i would love to have an indoor shed area like that for fixing equipment and absurd art projects. or like hosting the occasional stupid huge gathering.

with just a little bit of air handling and some commercial equipment, you could go insane with growing fuckloads of potatoes, storing them somewhere consistent temp/humidity, and even processing them into like your own custom french fries for sale to nearby restaurants and retail grocers.

otherwise, that place looks like groverhaus if he won the lotto and had professional contractors and an architect to try bring a manchild's incomprehensible scribblings to life.
