You might even be able to incorporate your potting shed into it somehow. I’d have a green house, if I had the money. I’d put it right where I could step through the patio doors and right into the green house.LOL
That would be ideal, but a greenhouse needs power and it would be a bit too spendy to get it out to the garden.
I’m thinking maybe an addition to the west end of my workshop might work out pretty well.
