The shape of land or plot plays a very important role in success and failures. There are two typical shape which always talked about in Hindu culture is Cow and Tiger or Lion face shape plot.

Gau Mukhi faced plot is very auspicious for both residential but not for business while Wagh Mukhi is mostly in-Auspicious for both. Fengshui consider Wagh Mukhi as auspicious.

I have seen few Wagh Mukhi plots where none of the business has survived for long. Two place where I have seen as many as 3 different shop outlet in the span of 4 years. These outlets are multi national brand and they were not successful. But there are small shops with perfect 90 degree cut and shape of Wagh Mukhi plot are doing excellent. Wagh Mukhi for residential is 100% No-No.
