There are a few landed development where all houses are without its own gate. Also, the carporch is located at the back of house, where the owner will enter from kitchen and the living door actually open to a common garden/park shared by the community there. (Desapark City - Nadia, Adiva, Sejati Residences, Symphony Hills.....)

1) Is the back door is the main entrance now?
2) Is the living room door still the main door?

The kitchen door is my entrance. So it is considered as the "main" door too?
