I started off with the donated frame of a Greenhouse and some glass.

Next door demolished their shed so I used the wood for a floor and the sides which don't catch the sun

then the glass, and some clear plastic was scrounged up...Youtube tutorials taught me how to use a glass cutter.

First crop of tomatoes and peppers, only a few but a immense sense of pride and they do taste better than shop brought

its still a work in progress...some final finishing to be done some guttering needs connecting to the waterbutt. But total cost has been £20 for 2 packs of wooden battons, plus a further £10 for some waterproof paint before the winter comes in.
