What was the condition for the fence i.e. did they just want to know the details e.g. scale drawing with materials etc? They must of had a reason for this. Were your approved planning drawings lacking in detail and they want to mitigate concerns from neighbour? If you just want to sleep easy then just put in your application to discharge the remaining conditions. Just put in your application the details of what you've installed but without indicating you've actually installed them. If it makes you feel any better I'd purchased our windows/doors, cladding all before discharging the condition of prior approval. Risky - yes but then I didn't deviate away from what was on the outline planning drawings i.e. colour, design, shape etc. The only value add from the planning drawings were the window/door/cladding section details. They never contacted me or asked for physical material samples. From the LPA's perspective another £75 = cheers easy.

Every LPA is different but our experience was the planner wanted to keep as much as possible of the old building whereas we wanted to remove as much as possible. Our LPA were dead against converting our building in the first place so our approach was to get full planning permission established albeit with a god awful design that retained just about everything we hated about the shed we were converting just to appease the planner. Once full planning was established we then went through a couple of S73's to refine the design to something more akin to what we wanted. Although S73 is effectively another full planning application its basis is on the principle that the dwelling already has planning approved for a conversion, it removed some of the conditions e.g. retain/repair the fibre cement roof and metal sheet cladding etc. We managed to get it back to just retaining the steel frame and the existing concrete slab to retain its conversion status. The slab is hidden and the steel is embedded into the walls so you can't see any of it at all, bonkers and a waste of everyone's time and my money. Your approach will no doubt be dictated by the officer and your LPA. There were a few benefits to conversion in terms of BR but we aimed to set the bar higher than that e.g. we used new build U values as a minimum.

If you wanted to convert it back to residential then you'd need a change of use first which, without being in place, would probably scare most propestive domestic purchasers away. You say it would not be commercially viable but have you tested that i.e. advertised it as a business for sale etc. I'm anticpating the planners may want to see that before permitting a change of use but best to talk to them. A pre-app may give you some pointers.

if you're coming halfway up the slab I would've thought a few holes and some rebar to tie existing foundation and slab to new pour.

tend to agree, my experience with wood burners is trickle events just don't allow enough supply air. Just opening the window slightly usually provides a near instant combustion improvement and kindoff proves the point. Something to think about if you're not having the fire lit much is whether there's a risk of mice in the floor void deciding to nest in the pipe? If so how will you provide a louvre or the like to prevent that?

A drain at that height behind the wall sat on pea gravel will do next to nothing. The water would have to be 450mm deep before it can make use of the land drain, you might catch a bit of surface water draining from the top but water will always take the esiest route which will be past your drain, through the gravel and continue sitting on your foundation. What about lifting the level up with concrete, then allow for pea gravel to bed your pipe on then membrane to stop all the mud blocking it up, reinstate gravel, wrap with membrance and fill with soil - plenty of pics on tinternet. Your puddle in front of the wall - is that just where you dig out for foundation? would not reinstating with concrete sort that out?

But I used perforated sheets and cut them to my own length/width to suit, can't remember exact spec of gauge/hole size but stainlees and along these lines https://www.fhbrundle.co.uk/mesh/perforated-metal?via_sb=true Whichever you choose I would look for something with some rigidity to it otherwise it will sag between fixings and also if its too light a guage the fixings like screws will dmage it hence why some have used staples.

Don't think there's any requirement to box in, just need to maintain distance to combustibles. I think you can get the aesthetics for the firestop and vent like so

Dektite grommets for the external seal, as bove. Red and black rated for different temperatures I believe, red is higher.

I'd be inclined to contact your local fire officer, they're usually very helpful.

We have Norrsken, supply only. We found the price mid range, most things become a balance of quality v cost but we've been really happy with them, well mostly. The timber and alu clad were beautifully finished, the hinge mechanisms lovely and smooth in operation. Pre-sales were very helpful, communications up to and including delivery really good. Not so good - The window handles are cheap. The moulded plastic coating has broke on one of them already. I can't remember if they offered the option but I'd go for something more robust. Installation support, typical drawings, etc were non existent. I really had to push to get information and what I got was very, very basic. This wasn't a big issue for us personally but may be for others. Would I choose them again, absolutely.

I don't think there's any need to leave it at 6bar, it's really just to test the joints above their normal operating pressure. I dropped ours down to 1.5 bar when they poured the screed and just monitored it. It went up to 4bar shortly after pour then dropped back down to 1.5 after a few days if I recall.

Yes I have it Russ, plus the stapler as well If passing anywhere near Hereford can meet up or post.

Lol, too late in life for that...

Likewise, I prefer to keep the wood fresh looking.

Be aware that this will still silver. Vastern have weathered panels on display outside.

I used Plasson throughout our 32mm supply, sourced via JDP as well. That Plasson stoptap in your picture has been in my plant room under 10-12bar pressure for over 2 yrs and no issues.

If you're set on buying from abroad then some of the Polish manufacturers may be worth a look, debesto, fenbro, etc. Debesto certainly have a wider range of brands.

I had some samples of Ayous, thermally modified, and liked the look of it but wow is it brittle and it also marked very easily. The grain pattern didn't really suit the look we were after in the end but that's a personal thing. It was a reasonbale price circa £6.50/lm if I recall. We ended up going for cladding from Norclad. Its A+ GRADE Brunnea treated Redwood, very few knots. And as its treated it's not as brittle as some of the thermally modified stuff. I'm sure there's some info on Norclad site about additional fire treatment as well. Note Norclad are part of Arnold Laver now who are in turn under the National Timber Group. The reason I mention this is if you wanted to use Norclad then your BM may have accounts with AL and/or NTG so you might be able to negotiate a better deal.

Hammer tacker

Similar to others we just used 35mm metal boxes, which work nice with 25mm batten and 12.5 pb, screwed to webs.

The expanding tape is amazing stuff, often with a price to match! By the time we're finished I wouldn't be surprsied if we've spent £5-600 on compriband, foam, etc around our doors/windows. How will you apply this very wide tape into a small gap and press it onto the frame? We had mostly 10mm gaps and I found even a 20mm deep tape to be quite fiddly to install, but then the reveals on ours are very deep which didn't help. I found a scrap piece of thin, soft metal that I bent to shape to help press it home against the frame.

Couldn't you use a narrower compriband tape and make the difference up with air tight expanding foam? Both more readily available......and possibly cheaper.

We purchased Norrsken. Very pleased with the quality of the windows/doors themselves. Though I am slightly disappointed with the window handles, broken one within 2 wks of fitting them already. Admittedly only a tenner or so to replace but then maybe that says it all. We only found out they were cheapos afterwards. Would've liked to have been given the option to specifiy better quality. Despite this would I buy Norrsken again, yes definitely. I would highly recommend you visit some showrooms, it really gives you a good sense of the difference in appearance, quality of the products.
