A responsible Vastu consultation cannot be based only on a direction name or a generic rule. The property must be studied as a living or working space. Its entrance, orientation, room placement, internal movement, construction stage, surrounding conditions and usage pattern must be understood together.
This is especially important for USA properties because many homes include basements, attached garages, open kitchens, townhouses, condos, split-level planning, large windows, home offices and strict remodeling limitations. A scientific and logical Vastu approach respects these realities before forming a conclusion.
The purpose of logical Vastu is not to frighten the client. It is to understand the property accurately and explain what is meaningful, practical and relevant.
