Thanks both for your replies.
I have determined that some of the work was caused by my contractor:
1) a small hole due to the damproofing drill going through the party wall (albeit done by a very well known company!!),
2) making a 1-brick wide hole into a room when inserting a beam.
3)...
I had a question which you might be able to help with. First time poster, and first time property buyer, where I may have made a mistake!
I had some work done to my terraced house, where the Party Wall Act was required, but I did not get a Award drawn up. I was aware of planning permission...
