This little building was on the property when we bought it, in 2010. Now, we know it is for plants. Is it a greenhouse? Or something else? It only has the door and the windows for light and ventilation, no sky lights, it is oriented E/W....located almost behind the garage.
It has low plant shelves, on 3 sides, below the windows. To us, it just looks like it doesn't make a very good green house, or grow house or anything. Oh, it has a shingled roof and a concrete slab foundation also. Any thoughts?
