Vaastu is complete understanding of direction, geography, topography, environment and physics. It is a study that dictates the form size and orientation of a building, in relation to the plot, soil, surroundings and the personality of the owner / dweller. There is no room for rituals and superstitions.

Vaastu orientates, places and dictates the proportions of every detail as in building lines, skylines, elongations, levels, slopes, water tanks (underground and overhead), kitchen, bedrooms, toilets, staircase, heights of ceilings and roofs, entrances and loci of doors and windows, compound walls and so on.

Architectural science and equipment have undergone a sea change over the years. However, the principals of Vaastu, although modified to suit the modern times, still remain applicable.
