So this where everyone has been hiding. Hi I'm Graeme and was part of the old forum. It's probably at least a year and a half since I posted or questioned anyone about my Passive build on the South Coast. It's taken this long to get planning and we are still waiting for certain conditions to be removed. I won't say too much but Arun Council will not be on my Christmas list.

Not to worry, yours are stationary.

should be easy enough, Is it one of the new ones with the 2" foam surround, If so I cant help with that part but the rest should be mainly held together with screws, there are only 2 clips that come undone fairly easy that i know of, at least on mine there were

Hmm, the images hint at passivhaus , or near PH design? Right? I love the idea of the light well. Get the window detail right. How are they going to be cleaned? The internal loo might well be a problem. Move it to where you can flush it with fresh air perhaps? Looking forward to seeing details as they emerge. And before I forget, welcome. Ian

Root issue: there isn't one: there are many interacting with one another. High Wind and higher gust speeds. Lack of experience. Failure to communicate. Assumption of common sense. The pressure to take on too much work. The two other stakeholders would put a different emphasis on it. One would say; use your common sense and don't build too much height before pouring. The other would say; but you didn't tell us that. Had the wall been poured, and the concrete set, there would have been no problem. It is crystal clear to me that neither builder nor producer has been trained to communicate well. They do what they do. They don't listen well. They don't express themselves clearly. They rely on what is called common sense. But common sense isn't universal. Add a trusting (yes, naive - but not so naive now) Domestic Client , unseasonal turbulent wind coming directly out of the east (very rare here), a builder who is trying to do too much, and you've got an issue. And here's what's happening next. The replacement blocks are arriving tomorrow morning, (sensible rebate on that) and the builder is going to rebuild for free. Exactly as @Declan52 said it should last week.

@recoveringacademic Local topography can be so important when it comes to wind! I grew up on the north west coast a little further south of you and know how bad the prevailing wind off the sea can be anywhere near the beach - you'd normally expect the danger to be from the west but your photos eloquently demonstrate the problem you had that night. Did you ever read about the 1960s failure of the concrete cooling towers at Ferrybridge?: https://matzagusto.wordpress.com/2011/12/14/vibration-damages-towers-case-ferrybridge-cooling-towers-collapse/ It's a prime example of the dangers that can be caused by wind being channeled and the unexpected loads that it can create on structures.

Good point, if you think that the J1772 EVSE standard may change before you get around to buying an EV, then just putting a hefty cable in place is probably a better bet. In my case I already had a plug-in car, plus I'm pretty sure that J1772 will be around for another decade or so, so I fitted one standard J1772 tethered cable EVSE unit plus one fitted with an IEC62196-2 socket, as fitted to public EVSEs. The argument in favour of fitting an EVSE now, though, is that they are still subsidised. Whether or not that makes sense depends on how long the subsidy is likely to continue. If you want to future-proof, then fitting an EVSE with an IEC62196-2 socket on the front, rather than a tethered J1772 charge lead and connector, guarantees that the unit will be OK for the next 20 years or so at least, probably a lot longer, as the IEC62196-2 charge point infrastructure is widespread in the UK and Europe. Given that the IEC62196-2 socket has been adopted as the standard fixed charge point connector, if, for some reason, EV manufacturers decide to bin the existing J1772 vehicle connector, then the EVSE will still be fine, as the IEC62196-2 connector supports single or 3 phase charging at up to 32A per phase (but realistically, home charging is very unlikely to ever normally exceed somewhere around 7.3kW single phase, because of local grid limitations). 7.3kW equates to roughly 25 miles range per charging hour at the moment.

Just an idea, but can expansion slots be cut in and then finished over?

Yes but which Technology and Why is it complicated? I am not quite with Jeremy and others on this. I think, can probably prove to most peoples satisfaction, that where we are now is not a particular indication of where we will be in the future. This because although the future itself is not predictable the Soft systems (humans) perhaps soon to be aided by AI that underpin development are predictable in their unpredictability. Although high costs are indicated in moving from one technology to another and vested interest is a serious challenge to change we have, as humans, often demonstrated that such changes when provided with enough pressure (push or pull) our ability to make such changes. So from the time the flint knappers were wiped out by the bronze using hoards to the railways replacing the canals, to the Jet engine replacing the piston engine (and the attendant move from wooden air frames to metal ones) and so on we have demonstrated our propensity to move quite quickly and find the money. Many loose their proverbial shirts while others clean up (pardon the pun). Was it ever thus?

You could always use.... On second thoughts, I'd better not open that can again

Well its just my Dad and myself. He draws and measures, I cut and fix. Thanks for the compliment. No professionals on site yet.

does the top have a plasticky coating on it?, usually grey with a slight texture to it if so I think this is what oz is talking about and should be ok at its core, our managers keep making us put it down before the roof is on because it saves on temporarily boarding the joists for the bricks to build the second lift, we moan like hell about it because as you can see it does swell at the joints and any open cuts around stair wells, the swelling will probably be taken out by the underlay if you are having carpet but that still doesnt make it right, sanding it flat is probably the way to go. from the way it has soaked in in the first picture i would say they are not those boards and are just moisture resistant, it might still be ok but if I'm honest i wouldn't like to put my name to it
