Dont chase this bodge ... What you cant see (because I haven't shown you) is the context. The photograph shows the flat roof area in front of the house - effectively a flat roof extension in front of a 'normal' house with a 'normal' roof. What is abnormal - is the quality of the block work (vertical misalignment mainly) - almost everywhere. So, as usual you are bang on correct, I need to think about the effect of any remedial work on the cladding for the whole house. At the moment, I'm thinking of continuing the 'window cill' remediation around the rest of the house. What happens at the corners? Exactly. The thinking (and thats as far as its got) we are planning to 'frame' the cladding with a bit of vertical 2 by 2 (chestnut maybe?) such that the chestnut protects the end grain of the cladding boards. The window cill will need to cap the vertical off too. (Diagram of the corner detail to follow) details correct at ground level ? Thats what keeps me awake (a bit - getting used to the stress levels now). As @Ferdinand says in his signature line, Cod is in the Details . Doing a quick sketch is my way of getting my head round the issue. Thanks very much for your support. Much appreciated. Ian

I was thinking that a Tupperware flashing would be cheaper, lighter and less hassle. Thanks @SteamyTea

Thanks for your post .Extremely helpful, lots to think about.

Be there. Watch.

If only, @Sue B. That would be have been so much easier.

Do you mean block out the battens to (say) 50mm anyway? So, with an 18mm cladding board, that would mean 68mm from the front of (some of) the wall.....

We will have to do that anyway. I'm saying that to get the battens perfectly level and straight up and down, I'm going to have to notch some battens to get past a few individual blocks. The blocks might well have been laid by a drunken gorilla. But, there's no point whatsoever in fussing about that now.

Thanks for the link (here). Exactly what I was looking for. CAD package: Mark 1 eyeball and remaining fingers. Vertical cockup : 35mm (at least) - an error of merely 10mm would be wonderful - we could manage that. The green stuff - (Evalon V) rests on an overhang of about 47mm or so. Since the battens are 25mm, and the cladding is 18mm (43mm) and the error is 35mm we are looking at a 75mm difference at the top. Oh dear, never mind what a shame. Know what? I'm learning reeeeally fast, like reallly reeeaaallyy fast.

Yes. The intention is to create about some 'reference' batons (4): perfectly vertical and level across the front of the wall (over about 10 m) The questions are What should the 'profile' (that protects the top of the cladding) be made of? (plastic / metal / lead?) and how far in front of the cladding should the cill / profile project? (10mm / 20mm / doesn't matter ?) Ian

Early in the build, before I became a nasty, snarling cynical bastard of a self-builder, I allowed the people who worked for us to get away with very unprofessional work. This episode (the first of a good few, I suspect) is about how to cope with a wall whose vertical and lateral profiles bear more than a passing resemblance to a banana. Everyone winces when I point it out. Everyone. Even that polite Mr @Stones when he dropped in (for a laugh) Can't take a joke? Shouldn'a started then should I. Here's the picture: Its our front wall; capped off with some Evalon V and a capping strip. Here's a diagram - a vertical profile. As you see from the picture, we have yet to clad our front wall. The drawing is a first stab at what to do. The problem is simple. The wall is so 'bent' that any cladding fitted closely to the wall at the bottom would end up 'overshooting' the capping strip at the top of the wall. So I propose to fit a window cill (- like) piece of wood at the top of the wall but under the bottom of the capping, and to protect that 'cill' with some form of metal or plastic profile. The end in mind is to create some wriggle room in which to compensate for the sloppy wall construction. The red line in the drawing is the intended metal or plastic profile. Is my design proposal sensible? If so, what type of profile should I use?

Thanks for the explanation. When did those regulations change?

Pheeeewww. That was close.

But, but , buuut you're a woman!?

Meat. Eat a huge hunk of ham. See what doesnt happen. Oh, and by the way, eat just a small amount of corn on the cob at the same time. (Used as a transit marker).

Pretty vents don't exist @vivienz. Its a new job for Supa @Onoff : add it to the list. For delivery 2025.....

Thats almost exactly what we did. Some cutting (but more infill) was needed because of the size of the Durisol block: it projected just a little too far in places. We also needed to match the pitch of one section of the building with (in this case) some external steels. Needless to say, with my luck, the two pitches did not match. Matching the two might not be important to you (the image appears to show two different pitches).

measuring ... thats why I didnt use them

Super cheap, super easy: thick bubble wrap, and a roller. Conserves heat quite well too. Lots of suppliers.

And a talent (on my job) for making 400mm errors.

Not sure that the core price varies that much (Lancashire), but transport cost do. And thats what makes the difference. Our 3 POSI quotes were within a couple of hundred: one company was happy to take responsibility for the measuements (which weren't that accurate).

And how often has Patience ( @Onoff's long-suffering wife) heard that?

Scene : local pub, Friday evening . Bar is full - buzzing chit chat , barmaid has a big grin on her face - all's well with the world. OnOff's mate: How's it goin' son? Mine's a pint. OnOff : Get on wiv ya, 's your round I think you'll find, matey boy OnOffs mate: Whatcha bin doin this week any way? OnOff: Yer....gorra special job on like, ................. (pauses for effect) .......... bin makin' a church pew The whole bar stops dead. All eyes on OnOff. Barmaid's spilling beer down her blouse with shock, beer's being snorted through a few noses, the pub dog's dreams come true - everyone spills their crisps at the same time. The pub parrot suffers spontaneous lock-jaw, and craps noisily with shock OnOffs mate: Seen the light eh, pal? OnOff: Naaaaah, but I like a challenge. And ( nods at the barmaid) wet T shirt competitions.

Use your own written style. Always. Cant you see the reader's eyes rolling ? In the context of a simple NMA application, who gives a stuff about the vision thing ?

And look at all your success despite - maybe because of - that.

I got so fed up with the kids ' ... needing to store ... ' ( or simply plonking rubbish in there without telling us) at our place that I created a section in our storage area called Death Row. If it was still in there after six months , I sent the offender a text. Still there after a further six months - skipped. Not one of them has ever complained - they dont need their A Level notes any more.... funny that innit?
