Only if the combinations of directions and energy is very good, then residents will live a happy, healthy, prosperous and peaceful life.
The photograph on the right is : Land (centre - Brahmasthan) Activation work under progress at ZEE MEDIA CORPORATION, FILM CITY, NOIDA. Land activation or energizing the piece of land on which a building is proposed to be built, be it residential or commercial, is an important aspect in the field of Vastu. The piece of land has to be free of 'Vastu Dosh'.

If so, then the effects would be very negative.
