Vaastu

Vaastu shastra is an ancient science which helps one to get the natural benefits freely offered by the five basic elements of the universe in which we all live. These basic elements are Akash (SKY), Prithvi (EARTH), Paani (WATER), Agni (FIRE), and Vayu (WIND). Vaastu Shastra can be applied by keeping in harmony with these basic five elements of nature. It is an edifice science that was developed by our learned people thousands of years ago. Its application today is purely architectural and its principles are based on becoming one with nature. Like astrology and palmistry it is a vast & complicated science, easily misunderstood by most people. Most people all over the world will not think twice before spending huge amounts of cash on designing their houses and they should rightly do so. Vaastu is essentially the art of correct settings one can place himself in such a manner as to derive maximum benefits.
Vaastu Shastra works on three principles of design that cover the entire premise.

The First is Bhogadyam, which says that the designed premise must be useful and lend itself to easy application:

The second is Sukha Darsham, in which the designed premise must be aesthetically pleasing. The proportions of the spaces and the material used, in the interiors and exteriors of the building - ornamentation, colour, sizes of the windows, doors and the rooms and the rhythms of projection and depressions - should be beautiful.

The third principle is Ramya, where the designed premise should evoke a feeling of well being in the user.
Vaastu Shastra is a complicated form of science put together by seventeen sages. There are certain rules that should be followed while  building. For instance, the building's underground water tank or well should be situated in the northeast direction. But, if the building has an overhead tank then it should be placed in the southwest direction. Also, more space should be left to the north and the east of the building compound and less on the south and the west. Open space should be kept around the building and if the plot has a road on the east-north directions, it is better for the inhabitants. Vastu aims at controlling the energies. It helps in enhancing positive energies at home and office for the better outlook, prosperity, wealth and success of an individual.
