Forest home foundation

I have a nice clearing in a forest to build a small cabin / cob hut.
How does one go about planning the foundation?

Trying to build with only materials from the property i.e. fallen timbre, cob etc..

As an option,
I Would like to put in a rocket mass in-floor radiant heating system or

Either way, there is no access by truck, so carrying in loads of gravel, rocks etc. will be a big effort,
would like to start the project now and finish by November=ish..
mostly doing it single handedly

Can you include your location in your profile? This will be important in determining your foundation. There is no frost line where I live but up north there is -- different requirements.

Since you are light on labor and wanting to get done quickly - hand digging the foundation and hauling materials by wheel barrow is out. A small farm tractor with front end loader and backhoe works well to do the earthwork (Kubota L series, John Deer 5 series, etc.). This kind of tractor is about 6 feet wide and maneuverable so you probably would not have to cut trees down. Put down scrap lumber or planks along the path to prevent soil compaction. You could probably rent a machine that would work.

To plan the foundation you need to know what the frost depth is in your area. A call to the building permit authority in your area should answer that one. Then you need to know what soils are present at the site for that depth plus a couple feet. What kind of material is found will constrain the foundation choices somewhat. Most soil conditions can be worked with. If you are trying to minimize how much material is brought in - a pier foundation would probably be best, but that would make the in floor radiant more difficult (at least a mass floor style). If you accept more earthwork and ferrying materials your option expand (rubble trench, footer/stem wall).
