There is a close relationship between Vastu and Astrology. In astrology, the fourth house has been attributed to immovable property, amongst other things. If the lord of the fourth house, the planets in the fourth house, the aspects to the fourth house, etc. are all good, then the person will enjoy property. Otherwise, the results will be negative. There are also many special conditions or ‘yogas’ such as Ayatna Griha Prapti Yoga, Vichitra Prakara Soudha Yoga, etc. which destine a person to different conditions of property holding. Further, one has also to see the planetary configurations at a given point of time, in conjunction with one’s nakshatra in order to fix a muhurta or an auspicious time for starting various stages of construction work as well as the griha pravesh.
