Pack the reveals a bit. You may have to pack around fitting brackets anyway. Or use 15mm plasterboard + skim and take your time taping to be accurate.

Hi Henry. Welcome aboard. Plenty of experience here in renovation and garden buildings so ask away and chip-in where you can!

As above, graphite spray is recommended for locks I believe as it's 'dry' once the carrier has evaporated so doesn't get gummed up with dust and crap. I got some hideously expensive Interflon stuff, but only ever use it for locks/hinges/window mechanisms so it lasts OK.

I think I'd extend that downpipe above and drop it directly into the gutter too.

That's the stuff for the job. Thin is good so it folds round the battens reasonably neatly. It does fray so doesn't want a lot of handling, but once cut, stapled and clad, it's not going to be a problem. As @Russdl says, be prepared to to be spiked by it, even through gloves...

Not sure what other routes are available, but I wrote to our local councillor with a reasoned argument and asked him to call our (free go) application in. Before the scheduled meeting the LPA backed down so I didn't get the 'Parish Council experience'.

Sounds like you need a bit of a re-set with your builder. Looking at your posts re: drains and brickwork, I'd have to say his work looks a bit $h!t, and you're obviously lacking confidence and trust in him. Has he under-priced the job maybe, and is trying to claw some money back? Over-committed and trying to save some time? Bitten off more than he can chew in terms of competence? You've got a long way to go with your build, so for the sake of your sanity I'd suggest you need to get the relationship back on track or part company (as difficult as that might be either way...)

Yes, folded up behind the battens. It was on to blockwork with a cavity, so I didn't bother with a membrane. I'll be doing another one in the not-to-distant future on a timber frame and plan to slide the lead under the membrane. You can just see the lead on this:

I experienced what sounds like a similar relationship with architects and topo surveyors: jobs for the boys.... Was there a spec for the inspection? Not sure there's much you can do, but if it's that poor I'd be expressing my disappointment with the quality of the report, looking for an alternative builder, and maybe thinking about having a chat with whatever professional body the SE is registered with.

That's going to limit your audience a bit I'm afraid. Whilst we're lucky enough to have a number of professionals who keep us on track, this is more where the half-a$$ed amateurs hang out when we're not trying to rectify the last job.

Probably. Depending on gauge and condition, you can get through it with a spade and some determination!

Mini-digger to scrat it out, or just leave it in and work round it. I've done a bit of both; less disruptive to leave it in to rust away if you can.

Sometimes life throws the reset switch and gives you the space to re-evaluate and go again; well done for embracing it! Great progress on the house; love the manifold!

Ah...you're the one that uses them! Got a box full of unused ones somewhere I think if you need some 😄

It's not unusual to see some deflection in old roof timbers, particularly where the original slates or clay tiles have been replaced with heavier concrete tiles. Assuming there's no need to replace the roof, then maybe all it needs is some additional internal bracing to stop any more deflection.
