# Avoid obstructions, such as plants, statues, poles, etc. in front of the main entrance. These restrict the flow of positive energy.
# Two houses facing each other should not open their main gates towards each other in the outward direction. Such doors are believed to be very inauspicious and usher negative energy.
# All windows should ideally be of a symmetrical shape and proportionate in height. Irregularly shaped and inconsistently sized windows are a strict no-no, as they are deemed unlucky.
# A door should not be constructed in the center of a wall; it should always be off-centered. However, make sure it is not in an extreme corner.
# Ensure that the hinges of your doors are well oiled and open and close smoothly, without creaking. In addition, replace cracked doors as soon as possible to avoid quarrels.
# An entrance facing the east, west or north is considered auspicious. However, it is best to avoid constructing doors or windows facing the south or south-west corners to avoid the influence of negative energy.
Keep in mind that the main door of a residence must be bigger than any other door in the house (but not oversized). For luck and prosperity, the main door must be more beautiful as compared to the other doors.
# It is important to keep in mind cross-ventilation while fitting doors and windows. They should be placed such that maximum light and air can pass through the house. Therefore, it is suggested that doors and windows be placed opposite each other.
# A house must have an even number of windows and doors at all times, such as 2, 4, 6, 8 etc. but not 10 or multiples of 8 (count doors and windows separately).
