Vastu tells us about the start point, the “Entrance” of the house… The main door serves as both a family entryway and a source of energy and vibrations. This makes it even more important to situate the main door to face the north, east or northeast, when we step outside the house as these directions are considered auspicious as they bring happiness and positive energy into the house.
Regardless of the above ideals, the second options of north-west and south-east can also be acceptable.
