Before starting any work, generally the process of cleaning occupies the priority. Similarly, before starting construction, the construction site should be thoroughly cleaned and prepared for construction. This is called purging of the site from evil effects.
This process requires a well experienced Mason, who is as important as an Engineer. An inexperienced Mason with his inefficiency may mar the fortunes of the Residents of the proposed house. Many Masons have correct understanding of Vaastu, brought about by generations of experience.
The Masons, should possess accurate tools to mark the directions and to measure the site. Their important tools, set square to fix correct corners, intermediate directions, and plumb line to ensure perpendicular accuracy of the walls, should be used with diligence. The same tools should be used until the construction is completed, otherwise, there may be differences in areas of the rooms and place in between parallel walls.
First, the Mason should identify all the eight directions correctly, which is followed by cleaning and preparation of plot. The directions, South, West and SouthWest must be elevated than East, North and NorthEast. Any pits, shallow places, wells in weak or unfavourable positions should be filled up. The surface of the site should be leveled with raise in the directions of South, West and SouthWest. Avoid sites with anthills. Leveling and reforming, raising in the site must be done before starting construction, but not after, to avoid evil effects of Vaastu.
A well or borewell must be dug in North East, East or North after the foundation is laid and its water must be used for construction only. At least, a sump must be laid in any of these directions. The construction materials such as; bricks, tiles, wood, steel, stones, lime in North, East or NorthEast should not be stored in the aforesaid places; instead we can use South, West or SouthWest for storing them.
Starting of Work:
Work should ensure that the excavation starts from North East and proceeds towards North West. Repeat the same process from NorthEast to SouthEast and from NorthWest to SouthWest. This process should end by excavating the Southern side from SouthEast to SouthWest. The foundation work must start from SouthWest to SouthEast, SouthWest to NorthWest; SouthEast to NorthEast and end from NorthWest to NorthEast. Similar process is required for wall constructions. Importantly, at the end of any day, the walls on Southern and Western sides should be higher than the walls of North and Eastern sides. The temperature in the locality determines the height of walls; prefer high ceiling if the temperature is high and low ceiling if temperature is low.
Pillars should be square or cylindrical in shape but pillars in SouthEast must be invariable square in shape. Main entrance should not face the edge of any wall, pillar or compound wall. Likewise, there should not be any tree, well, sump or pit in front of the main door.
The NorthEast corner of the outer walls, compound wall should never be rounded off, whereas it is permitted in other corners. It is better not to have arches of semi-circular shape on gates located on Eastern and Northern sides, but such semi-circular arches are permitted on gates located in South and West.
The flooring of the house should be laid so as to facilitate the flow of water from SouthWest to NorthEast. The level of doors should gradually go on reducing from South to North and West to East. The floor level of the rooms in SouthWest should always be higher as compared to other rooms in the house and it should be lowest at NorthEast. The flooring should be strong and firm avoiding any shallow sound.
If one is demolishing any old house, they can start it from NorthEast and store reusable items in Southern or Western parts of the site, since the work if starting from South or West brings ill health to senior male and female members of the house.
