particular environmental conditions, having been designed and revised over generations through responsive contextualization. Likewise, these works provide comfort for their inhabitants even as they make optimal use of natural light and ventilation. To implement the principles of sustainability in modern architecture, ancestral and traditional approaches must be considered. Although these designs are uniquely suited to their particular contexts and functions, they all embrace the principles of sustainable architecture.
