Rubble foundation - PEM BB building.straw.rubble

This is a badge bit (BB) that is part of the PEM curriculum.  Completing this BB is part of getting the straw badge in Building.

While building a house may be out of reach at the moment, let's get some practice putting together smaller structures.  Using local construction materials you can harvest yourself is a great idea.  Cement doesn't grow on trees so let's try to make a foundation with gravel.  Not that it does grow on trees but it's a bit easier to find...

Here are some pictures of what we're after:  
 
 

And here's a nice introductory video:
