I believe in the saying a place for everything and everything in its place
but I have never achieved to put it in to practice.
As for the shed bigger it is 14 foot x 10 foot x 9 foot high
the extra height will give more shelf room for 25ltr drums.
A door on the rear wall will give the option of extending with
a lean-to for extra storage.
I have a 15 foot x 20 foot garage and a 14 foot x 23 foot workshop
both full to the gunwales with crap and knowing me if the bio shed
is to big the temptation to fill it with non bio stuff will be to great.
I like the idea of the dishwasher for cleaning drums I have an
old dishwasher and have tried to think of a way to make it
clean the inside of the drum.
And as for the penal warts that's to much information.
