Nudura do an insulation board that has a batten built into the sheet, so imagine a 75mm sheet of insulation with a 35-40mm batten buried into the insulation, you would glue and screw this to your ceiling. I was very impressed with it, but didn’t use it as I needed over 300m and it was getting ridiculously expensive, if it’s a smaller area it might not be to bad I think it was about £45 a sheet.

Shouldn’t this be confirmed in a nailing schedule drawn up by the structural engineer. Who has designed the frame. I built my last stick frame on site, you will have bracing walls that should require a different fixing down method as they do a different job. It all depends on what functions the walls are performing.

Morning all. What type of material should a CU be mounted to, does it need to be non,combustible im just putting up stud walls and it would be easier to install whatever I need into this cupboard before I build any more walls. Back wall is clad in OSB to stiffen it and for screwing into, what should I put on top as a finish. Fire line plasterboard fermacel glitter. @ProDave @Nickfromwales @Onoff

Plenty of cockups here, onwards and upwards, don’t beat yourself up over it, not many on here doing all the work themselves.

There’s a strange bloke on here called @Patrick he does this sort of thing. Just don’t ask him to cut any trees down for you.??

Are you a developer or just a bloke trying to make a few quid. Have you checked your CIL liability before you go in all guns blazing. Have you got planning approved before you knock it down.

Why not break the job into two bits, fabricate the first floor and standard details then bring it to site and fabricate the rest on site when it will be easier to get exact measurements.

Watching this. my 5m ceilings are giving me nightmares wondering what an earth to do with them.

Thoughts on that, it will be ridiculously hot in the summer and freezing in the winter, just like a cheap conservatory.

Off topic @SuperJohnG any more pics of your smoker bbq thing. And how do you use it for that chicken. Cheers.

When we lived in oz I had a 6m multi stacker, so 6 panels 4 that slid out of the way leaving a 4m opening. When we started designing this place I thought we would have the same, but then I thought this is England not Australia, how many days of the year will I have all that door open. The answer was not often so we settled on smaller openings but picture windows looking at your location I will be surprised if you ever open it ??

I’m still not sure what your trying to do but, what you need to be aware of, if you hang a joist of another than the first joists load will increase, you normally install two joists side by side bolted together to increase the strength before joining the new joist onto it. I think it will I’ll be a case of there’s no reason you can’t do what you want ,but you won’t be able to work it out until you strip of the trim covering the stairs and strip a bit of decorations back to see what you have underneath.

I’ve no idea, some dimensions might help, and a picture.

I used architouch on my I pad, I’m a complete technophobe and I found it very good, subscription needed, has probably cost a couple of hundred over the last two years I’ve been. Building.

Have you not got a structural engineer, you will need one to size the steel according to the load to be carried and the spans involved. I have had two engineers at my place the first one did everything for the house, then I suddenly wanted to change an opening so gave him a call, he said he couldn’t do anything for a couple of weeks, so I walked into the local structural engineering co in my town and they did a one of job for this new beam for a couple of hundred quid.

What is this for, a floor slab? if so it should have stone of some sort heavily compacted, then a sand blinding compacted and screeded flat, don’t be thinking concrete will flatten it, it won’t it will follow what ever shape you have left. Now is not the time time to be skimping on a couple of hours work.

We used 4 pairs of glass suckers to lift up £5000 worth of glass, how long are you planning to keep it in the air?? is this bathroom going to take as long as @Onoff are you planning to keep it suspended in the air for a couple of years. If not stick the suckers on it and pick it up, c,mon it’s not rocket science. ???

Lean over the cavity every night and check with a torch, knock any off with a bit of stick. You shouldn't really get snots with a wire tie.

Ask them to install coring holes so the cavity can be cleaned out.

Buy your own materials and do it yourself. What is the reason for wanting this for an extension. My thoughts are that you will create a lot more agro than you need, the difference in materials from the old to the new will be a pain all the time.

That’s cheap loads of people on here paying double that. I didn’t have one as I was going to pile it anyway, why not phone a few companies and just ask for a soil bearing test, you will probably need to do a site strip so your down to bearing soil before they come out.

Rockpanel looks nice, bit expensive but no maintenance. I used on my last place cement sheeting boards that had plastic joining strips, made by James hardy. Its the details like this that this country lets you down, loads of other options available abroad, but over here if you want different it’s going to cost you.

Or as Simon pointed out, remove the two vertical timbers in my drawing and drop the stud wall down to fix the rim board to, this will tie things together nicely.

Don’t like that idea pain to build, where would you put insulation? not really understanding how the joist is attached. One question that would really affect how you build this would be if you want to leave the down stairs room Undisturbed, with my first version you will end up cutting into the downstairs ceiling, not a problem if your ripping it all out.
