hi there. In the past year i got planning permission to knock down an existing extension and build another one plus renovate my house on the same site. everything was going okay until such time as EIR ducts were found coming right to the surface beside my new extension so now they are at the surface and a foot above the damp proof coursing which could cause problems . I am living in this house all my life and i never remember these pipes going in. i have been told that they are in since 1972 which would make me 4 years of age when they went in. i obviously cannot remember this. These pipes are going through private property and they go right thru the driveway and out the back to there EIR compound. can anybody tell me what i can do to get rid of these pipes or to lower these into the ground . these pipes are going to be obstructed by my extension and nobody in the planning department had copped onto these before i got planning permission. I have put considerable amount of money in doing up my parents house and fear the outside of my house is going to be destroyed by these pipes . is there anything i can do about these
