Vastu Shastra has great importance for entrance door in a home, as this is the place from where energies, either positive or negative, enter and exit a house. Having said this, it is obvious that if more negative energies are entering a home from main door then people in the house will not prosper.
On the other hand if more positive energy is entering a home then the residents will have a better living and harmonious environment. A house is an extremely close venture for any person. Hence it is advised that you plan them according to essential Vastu requirements. Vaastu advice for the entrance gate will first involve portioning the main entrance into nine equal facades. The main entrance must be decided after conducting a necessary Vastu pooja.
Most entrances would involve two or more gates. Hence a west gate can always be placed towards the right side walls. And if you plan a south gate then let it position towards the left side wall of your house and opening southwards. Entrance of a house explains everything because this is the gateway from which energies constantly goes in and out. The main door of your home should always be the biggest door and should open up to positive and pleasant surroundings only. Do remember to keep in mind that intersection roads are the worst location for an entrance gate as they represent clashes.
