By erecting a mettalic pole, of atleast 1" dia with pointed top - (like an inverted cone); which is at a higher elevation than building ( 3-4 meters high) and then connecting the base of the pole to the earthing wire using a thick wire ( 5 - 10 mm). If that is not available dig a bore (4" dia ) atleast 20 feet deep into nerby soil, place the wire up to its base then fill the bore with a mix of salt and charcoal. Lo ur house is protected against lightning.
