Vastu specifically gives out rules for the
shape of
building which has primary
significance in
Vastu. Shermukhi and Gaumukhi shapes are given importance in Vastu because these shapes decide over-all prosperity and
happiness of inmates residing in house. Gaumukhi is considered
excellent for
residential purpose while Shermukhi is favourable for
commercial property.
Although
Vastu gives more importance to
direction yet shape of building is significant for every type of building, in other words we can say that both shape &
direction are primary for the property. There is no other thought which is more important in Vastu shape or
direction because if direction is incorrect then even good shape of property can’t help and vice versa.

Gaumukhi generally is narrow from the
entrance if
North and
East are suitable
directions and goes broad from inside. Shermukhi is just juxtaposed to Gaumukhi having an extended
North or
East and narrow
South or
West which is considered inauspicious for residential purpose but suitable for commercial. Gaumukhi on the contrary have an extended
South and
West which is not auspicious for residential property.
We shall say that no property can be perfect in all terms and shapes but we need to consider the shape of property wisely before purchasing. To enjoy
benefits of such shapes it is ideal to construct
entrance as South or West while in regular shape properties only East or North
entrance is preferred.
