Can it only be occupied as a holiday let? If not, tell them to sell it!

I'm attempting this at the moment (when it's above 5 degrees). The plan is lime putty for smaller areas and lime putty/sand mortar mix built up in layers for larger areas. Then a final wipe down before final lime plaster layer, then lime primer, then breathable paint.
Getting the mix, moisture level, temperature and ensuring you're patient seems to be what others recommend. YouTube videos look easy enough, etc.

Yep, I've looked at similar options. Hempcrete is out (mess and weight). I originally assumed cork would be too expensive (perhaps not if unfinished). We already have a base of semi-decent lime plaster and we don't mind working with lime plaster/paints on top.
I contacted Pavatex and they stated that reducing U-values beyond 0.4 was inadvisable as would have too significant effect on rate of drying of the (exterior) wall, hence frost damage. This seems to be confirmed by Jospeh Little in Breaking The Mould:
"It seems reasonable to deduce from this that once driving rain is dealt with internally-insulated walls appear to work best with less insulation than 0.45 W/m2K"
https://www.buildinglifeconsultancy.com/content/breaking-mould-5 (link not secure)However, I wondered if there was an alternative to accepting a worse U-value (for IWI) by reducing humidity (heat recovery from bathrooms for example) as the improved interior environment might provide better external wall performance during dry spells?
Or perhaps I need to fixate less on U-values...

@TW I'm talking about a heritage-style solid wall installation with no vapour control layer. So a fully permeable insulation system using wood-fibre board and lime plaster that would work with the walls thermal mass (not against it).
A non-permeable insulation layer with gap would be pretty standard, but also leads to overheating in the loft, trickier bridges/returns (around sash window boxes) and might mean the wall/timbers achieve 20% humidity in poorly ventilated areas regardless.

Although it perhaps seems 'obvious'... they haven't seen an increase in viruses in water translate into a big increase in transmissible viruses in shellfish (yet?).
Oysters/norovirus is the classic example, the water/environment/oysters contain low-level norovirus, but there's been no data to suggest the norovirus risk from oysters has actually increased (it's stable).

Consider talking to a financial advisor as they'll most likely save you time and money.
Typically up to £85,000 per person per institution is fully protected (FCA).
I'd either start with one of the big providers (Vanguard, Hargreaves Lansdown, etc). Or one of the easy-access ones (Nutmeg, Nest, etc).

You can retrofit any building to Passivhaus standards. There were a few players trying to do just that with huge outer envelopes ~10 years ago, but surprise surprise they didn't get much traction in the UK.
If a key driver was reduction in energy consumption, why is there a wood stove and exhaust poking out the roof of it? Fail.

Any advice for hunting lead flashing issues?
I'm assuming some bricks are sponging water from one side of the roof as the damp stain appears lower down the wall (halfway down in the loft space). I can also see what looks like badly overlapped lead sections.
Anyone got any tips? Or do I have to climb on the roof and randomly investigate?

This was my fault. I had to move a weekend trip to do some DIY in Devon because we played last Friday (rearranged game). Sorry, I love Doodle, but we filled that in on 15th November and I only heard about Saturday being a possibility earlier this week (3 weeks later).
I can do any day really, but usually need a bit of notice. A Doodle 'option' is not a confirmed date to play, etc.
