We're in the process of buying a house. Just found out that the vendors removed the chimney breast from the upstairs bedroom a year ago but left it intact downstairs and left chimney stack intact in the loft. It sort of tapers diagonally into the wall from about a foot below ceiling height in the bedroom. We just heard that they didn't get building regs approval to do this and the surveyor wasn't able to ascertain how the chimney stack is being supported as it's all been plastered over. What should I do now? The solicitor has suggested getting them to pay for indemnity insurance but this only covers us in the event of the council enforcing changes. It doesn't cover us if the ceiling falls down or we need to do remedial work. I want reassurance that the remaining chimney stack is being adequately supported and I don't want to encounter problems when we sell on the house in future. Has anyone been in this situation? What should I be asking for?
