In the fast developing world these days the population is also increasing rapidly, so that the small towns and cities are changing into metropolitan cities There is scarcity of land in the cities and the business is growing and expanding very fast. Therefore, huge multistoried buildings for commercial organization are being constructed and the number of such complexes is increasing fast day by day. Production has increased very much, and the factories have to open their offices and show rooms at various places for marketing their products. Therefore buildings for these commercial purposes have become a necessity. Most of the factories appoint agents for the sale of their products. The business men have to establish an office of the agency, which is located mostly in some multistoried commercial complex.

In the construction of multistoried commercial complexes all the principles of Vaastu-Shastra can not be followed so easily as in case of residential houses. The builder of such complexes wants to utilize each and every corner of the space available for construction leaving any space open, without any construction there may not be profitable to the builder. Commercial complexes which are constructed in accordance with the rules of Vaastu-Shastra become popular and prove to be beneficial and profitable to the business that is carried on from that campus. Therefore commercial complexes should also be constructed according to the principles of Vaastu-Shastra.
