First and foremost, I think what you're doing is awesome. I love it.

But I do have to wonder what your insurance company would say.
Couple years ago, the Safeco underwriter drove by my house and noticed my decks were 25-32" above ground level and I didn't have a proper railing around them.
Safeco gave me 180 days to bring it to code or they were going to refuse to renew.

I think the Safeco guy would literally **** if he saw your deck! ;-)
