The Sun;

It is very important that you take into consideration the way the sun moves over your garden.  This is so that your greenhouse catches as much sun as possible.  In general, the best way is to position the length of the greenhouse running east to west.  Therefore the length of the greenhouse is most exposed to the sun and is south facing.
