Entering a new house is indeed the hour of celebration. Vastu Shastra talks about the auspicious time of entering into a new house in order to lead a happy life.

Whenever a new building is built, first of all, the house warming ceremony should be done and only after that the people should start living there.

When the sun is moving northwards from the tropic of Capricorn, it is the best time for entry into a new house. Normally, this period is from 22nd Dec. to 20th June called as Uttarayan. These are the days of God whereas the southward movement of the sun is known as Dakshinayan, which is Gods night. In the Uttaryan when the sun moves from east to west, it goes from the north direction. The movement of the earth is also like this. The sun is steady at one place. In the northward movement of the sun the auspicious sunrays are available in a large measure in the east and the north direction. In the Edifice Science, the east and the north sides having a lot of importance, the northward movement of the sun is more beneficial than the southward movement.

When the sun is in the Uttara, Magha, Pushya, Ashwini, Revati and Swati constellations in the months of Vaishakh, Shravan or Margashirsh at an auspicious moment, the propitiation ceremony should be preformed and then on the auspicious day the Grihapravesh entry in to new house should take place.

Ganesh poojan, Navagraha shanti i.e. Propitiation of the nine planets and the worship of Vastupratima i.e. Image of the building deity should be performed.

The image of Vastupurush, silver cobra, copper wire, pearls and corals etc. should be taken in a small earthen pot and some moss should be put on it. The faces of the Vastudevta and the Cobra should be in the east. This pot should be buried in the main southeast corner of the building. It is necessary that the mouth of the pot be covered with a lid. There is no harm in cementing the pit and putting tiles on it. No construction should be done on it after propitiation ceremony. This corner should always be kept clean. At the time of Vastushanti Balibhog i.e. Food, Rice, curd, flour lamps etc. should be given. This Balibhog or offering should be kept at a place where four roads meet. Then without looking back someone should enter the building after properly washing the hands and feet.

When the building becomes old and some repair works done propitiation ceremony should be done again. This increases the life of the building.

While demolishing an old structure, the demolition should start only after Kshma Yachna i.e. to beg pardon for the demolition.

The human being should take at least one round of the building after Vastupoojan. Ladies should take one round of the plot with water pots on their heads or shoulders. They should drop sweet smelling flowers while taking this round.

While entering a new house, first of all the people should bow heads to shri Ganesh and the Vastudevta i.e. deity of the building. After that the threshold should be worshipped. The chief of the house along with his wife should enter the house and go to the room on the northeast side. First of all, a pitcher of water or a vessel filled with water should be kept in the north-east corner, wheat and other grains should then be kept in the north-west corner, salt in the south-east corner and in the south-west corner a knife, dagger or a stone should be kept. After doing this all other articles should be brought in the house one after the other.

In houses without propitiation ceremony one should not sleep alone in the southeast or the southwest corner. If someone enters the new house without propitiation ceremony they have to face many dangers and calamities. While going to live in a house, which was closed or unused for a long time, propitiation ceremony should definitely be performed.

If some owner or builder has built row houses, flats, colony or a commercial complex in that case the person should perform propitiation ceremony in one of the flats, shops or houses and then sell it or give on rental basis.

The Vastupurush should not be buried in the open space around the building but in the southeast corner of the main building. The first Vastupurush should not be dug out.
