NUMBER OF DOORS
Total number of doors should be in even numbers i.e. 2, 4, 6, 8, 12 etc. Doors in 10 (ten) numbers is not good as it ends with zero, but may not very seriously affect the inmates but anyhow it is advisable to avoid that number.

SINGLE MAIN DOOR
When there is only one single main entrance door then the East or North side location is the best. It should be the centre but should be in the favourable position. Single main door from the South is not good at all

TWO DOORS
When two doors have to be fixed the combination should be North(M)and East(S), East(M) and South(S), East(M) and West(S),East(M) and North(S), South(M) and East(S); but should not be South(M) to West(S), West(M) to North(S), West(M) to South(S).(M = Main, S = Subsidiary). The best proposition is to have the main door in the favourable positions but in the extreme end.

THREE DOORS
When three external doors are to be fixed the following should be observed: Locating Doors on three sides other than East or North is not a good proposal. Locating Doors on three sides other than South or West is good.

FOUR DOORS
External doors on all the four sides is good. But in any case apart from the necessity of the good position for the door, it should be seen that within the compound either a tree, a pole, pillar, a wall, any junction, a water channel or a corner, temple etc.(known as Dwaar Vedha) right in front of the door is avoided at any cost. The rule (Matsya Puraan 255.14, Agni, Page 104. B.S53,76 etc) regarding this says: "The distance of twice the height being left from the door to the Vedha there occurs no Vedha".

OTHER CODES REGARDING DOORS
Never place a door in the middle of the facade rather of the house. Doors in the upper storeys must conform to the doors below No two doors (Main entrance doors of the two different facing each other) should be exactly opposite to each other.

More than five Shaakhas (frames) are not allowed in the composition of the door to be placed in human dwelling. This indicates that apart from the usual four frames an additional fifth one can be used to accommodate a ventilator within the door.

Ancient texts like Vishwakarma Prakash and Brhit Samhita suggest that the door of residential building should have a height equal to three times the width though the common rule is that the height of the door should be twice the width. Placing of the doors in all the four directions has been recommended for variety of auspicious reasons.

ENTRANCE DOORS
It is advisable to fix the main door by selecting the favorable position instead of following the sign (Rashi) or constellation of the owner of the building, as the structure may remain even after the death of a particular person and other may continue to live in that place. The following are the good positions.

The effect of the position:
North-North East (good) = Ensures Financial gains
East-North East (good) = Causes Enlightenment.
South-South East = Ensures improvement
West - North West (good) = Ensures Success.
North-North West (bad) = Creates Un stability
East - South East (bad) = Causes adverse effect.
South-South-West(bad) = Causes Financial constraints and ill health of women.
West - South West (bad) = Causes Financial loss degradation of men.

The main door & other exit doors on any side of the building should be located at proper places.
