Builder Crash Course - December 2025
Update
Friends,
After the flurry of interest spawned by our recent viral video, the dust is settling. We have updated the website -
https://www.opensourceecology.org/builder_crash_course_2025-2/
Please review the update. The dates should now be correct, and registration form is updated. Early Bird cutoff is October 20, 2025.
Please read the logistics section thoroughly - https://wiki.opensourceecology.org/wiki/Future_Builders_Crash_Course_Logistics
See the section on pre-event preparation, work exchange, and how you can get the most out of the onsite time.
Note that we are waiving the HabLab hostel accommodations fee for work exchange participants - but retaining the food costs for the duration of the workshop. This should clarify any confusion from the older announcement - and please let me know if you have any questions. Then reigister and begin preparing by downloading our CAD file so you get the most out of the workshop. The more people download the file, the more transparent the build will be.
So now is the time to fill out our Workshop Logistics Form to coordinate, so please do that after you register and pay - for each person as that's where we send all info and communications:

Remote Sessions
Thank you for your interest. The way it works is we go over the design and build in the theory sessions - as well as the bigger picture narrative for transforming construction. The latter includes the big picture of solving housing, innovative build techniques, rapid build methods, integrated design, legal issues, and the bigger picture of solving housing with open source design and engineering. We focus on the technology and the social innovation needed to implement hardware technology into the real world. And much more.
The online sessions involve a video link during the actual presentation, which will be typically held in the evenings at 6 PM. We will go over the design and build for each day's work as well in the mornings. You can connect to those as well. The theory sessions will include a 45 minute presetnation, followed by audience Q&A. All sessions will be recorded so that if you miss a session, you can watch it later on YouTube. The presentations will also be released for public viewing afterwar the sessions are over. The perk of the registration is that you get to participate more closely by asking questions and interacting with the audience. We will start with 'interrrupt and ask questions any time', but if that doesn't work we will switch to 'save all qeustions for the end'. In any case, we recommend that people come ot the sessions with a noteboook ot take notes and maximize learning. If you register, you will also gain access to several preparatory sessions. In these sessions, we will go over the CAD model, discuss the overview of the build sequence, show you how to view every single detail of the design in the free CAD software called FreeCAD, and will also show you how to generate technical drawings (build plans) from the CAD so that you can use the master file to generate build plans for the whole house. This empowers you to review any of the exhaustive details of the build - which are all found in the complete CAD file down to every single building material item used. The master file includes information on the actual materials used. If you cannot make if to the build, you wi
