Interesting thread. Gail - did you have all the correct certification for the extension when you bought the house? I know English law is often different from up here but any extension requires signing off by Building Control and it's often the cause of delays in house sales here because that type of thing hasn't been done. Your solicitor should have requested and obtained all the necessary paperwork for you when you were buying. I think my first port of call would be the lawyer to get some clarification. Surveyors are also inclined to be very cautious so his report needs careful checking too as I find it odd if he was so ready to pass the building as sound. From your description of the neighbour's reaction - I wonder if he knows he shouldn't have put beds and borders against the wall and is worried about what may now happen.
I'd agree with the others about the damp proofing - these companies are interested in selling you their product. Nothing else.
