The VCL would normally be on the warm side of the rafters and insulation. If the insulation is above the rafters you should be able to fit some rockwool between them without issues. You could also fit resilient bar before you plasterboard.

The woolbatts could be dritherm 32 which are mineral wool and get installed by the bricklayer. They are soft so easier to get right than rigid insulation so fairly idiot resistant. Pumped beads are EPS beads that get injected after the shell is complete. Makes the bricklaying more idiot proof. Both the above are best with a 150mm plus cavity.

+1 with pressure treated close board panels it looks a decent spec.

MVHR but it can be tricky to install.

The only downside will be screwing through any pipes or wires or possibly disturbing an asbestos ceiling above.

Mass market range I think.

DIY Kitchens have Blum drawer boxes and hinges. https://www.diy-kitchens.com/about-diy-kitchens/our-partners/#blum

Bear in mind what @Gus Potter pointed out. You won't easily get these to bear on the party walls and there is likely a lintel over a window on the outside walls which will mess you up.

There you go. There is nothing you can do via the council. I very much doubt if that was how it was phrased. I am not sure why you have got so wound up about this, but I suggest you either take your neighbour to court or drop the matter.

I have had an engineer specify joists at 200 centres for part of a floor, so it is not unheard of. We ended up splitting the span with a flitch beam so we could do 400 ctrs.

I thought the outer bits were less prone to cupping. Is this from Vastern?

The point is it could make the property unsaleable. I agree that badly fitted pir boards are hopeless. The EPS beads and cavity batts are non contentious.

As per my previous advice, if the Local Authority don't think it is an issue you will need to take your neighbour to court. If the neighbour's house is oriented at 90 degrees to yours the fence looks like it is protecting the amenity of their rear garden. Either way, this does not look like it stops you safely entering and leaving your driveway. I would just drop it and move on.

I would not recommend any spray foam insulation. It could be a disaster for insurance, mortgage or resale purposes. I doubt these even have current BBA certificates.

I have used Cemfloor flowing screed and there does not seem to be such an issue with laitance as it is cement based.

They are having a panelised system so N/A. Paying part by credit card could give some added protection.

I like the guaranteed airtightness results you get with the likes of MBC and the whole superstructure being the responsibility of one entity. If something does not work out on site or BC pull you up, you know who needs to get it sorted.

I think that is a large risk. It would be far safer if you got a firm to design, manufacture, deliver and erect.

Red would be foul, blue surface. You would need to divert them if they are near the proposed building. Don't assume they are near where the drawings indicate. They may be fairly deep.

Not the best but it will be fine. Are the bricks Forum Smoked Branco? The mortar goes well with them.

Sorry but 25mm conduit for a 25m run is a no-no. Can you get a Cobra type duct rod?

Swap the dishwasher and the drawer unit.

Use resilient bar at 400ctrs instead of batten if there is habitable space above.

Bear in mind that the planners often want you to be able to go in and out in a forward gear, so you will need space on site for turning. You may do well to extend the driveway / parking areas.

Is the plan to make it all line up left to right and along the length?
