    Hi,

    I'm (probably foolishly) having a go at submitting plans to BC myself, so apologies for the probably stupid question.

    I'd like to move a partition wall between the bathroom and bedroom, and after phoning the council, I think I need a warrant.

    The current wall runs parallel to, but betweenthe floor joists, so it's only secured to the floor boards.

    I'd like to move it, but ideally I'd be moving it to between the next two joists.

    I phoned BC and spoke to someone with not much time for dafties like me, who said that this would be fine (I'd assumed it'd have to be above a joist), but I'd need to put "??-angs" between the joists every 600mm to support the partion.

    I'm geussing this would be joist-sized (150mm x 50mm) bits of wood perpendicular to the existing joists? Should I be specifying / using some kind of hanger/bracket, or can I just nail it in? Have I totally misunderstood?

    Thanks for any help.

    We assume its not load bearing, fit your infill joists to the existing with either hangers or screws, nailing will just shake the whole floor causing cracks/paint flaking etc in the plasterboard ceiling below.

    Perfect, thanks!

    Yeah, sorry, should have said, it's not load bearing. Floorboards underneath, Plasterboard on top with "noggins".

    Also, I was wondering about what BC would consider acceptable sound insulation? I was going to overlap two layers of 12.5mm wallboard on the bedroom side, one layer of moisture board on the bathroom side, but first stick some cheap and cheerful loft roll insulaton between.

    Is that good enough? Don't really want to have to spring for £100 of boards if a £8 roll will do.

    Yes a layer or 2 of rockwool will be OK. Use Aquaboard to any tiled areas in direct contact with water overspray ie behind shower etc.

    Purely from an interest point of view, why are BC involved if this is just a partition wall?

    I'm not sure to be honest. I phoned them, described what I was doing and they said that it sounded like I'd need a warrant.

    Sorry to revisit this two weeks later, but I'm finally getting round to this and wondering what timber I can get away with using for "infill joists".

    Ideally I'd like to get away with 38mm x 63 or 89mm CLS, but would I have to use something 50mm? get away with 50mm x 47mm?

    I would have just used the same size as the existing joists.
