A variance once granted shall not be withdrawn or changed unless so approved by the Board of Appeals. Further, if after the expiration of six months, no substantial construction is done in accordance with the terms and conditions for which such variance was granted, the Zoning Inspector shall give notice, in writing, to the person who secured the variance or his successor, and thirty days thereafter, the variance will be deemed null and void and all regulations governing said premises in question shall revert to those in effect before the variance was granted.
