  • If the neighbourhood lacks proper height regulation and set back or if the housing pattern is not set, then it can even result in poor ventilation and lighting.

vastu-considerd-for-duplex-house-plansVastu is a science of dwelling home for humans. It defines the natural way by which different energies such as solar and celestial are balanced to bring more peace and prosperity in the home.

A home constructed on the principles of Vastu gives resident more enjoyment and heavenly bliss in life. Balancing the energies in the House can help you create a better atmosphere and brings more positivity.

One can understand the importance of getting Vastu based Duplex house plans in Bangalore; It again depends on How or How much one needs to consider Vastu while Designing their floor plans. Below are some of the steps.

Duplex Houses are those constructions that have double story designs. Designing duplex homes under the guiding principles of Vastu require spending the time to search regarding foundation, appearance and location of every part of your duplex home. A duplex house complete in all respects.


Below are some of the directions and shapes that can affect your home design

  • A shape of the plot on which construction is performed: Preferred structure types are generally rectangular or square.
  • Water Bodies: Bathroom and water tanks must be placed in the north or east end.
  • Obstructions: Pillars, trees, open well and posts must be avoided while constructing a home.

Apart from this, Vastu also doesn’t recommend to design homes or plots in L shape.

Several misconceptions are there when it comes to Vastu and everyone seems to have a certain opinion about it. To make it easier and simpler, let’s take a look at the different parts of construction under Vastu.


Before starting construction of your home, it is important to conduct bhoomi pujja in order to seek blessings from Gods and also to ensure that the land is free from any bad omens.

Vastu experts consider performing certain good rituals on the land to be an auspicious beginning to your home. It can be an excellent start to your proceedings.


To bring more optimistic energy and light to your home, it is recommended to position your home to your entrance. Another positive estimation is that sun rises from the east and it is always an auspicious direction. Another suitable direction is North East.

So when you are deciding to plan the entrance to your home, then you must decide where you want to have a home entrance since it plays an important role. Same applies to door positioning as well.


South west direction is not a recommended direction by most of the Vastu experts since it is often related to negative energies. Doors are not recommended to be facing to the south east direction.

South facing doors are also considered to be providing more usher to the sharp energies and therefore may cause disagreements or arguments under Vastu science.


If you are going to plan on building the kitchen in the house plan then south east corner is most ideal location. However, it is a common belief that cooking must be performed while facing the east. Vastu experts also recommend to not to construct kitchen directly in front of the main door of the villa or bungalow.


One of the best locations for building master bedrooms is south-west corner of an east facing home. Apart from building a master bedroom, it is recommended to have a rectangular or square shape of bedrooms, quite similar to the construction of your plot.

One of the prime objectives is to have a home build with the main entrance, bedroom and kitchen placed in the perfectly placed location so that one can sleep peacefully without any noise.


Vastu has proper information about positioning of bathroom or lavatory. From a general health perspective, a lot of emphases has been kept in the location of your lavatory in the home. Apart from all directions available, north-west location is the most suitable location for the toilet.

The other possibility is to construct a lavatory or toilet in the south east direction. Extra precaution must be taken to not place home temple room and kitchen exactly in the adjacent location to one another to keep your home free from any negative energy and keeping it healthy.

There should be proper well-designed core to the duplex homes, and there should be a staircase to make the circulation easy.

According to Vastu, it is best to have a staircase in the south-west corner of your duplex home because this direction act as a keeping the sun rays away from interiors and act as buffer zones.


It must be placed in the north eastern direction at the terrace of a duplex home. Plastic material must not be used as a water storage tank, and in case it is plastic, you must keep it as a dark colour such as blue and black to allow absorption of sunrays and kills bacteria.


It is important to leave more space towards North and east side of your home compared to the west and sound side. Leaving a space all around the house is always a good option considered as a good Vastu, and this also helps in getting proper ventilation and air circulation.

Vastu also helps in advising the orientation and size of a particular structure concerning the surroundings, length, breadth, soil and plot. It tells you direct proportions and minute details about the buildings and how it must be manufactured.


If you are planning to build your beautiful home, it is better to follow the principles of Vastu. However, proper care must be maintained if you are planning your home according to Vastu because designing in the wrong way or not following the complete Vastu design may make your home unsuitable to live.

Many people consider that Vastu is a superstition, but it has technology associated with it that makes it a proper science of dwelling your home in the best possible manner.

Some illiterate people just vaguely follow any Vastu without consulting an expert. Instead, one must follow suggestions and expertise from a person who has proper knowledge about Vastu.
