Can anyone recommend web sites that instruct one in the building of a
greenhouse? Googling doesn't turn up anything interesting.

Do you want to build it from wood, alluminium or upvc? start with what
you want to glaze it with as this nearly allways comes in standard sizes
and it makes sense to make the structure take these.

You will be hard pressed to beat a standard kit bought on line and
delivered complete with glass (which is the expensive bit)
