A business premise is much different from a residential building. The door of a residence opens inside while the door of a shop opens outside or upwards. A roller shutter fixed at the entry of any room normally indicates that it is being used for commercial purposes. A shutter, which is larger in size than a common door, makes it lion faced (sher mukhi). On the contrary, a simple small door opening inside makes the premises cow faced (gau mukhi). A larger opening not only invites more clients and more shoppers, it also advertises your goods and services as well. A smaller door, on the contrary, is good for residential premises as it helps in maintaining privacy, safety, security and sanctity of the house and its inhabitants.

Residence is mainly meant for sleeping at night. The second most important activity in the household is cooking and it should be performed only during the daytime. For this purpose, south-east is considered the best direction. Likewise, the daytime activities - the business activities - are best done in the premises facing south-east. This area is called the "Wealth Zone" in Feng Shui, the Chinese equivalent of the Indian Vaastu Shastra.
