According to Vastu Shastra the materials that are used for building are of great importance. These are the commodities that compose the building or a flat. Hence it is vital that while using building materials the rules of the Vastu Shastra are precisely followed.
While building a new house all the material should be new. Even if the wood of the old house is in good condition yet the doors, windows and other wooden units must not be used as much as possible. The logic behind this is that the chances of repetition of disagreeable incidents in the new house remain. Also the unhappiness about using the old things will linger in the minds of the residents.
If it is difficult to replace everything that is old then at least the entrance door of the older building should not be used. Similarly old tiles, remains of the kitchen platform, bricks, stones etc. should not be put into use in the new building. Old wood should be sold and using the money so obtained, one should purchase new wood for doors and windows if possible. Iron grills should be used only it is a dire need otherwise it is preferable to apply wood.
If teak wood seems too dear then one can always opt for other types are woods that are cheaper yet durable. However, wood of Gum Arabic tree or any other thorny tree should not be used. They throw negative rays. The Gum Arabic tree is usually compared with a demon. This is the reason why the carpenter`s plane is made of this wood because by using the plane made of this wood they would be able to work hard and fast like demons.
Building material, which is in store for a long time, even though it is available cheap, should not be used for building a new structure.
