Advice plasterboarding single brick walls

Not sure why building control are involved.

 

As above, trouble is now they are you are stuck with them.

To save removing the battens already up, see if BC will let you put a vapor barrier over the top of them and then counter batten it to fit your sound boards etc.

 

BC required probably due to change to habitable room

bite the bullet, rip it all off - paint on DPC for the walls, membrane on the floor, warm roof (a proper one)

 

you'll have to be careful with the roof, do it wrong and you'll just get saturated insulation if you have it on the warm side before the vapour barrier - google warm roof, there's lots of detail dwgs around showing where the insulation should be in relation to the vapour barrier

same with paintable DPCs, or tanking compound

has the ceiling also been batterned by your ''carpenter'' ?

 

Why is it a habitable room, who would want to live in a drum studio? If you insulated the walls to keep your car warm would you have to inform BC?

 

like it or not, thems the rules - one week it's a drum room, next it's a bedroom, then it's being knocked through as a open plan lounge/dinner

 

don't just rip the Pb off and insulate between the joists, it'll saturate and cause discolouration due to condensation - ideally you need to raise the hight of the roof by 150mm approx to allow for the insulation, the BCO will tell if there are any planning issues about doing that

here's a piccy showing what to do, and what not to do to your roof

 

plasterboard - you don't have to raise the roof, the hight (externally) is raised - the insulation is in place on top of the existing

 

another point to remember (before you set your heart on the easy cold roof option) is that cold flat roofs are now not compliant to Scottish building regs, I'm sure you lot will eventually catch up - banned simply due to their poor performance and condensation/breath-ability issues previously mention

 

Or you could tell BC you had decided not to go ahead with the scheme and then do what you want, you may or may not have to rip the sound proofing out when you try to sell the house but...

 

Sean, way ahead of you in Stevenage, flat roofs are banned period, no flat roofs on houses at all, been like that for years..

 

it's a shame they didn't apply that retrospectively, good on em thou

 

well, there'll be 10 differing opinions of how to do this task on here - your best bet would be to ask your friendly BCO how he'd do it (at least then there's a fair chance that he might actually sign it off)
