You need to bear in mind that pir insulation is rubbish at keeping out noise, with a metal roof that is a major consideration

Put a concrete strip over it. the pipe needs to have a good covering of the correct gravel the concrete needs to be wider than the trench and place it’s load on virgin ground both sides of the pipe. look up a drawing for this. get it done and send evidence in.

From inside to outside mine is. plasterboard service batten pir board, taped and sealed to make vcl joists knauf omni fit between joists breather membrane spacer batten solid timber boarding special metal roof membrane standing seam.

His design is pretty crap he's obviously not considered building it or paying for it. couple of points, your roof is nearly identical to mine. are you sure you can use osb under the metal roof, the screws are really small and the pull out strength in osb is poor, I thought they said it needed to be plywood or solid timber. we went with knauf omni fit between the rafters and 70mm pir board underneath. ditch the insulated plasterboard and use a service batten then fit normal plasterboard.

what grade is it. My mate has just had a huge farm shed stripped by a professional company, and they just tipped it in a roll off skip. seams standard practice for a certain grade.

I would say if it a footing to take a pier to take that steel which is holding the entire back of the house up, then the foundation should have a proper design by a structural designer, then the foundation same as the pier. this is not an area to be guessing or scrimping. @Gus Potter

Have you bought a digger yet.

What’s holding up the top plates over that large opening, there’s not much of a lintel on show unless they have something on the outside.

CT1 rough the surfaces up with some sand paper. or stick a flash and patch over the holes bit bodgy but it will get you out of trouble.

I think that’s what I mean, told you I was thick. all fitted by the sparky. along with the other dozen in the house.

We have a heat and co2 in the kitchen as per regs, I just thought it might be something else a monitor would pick up.

Fark me there expensive. how much to a mate 😉

We have a gas hob, so was thinking of that with the monoxide, or isn’t that something to think about.

Morning, looking for something to monitor the air quality in the house for when we move in. looking to see if the mvhr is doing its thing and maybe a carbon monoxide detector built or anything you can think of that needs monitoring as well. simple device needed as I’m a bit thick. cheers.

The polystyrene isn’t needed. your over worrying.
