Hi All! Didnt get answers so perhaps I was too chatty (long winded).
Would I need a sort of riser every 2-3 feet to stabilize the box? Box is in
8ft long sections, nailed to an inner frame.
I also got some advice from a co-worker. He said due to the size and that
I'm putting it right up to the footer, I should call the city code office
and make sure I dont need a permit. He added that in my area the bottom
will rot out faster than I thought and I should raise the wood up off with
some sort of cement blocks.
