There is a fews things to help you with fact
we all die.
you can not have too much power.
you can not have too big a shed.
Grass is horses and golf cources.
So concrete the whole yard put up some posts in each corner and fill in the gaps with roller doors ,windows and walls.
oh i nearly forgot a big fridge and a dunny.( no Grass to Pi55 on)
I think i may have to get rid of the dog as he don't like to S#!t on concrete.
And one other eco tip is you don't have to mow the grass which will give you carbon credits for the gas burning monsters in the shed.
