My dad did this using some old steel framed windows from a school renovation. He purchased the windows atban auction for $25 and then welded them together to form the walls. He used thin steel framing from some old school lockers also purchased at the auction to hold it all together. For the roof he used corrugated tinted plastic. He used the steel framingbto build shelves inside for potted plants and such. He also put a cheap oil burning heater that used old motor oil for energy source to protect the plants in the event of a sever weather event that occasionally happens in early spring and fall.
