The Builder, thanks for your answer
the neighbours have only been living here about 4 months, don't really know them that well, they keep themselves to themselves only mentioned there plans to us a few days ago, so i don't know if they have got the building inspector involved.
Do you think the removal of the chimney breasts indoors would have any effect on my walls, i guess it shouldn't because of the cavity walls, just wondered what your thoughts were.
thanks again 'The Builder'
