[Should there be changes for the Southern hemisphere?]

Can anyone tell me whether there should be any changes made to the elements etc for people living in the southern hemisphere. My personal feeling is that there should be changes and they are as follows.
North - Fire - Midday - Summer
West - Metal - Afternoon - early autumn
South west - Soil - Late afternoon - Autumn
South - Water - Evening - Winter
East - Tree - Sunrise - Spring.

[Which door do I consider as my main entrance door?]

Our living area(facing west) faces a large open area of land on a golf course. But the entrance onto the property from the road faces east. Our kitchen door faces south. Which would we consider to be our main door. To enter the house we mainly use the inter leading door from the garage into the kitchen, this door faces north and the garages face east. Is this considered the main door or would the garage doors be the main entrance into the house as they form part of the unit.
