The entrance and main door are not only the place to welcome guests and an opportunity to make a good first impression on them but it also holds a lot of significance in Vastu shastra. As per Vastu it is also that area of a dwelling that allows the free flow of positive energy into the whole premise. Hence Vastu for the main door must be strictly followed in homes and offices (including shops, workshops, factories, etc.). Vastu tips primarily focus on the placement and direction of the main door. A main entrance door designed as per Vastu will help build and maintain cordial relations in a house between family members and relatives, and bring in more business in an office.
