Hey guys, right now on my property there's kind of an open shed, basically 4 wooden pillars that support a basic metal roof.  The pillars are attached to the ground with concrete.

My idea is to close up the structure using adobe bricks, above a rubble trench foundation that spans between the wooden pillars (or should it go around them?).

My question is, how do I go about attaching my adobe walls to the existing pillars and roof, so that they don't just fall over? (I'm new to construction).

Also, should I somehow treat the wood pillars, since they would be in contact with the mud mortar?

Thanks in advance!

I believe the right word is urbanite, not rubble. Basically left over from construction sites. English is not my main language

Hey guys, I'm currently building a cob chicken coop (circular shape, 4m in diameter) and had some questions.

I have already dug a 45cm deep and wide trench. I have decided I will use rubble for the foundation, since I don't have access to stones. My question is, can I just stack the rubble and compact it really well?

Otherwise I would use a lime and sand mortar, but I'm struggling to understand the point of it (I'm really new to construction).

Is there a YouTube video of a person actually doing a foundation like this? I'm struggling to find resources.

Also, do I need to dig out a separate drainage line too? How do I go about this?

If it helps, I live in a very hot climate where it doesn't rain much.
