It is big and I love your shelving units. Are they professional units? I have not seen any like that. Nice touch with the lamp even if you don't work out there at night. And neat idea on the shade cloth. I would have never thought of putting it in the inside.
We have temporary water and electric right now but hopefully it will get finished this summer when the GH is empty. I like the brick floor too. Makes it very neat and tidy even with things in the works.
