Ceiling Height in Dormer after Dry Lining

    Hi there,
    I am looking at dry lining the upstairs bedrooms in my dormer bungalow. The plan is to dry line the knee walls, slopes and ceiling with 62.5mm insulated boards.

    I just measured my ceiling height and it's currently 2.44m. If I proceed with my current plan, after skimming the boards, my ceiling height will be reduced to approx 2.38m.

    The question is, could this cause me problems with building regulations if I ever decide to sell, since the ceiling heights will be below 2.4m? House was built in 1994. Thanks.

    My opinion is no. 2.4m is a suggested height and we don't sit there with a tape measure to ensure its 2.4m on our site visits.

    BryanF, what obligations?

    Kceire, so to my understanding, this ceiling height of 2.4m is just a suggested height and not enforceable? 2.38m should be no problem?

    the way i would look at is ... if its a new build it should be constructed to comply

    as its an existing build from 1994 its substantially in compliance at 2.38

    im not even sure if the 2.4 m 'suggested' dimension existed in 1994

    I personally know a house where the sale fell through due to 2.38m ceilings.

    There's a good chance the purchaser just wanted a way out - but either way - this was the stated reason and it wasn't something that was easily changeable by the vendor.

    That's a 60mm difference in height. Could you not use a thinner board, meet the 2.4m suggested height and beef up the roof insulation in the flat ceiling section if necessary, or even just beef up the attic insulation anyway. I'd have concerns about future buyers raising it as an issue to be honest.

    Thanks guys, I think I'll play it safe and keep a min ceiling height of 2.4m, just in case.

    I'll probably go with Supertech's advice and go with a thinner board and/or beef up the insulation above - makes sense.
