The basic guidelines of Sri Aandal Vastu for residential buildings are:

• Choice of a plot is more important than the construction of the building.
• It is wise to choose a plot having North East road and avoid a plot having South West road.
• The Plot and the building should be square or rectangle in shape. There should not be any cut or extension.
• Construction of building should be towards the South West corner of the plot as it would leave more space on the North and the East.
• The North East portion should be comparatively lower than the ground level and the South West portion should be higher.
• The Main gate and the Main entrance should be on the positive direction.
• Windows on the North and on the East walls are mandatory.
• The Ceiling level should be even.
• The Septic tank and the toilet must be on the North West corner.
• Well, bore -well and sump should be on the North East portion.
• Overhead tank and heavy weighted material should be on the South West portion.
• Pooja room should  be located on the South East or North West portion.
• Kitchen should be on the South East portion and alternatively, on the North West portion.
• It is mandatory to construct the bedroom on the South West portion.
