It is a well-known fact that humans harm the environment during the endeavors they do to fulfill their needs. It can be stated that adverse results are mainly related to creating built environments and the mechanism of current construction industry has a major role. This linear process, which starts at the end of design and continues through the aftermath of demolish of the building at the end of its useful life, has been gradually destroying the natural environment in a repetitive cycle of construction and demolition. It is obvious that a new approach is needed for a shift of paradigm instead of weak attempts that focus on specific subjects of current situation. For this aim, the notion of open source, which emerged in computer technologies, adopted by different disciplines and started a democratization movement, is discussed in this research. The projection of this concept over the field of architecture in the last 30 years has been examined through different examples and the potential benefits of this advancements are reviewed in the context of creating positive outcomes for environmental interaction. Even though the open source architecture seems to advance through sharing platforms and digitalized production methods, we notice that examined references hold a deeper and more effective transition potential. It is logical to regard the hierarchical stages that are embraced for the life of built environments as the main reason for environmental problems and accordingly the examination results of this study reveal that open source architecture can create productive and integrative cycles to allow a better engagement, flexibility with local preferences and upcycle opportunities. Therefore, we believe that a more tangible idea for a built environment which can produce net positive results for humans and nature can be created.
