Next door have just had a loft conversion and I went up there on the weekend & they have taken a brick out into my loft and are venting into mine. Is this allowed

Dear Maddstew, No it is not. Unless they had a party wall agreement in place they are not allowed to carry out any work on the party wall.If they had your agreement to work on the party wall then they should have kept you aware of any work happening. You can demand the brick be put back in place and a suitable alternative be sorted. You can contact your local council's building control department if you don't want to deal directly with your neighbour. Although talking with your neighbour would be a better approach. Sounds like a bit of a bodge by the builders at any rate, Regards, John Briner Briner & Sons (Building and Roofing contractors)

No, it's not allowed as they have now breeched the fire barrier that this wall acts as. Before starting work on the loft they should have issued you with details of a "party wall agreement" which is a legal requirement on their part before any work commences on a shared wall. It sounds to me like they have knocked out the brickwork to install the supporting RSJ at ridge level which takes the weight of the dormer roof. This beam should not be extended over your side of the wall as it will cause you problems in the future if you decide to convert your loft. You now need to contact a specialist party wall surveyor to take on your case, the costs of which should be passed on to the neighbours. The Surveyors will advise on this.

No its not allowed. The cheeks of the loft should have been coated with fire proof board to gain an hour delay. No holes should be made and definitely there should be no venting in to your loft. Next door should have had building regs involved and they would have noticed this on their final inspection. Contact your local authority to check.

No it is not allowed. When next door had there loft conversion done the builder should have fire stopped the party wall. No holes or anything combustible should bridge the two dwellings. I would let your neighbour know, and if nothing is done phone your local building control officer.

was the builders name frank butcher?
