Just put an offer on a 1950s semi in Stillorgan. House has been almost untouched since, so needs rennovation. Builder looked at it. Said looking at about E90k to do what I want to it, including 10k for rewiring, and E20k for replacing gun barrell piping and new boiller. Is the plumbing - replacing the piping expensive, given that a new boilder would probably be only 4k. Trying to get costs down to see whether it is worth all the effort of rennovation and the cost of it.
