OPEN SOURCE ECOLOGY

Programs

1. First Program Service Accomplishment - Education and Builder Training This year Open Source Ecology expanded its apprenticeship and builder training efforts through development of the Builder Crash Course and Future Builders Academy programs. Initial recruitment efforts in September faced operational and participation challenges, leading the organization to refine its outreach strategy and produce additional public-facing educational and marketing media. A second recruitment effort resulted in a significantly larger turnout for the December 2025 Builder Crash Course, which hosted approximately 50 participants in a hands-on construction and training program centered around production-ready open-source housing. Following the increased participation and infrastructure strain experienced during the December program, OSE continued substantial investments in educational and operational infrastructure to support future cohorts and scalable training operations. This included construction of the new Rapid Learning Facility and construction of a new 10,000 square foot Hangar with multiple bays dedicated to builder training, fabrication, collaborative work, and hands-on technical education.…

2. Second Program Service Accomplishment - Open Source Housing Development OSE continued development and demonstration of open-source housing systems through construction, deployment, and market validation of Seed Eco-Home models. During the year, OSE completed construction of its first market-ready production build, the Seed Eco-Home 4, which was placed on the market and entered into a signed sale contract near year-end 2025, though the sale had not yet closed as of the end of the reporting period. OSE also sold one completed Seed Eco-Home 6 residence to a local customer. The purchaser had previously participated in OSE's workshop and training programs, representing the first completed cycle in which a participant was trained through OSE educational programs and subsequently became a customer of the affordable housing model developed through those same programs. This provided an initial demonstration of real market demand and fulfillment within OSE's integrated framework of workforce training, open-source housing development, and affordable housing production. These activities support OSE's exempt educational and charitable mission by developing publicly documented, replicable, and…

3. Third Program Service Accomplishment - Open Collaborative Design and Documentation Systems In response to rapidly advancing artificial intelligence capabilities and the increasing feasibility of collaborative design automation, OSE initiated development of open collaborative design and documentation systems intended to make technical knowledge for housing, fabrication, and infrastructure more publicly accessible, reproducible, and scalable. OSE has historically published open-source documentation and technical knowledge as part of its exempt educational mission; however, recent advances in AI-assisted workflow generation, documentation systems, and collaborative design tools substantially lowered the cost and complexity of producing and organizing public technical documentation at scale. During the year, the organization began externalizing internal organizational know-how into publicly usable documentation systems, automated workflows, modular design methodologies, and structured collaborative development processes. This work included early efforts to formalize construction knowledge, design logic, workflow sequencing, and production methods into machine-readable and…
