Obviously I can't tell the size of yours in the picture, but that looks like what I bought: 10 X 10; metal tubular frame; heavy plastic cover, with a zippered front door, and a zippered rear vent window. 5'4" side height; 8' center height.
She also threw in the silvered sunshade for over it.
Since I don't have shelving for it, I plan on putting my pair of 2' wide and one 4' wide '4 tier greenhouses' inside it.
