The principles of Vastu Shastra can be applied while constructing any part of the building or home. As per Vastu, there should be no vacant space under the house. If you have a basement under your home, then renovate it with by following the rules of vastu. Basements are typically used for storing things like furnace, water heater, or air-conditioning system and therefore left vacant and are not cleaned and maintained.
Basements should ideally not be built under the entire house. If that is impossible, use only the northeast section. Heavy equipment can be kept on the south and west sides. It is best that the basement should only be on the northeast or east side of a house. It should not, however, be located only on the south, southeast, or west side.
The floor of the basement should slope downward towards the northeast and the walls should be at least 3m (9 ft) high. The basement should be painted white and blue color should be avoided at all costs. The heater, water heater, or electrical panels should be in the southeast corner of the basement.
Since sunrays do not enter basements, this highly reduces the basement’s positive effect on the persons living in them. Therefore, a basement should not be used for living as far as possible. Basements are also not good places to conduct business. The basement’s effects will be improved if one-fourth of the basement is above ground.
