The focus of Vastu-inspired home designs is on creating harmonious energy flow around the house. The main design of the home affects that flow, where open spaces work as Vastu-friendly. Natural light is one of the elements of Vastu-friendly home designs, adding life to the home. The main principles include placing the main entrance to the north or east to be Vastu-inspired. Designing the rooms in a square or rectangular shape is a common practice among Vastu believers. Using natural elements like wood or stone at the time of house building is also a factor.
