I plan to buy a 8 by 20 greenhouse this year, to keep the view from
the house, it would look better if the greenhouse was erected South to
North, how much dif fence will it make, rather than the conventional
East to West.

The most important thing to remember is not to erect it so that you are
dependant on light coming from the direction of neighbours. One of my
neighbours did that and new neighbours on his southern fence promptly
planted a Leylandii hedge and let it grow until he could only grow ferns in
his greenhouse.
