I really like the "patina" metal siding, and the slider door. It looks like a much more usable, and functional space than the previous big box store shed.
Here was my Covid project greenhouse...I built it exactly the same as the instructions, except for adding 4' in length. My wife currently has it filled with growing plants, and mood lighting.
