Nevertheless, if one follows meticulously the principles of vaastu in selection of the plot and construction of building, satisfactory results could be obtained in majority of cases.

• The site should be a good square or a rectangle if possible with south-west corner equal to 90 degree.
  
• North, east or north-east roads would do more good with two gates, one in the east and the other in the north. Besides the north-east, south-west or north-west blocks are also good.
  
• Ground levels should be sloping towards North-east, and the levels in south-west, should be higher than all other sides.
  
• An open well or a borewell should essentially be dug in north-east, before the construction takes place.
  
• While designing the complex, more open space should be left in the east and north compared to west and south.
  
• Balconies towards north, east and north-east are advisable and better not to keep balconies in south and west in general.
  
• Kitchen is advisable in south-east, or north-west and never in north-east.
• Pent Houses should be planned in south-west on the terrace.
• Staircases have to be in south, west or south-west and to be avoided in north-east, because head room of the stair case, higher than south west is not acceptable.
• Main entrance into the flat could be from east, north, south, north-east, west and north-west.
• No wells or borewells should be dug in south-east, north-west or south-west.
• Cellar should be kept under the northern or eastern portion of the complex, and not in southern or western side.
• North-east cellar to be used for parking of vehicles; better if they are not heavy trucks.
• Open area in north-south should be used for lawns, borewells and sumps.
• Open area in north-east can also be used for on and off parking.
