Oh, right. I have a blog.
Between a bit of a tenuous return to work after my flu episode (where I filled in for 2 people who quit and 4 more that also came down with seasonal plague) and the fact that I’ve been busy with a side project for a while, it’s been quite a few days since a real post.
I have been making a few strides in the cabin design in that I’ve finalized the overall layout of the interior and most of the left side framing layout is now complete. Which brings me to licensing: I want to make this design accessible to as many people as possible without making myself liable beyond the scope of due diligence. I.E. I want to do a good job making sure I cover all my bases with regard to structural integrity, but I don’t want to be sued into oblivion for my trouble.
The Cabin design will be Open Source
All the structural aspects of the cabin will be open to anyone to download (I’ll probably make a full download link available here), and modify for their own needs without having to pay me royalties. All I’m asking is for the copyright to remain intact.
That being said, I’ve been using a heavily modified ISC license for the past two times I’ve released any updates. This, I feel, isn’t really applicable to structure since these were originally meant for software. Being a software developer, naturally that was the first place I looked. I’m still using a heavily modified ISC license, but I’m open to suggestions on how I can license it.
I need to find or create a good license that will help me share my ideas without being subject to any sort of litigation. We’re talking about structure here and there’s a real risk of injury or worse if it’s done incorrectly. But I still want to let anyone feel free to modify it without too much legal wrangling while still indemnifying me.
Is it safe?
This has really been the question that’s stayed with me since I started on this journey.
I’m not a trained engineer, although I think I’ve taken reasonable steps to ensure everything is structurally sound, however I’m using OVE (Optimal Value Engineering) practices where applicable. I.E. 24″ On-center stud spacing, 6″ studs and using standard length materials (using 96″ studs as much as possible) to reduce weight, maintain proper insulation and still remain structurally sound to snow and wind loads. Also, I’m avoiding any cuts to the studs for the windows. The only cuts to the studs are at the front door and the bathroom entrance of the internal wall. I’m considering eliminating the center column by turning the bathroom wall into a load bearing one. We’ll see.
OVE is still somewhat controversial among builders for varied reasons. Some people believe it’s not as secure, others think you’re not really saving on materials, so there’s no “value”. My opinion is that the “value” comes with energy-saving. Granted you’re using less material, but this is not the primary benefit.
A sneak peek
Here’s the last sketch I did of the left side external framing layout. Note: The angle of the roof is approximately 50 degrees to accommodate year-round solar panels for the Northeastern U.S. This isn’t optimal since, ideally, you should be able to change the angle, but I don’t expect people to hop on the roof every few months to do that so this angle will have to do.
I’m still going with a 16″ x 16″ footprint with a 16″ x 8″ loft. Shaded in areas on the 1st floor are the support beams. See the previous foundation update for how they’re put together.
Special thanks to Kelly and her partner for offering me advice along the way.
