Thanks, I'll give that a go.
A first glance I'm surprised a block has greater insulating value than all that PIR.
It'd be thinner than the width of the cavity, but that's not much I agree. Still looking at mainly achieving a lighter structure.

If they matched the existing bricks, I don't see why not.
If it is just a single run of wall then you will need to buttress it. If there is a right-angle joint then triangualtion will provide the necessary strength.
If this is going to be habitable, then building control will want to see plans with calculations for structure and thermal performance anyway.

None of the architects/builders has raised that as a concern, rather than sucking their teeth about the cost of the matching bricks and depth of foundations required.
So how will the bricky 'rub' the joints if it is bang up against a fence panel (presumably not yours) ?.
If you are within 2 metres of your neighbours walls then the party wall act applies. be careful.
Smaller is better with U values (not R values)
Fair enough - assuming they knew that they were supposed to meet the necessary standard without access to the external face of the wall.
Not if it is timber framed which it might as well be - you need 4" of celotex to meet regs and 4" or 6" of timber will provide enough strength for the brickwork.
Hard to make a fair job of the brick outside face when its rammed against a fence tho

It would have right-angles at both ends.
I know, but trying to get some rough idea before spending a lot of time on proposals that won't fly (or indeed caving into unimaginative suppliers who want an easy life).

Whatever. The point I was making was the ability to insulate.

If I had my own way I'd put up some external cladding that looks like pebble-dashing, which about half the houses round here have anyway (plus others with painted brick) and you can't see the surface in question from the road. But one thing my current suppliers agree on is they think the conservation officer will insist on "matching bricks".
Maybe I'll have to wait and see what comes through from the planning people.

Round here the planners want half a metre these days.

Any particular reason given? It's not as if there's any of my neighbour's *house* anywhere close (which could perhaps be a noise/fire issue).
I know someone who built something similar last year, in a local conservation area, and it was almost as close - and that time the neighbours house was only three inches the other side of a similar boundary fence.
There is something called the 'terracing effect' where rows of 1930's semis all have side extensions and end up looking like a row of terraced houses. The planners don't like this.
More of a problem with 2-story extensions though.

I'm aware of that. Indeed a house opposite the one I was living in about fifteen years ago was refused PP for a two storey front-extension (replacing the garage at the side) for that very reason. Not that a row of randomly designed five bedroom 1930's detached houses could ever look like anything I'd call a 'terrace'. It didn't help that the next-door detached house was built right up against the plot-line, though.
However, the build I'm investigating today is at the rear, and most of the street is already comprised of houses built so close together at the front that they might as well be a terrace.
I had a house about 30yrs ago (which was perhaps 250yrs old on the village main street) that I never could stick in a box. The best I could say was that it was a detached house built touching the next-door detached houses. There were no party walls, we all had our own. And the line of guttering at the front wasn't even the same height.
