Vastu Shastra is an ancient Indian system of architecture and design that is believed to bring harmony and balance to the spaces in which we live and work. It is based on the principles of the five elements (earth, water, fire, air, and space), as well as the cardinal directions and the position of the sun and stars. In this context, Residential Vastu is the application of these principles to the design and construction of homes.

The first step in incorporating Vastu principles into a home is to choose an appropriate location and layout. According to Vastu, the ideal location for a home is north or east-facing, as these directions are believed to be the most auspicious. But as per advanced vastu principles it has been proved that all the directions are good. The only precaution and advice is that one must consult an experienced vastu consultant who can guide the proper direction by giving a proper and profitable entry gate as per the need of the client.The shape of the land should also be taken into consideration, with rectangular plots being preferred over irregular shapes.

The next step is to design the layout of the home, taking into account the different rooms and spaces that will be included. According to Vastu, the main entrance of the home should be located in such a way in the most auspicious entry point out of 32 direction entries. The living room, kitchen, bedrooms and toilets should also be located in specific directions as per the vastu rules and the nature of client’s job profile. 

The placement of certain objects and features within the home is also important in Vastu. It is believed that keeping certain objects or symbols in specific areas of the home can bring positive energy and prosperity, such as placing different paintings and sculptures as per the energy requirements needed to boost the positive energies in the space.

It is also important to consider the materials and colors used in construction and decorating the home, as they can have a significant impact on the overall energy and atmosphere of the space. According to Vastu, natural materials such as metals, stone, wood, and clay are considered to be the most auspicious. Similarly, each and every direction has its own specific colour to energize and balance the space, which should be chosen carefully.

In conclusion, Residential Vastu is a holistic approach to designing and building homes that incorporates principles of balance, harmony, and positive energy. By taking into account the location, layout, placement of objects and features, and materials and colors used, it is possible to create a home that is not only beautiful and functional, but also promotes well-being and prosperity for the inhabitants. 

It is important to note that an experienced vastu guide can bring harmony to the residents in an already constructed house or flat without demolishing the structure. Vastu Shastra principles can not be applied to one single point by hearing from some close friend etc. but it is advisable to consult with a Vastu expert when incorporating its principles into your home.
