Michael Judd says that if permies.com brings in $5000 to his kickstarter, then permies.com can decorate an entire page in his new book!
I'm not sure what we would put there just yet, but the opportunities for comedy are endless!

Hello all,

I'm going to build an earth integrated structure as in Mike Oehler's  'The $50 and up underground house book'
will be using John Hait's insulative umbrella concept as well.

I'm having trouble with confidence in wood species to use however.

I have access to about 20 Larch poles ranging in diameter of ~ 6" to 11". Lengths at 10ft. to 20ft.
I also have on site Beech trees, Oaks & Maples.

Mike mentions Larch as a good example however, I don't have enough Larch to do all the posts, beams & girders.
Could Beech, Oak, and/or Maple be used successfully underground if treated somehow?

I'm guessing that the insulative umbrella would significantly reduce wood rot right? In that case, does wood species matter so much?

Hug your destiny! And hug this tiny ad:
