Open-source architecture
Not open sourced software architecture. For open source computer aided design tools see: LibreCAD, FreeCAD.
Open Source Architecture, sometimes referred to as OSArc, is architecture where the structure’s design documentation uses some form of open-source licensing, that often uses a modular design system, and seeks community collaboration and use. The concept began to appear in the early 2000s and was first applied to a built project’s design in 2005. Many open source architectural projects are aligned with public interest design principles. They are often motivated, in part, to address high costs and shortages of housing and structures for social development, such as schools and health facilities. Open source architecture draws upon a number of preceding and adjacent concepts including: vernacular architecture, citizen centered design, peer production, do it yourself practices, modular building, open source licensing, open source software, open source hardware, and the open-design movement.
