Well, there's a possibility your main entrance and liveing areas face in any number of permutations.
Surely this depends on your floor plan - many houses with front door faceing south will have north facing liveing areas at the rear.
Our house faces north and has one liveing area at the front, ie facing north same as front entrance and the main windows of the 2nd liveing area facing east - but it is an east protected by full length alfresco so all windows of family room and minor bedrooms which face east are protected from full strength of morning sun.
These actually faced west in original plan but we flipped plan as we did not want large sliding glass doors and alfresco faceing west.
