I was impressed that a guy like me could put this thing together in 2 days, but if you could afford the professional assembly it might be worth it.  Also, the instructions were 1/2 inch thick and not a word of text.  I've got it tied down with ratchet straps and hope it survives the winter and wind we have here. The amount of engineering to send this thing in a box and have it turn into a  respectable little greenhouse is impressive.  TRUMP 2020
