The construction of basement has become the need of time due to limited space available for residence. Though a vacant space under the house is not considered auspicious according to Vastu, yet some points are considered while constructing a basement. 

Vastu says to build basement in northern or eastern portion of the house. It is necessary to keep more vacant space in the North and East than in the south and west. Keeping this in view, the basement in north and east direction is beneficial. Ideally, basement should not be built under entire house.  
Basement should not be used for residential purpose. It can be used as store room and office. The interior of basement should follow principles of Vastu. Vastu says that more space should be vacant in northern and eastern portion of the basement. Place heavy equipments in southern and western side. An odd shaped basement causes loss in business, diseases and hinders the flow of energy to the owner. Rectangular and square shapes are auspicious for basement. 

Some people use basement as storage tank of water. Storage of water in basement would always be auspicious in north-east, north-west and at eastern and northern angles. If the position of water tank is changed from this direction, it may cause adverse effect on health. 

North-east of basement should be kept light, big and heavy things should not be placed there. Northwest of basement should be lighter than south-east.  Heavy material should be kept in south, south-west and west direction.
