@pocster, are you having a pumped liquid screed at "only" 60mm?

My two frames were a bargain £100 the pair. Older models so deeper but work a treat. Geberit instructions are good too. I was lucky in the frame was sited over the old blocked up doorway that ended up 2" lower anyway than the main wall. Over a 3m wide wall not one stud is the same depth range from 90mm to I think 145mm. In part to square the room off and also to allow depth for the pockets as well as wc frame. The studs are concrete screwed to the wall at 5 points minimum. The rears are packed with timber where the screws are then everything foam filled. Geberit instructions are good too. Typical drawings: There'll also likely be a video for whatever frame you get, e.g:

What Geberit cistern are you planning? Stud depth is on the instructions.

Well fair play to Susan ?: https://www.gumtree.com/p/plumbing-central-heating/heat-recovery-unit-fully-working-home-made-unit-size-80cm-x-70cm-x-33cm/1336403114

Fully agree about pir taking up moisture. But eps...the stuff they make swimming floats from???

Where's the fun in that? ?

If you can find me a Screweys with one of these in stock I might! ? https://www.screwfix.com/p/z1c-ds-65-14-3kg-hex-shank-breaker-230v/9158v

So I've got compacted Type 2, sand blind, 25mm eps, dpm then 150mm of pir. Are you saying I should have had a dpm under the eps?

Take this passive build for example. 300mm of Peripor polystyrene straight onto the compacted sub base - no membrane underneath:

What's GF?

These silos, are the ICBMs still in them? ? Oh, and welcome.

I wondered. Read some stuff and the water take up of eps is minimal.

Can you introduce new fittings easily enough? Slip couplings can help.

Got all my Geberit from eBay, Gumtree & Preloved. Couldn't afford new! Thinking about I'm sure it was @PeterW gave me a link to an online catalogue that made it much easier to decipher compatible part numbers. Love Geberit but wtf do they mix mm and cm on the same drawing?

? In the cupboard...I'm listening. We have a cupboard though it's on two internal walls. What sort of unit were you thinking? Would it mean a long 4" pipe out to the soffit? Rather than a louvre door how about a vent in one of those tiles above the door? Or the top full tile above the loo on the cupboard side? (Tbh I'd still rather make than buy!)

Yep. Sight lines on protected views, listed buildings etc. Latchways fitted right works really well but the onus is on whoever is accessing the roof to clip on. Fit a handrail or screen and there's no worry. Years ago was on a big bank job where the roof was covered in God awful looking plant. To tidy it up they erected a louvred screen wall around the whole lot. Tbh the screen wall was only as high as the tallest bit of plant and it tidied everything up so much. There was a right fuss made over them compromising the sight lines to St Pauls which was b@llocks.

The time has come! Currently I have no ventilation in the bathroom other than the window. The original plan was to use a wall mounted, single room Ventaxia but tbh I think they are bloody ugly! It was @Ferdinand's recent thread that put me onto one of these: I can mount this up in the loft which is pretty much a blank canvas. But where to put the vents as in there are 4. There's two go outside as I understand it and I guess they just have to be a certain distance apart. Planning those in the soffit. But the two inside??? In the interests of keeping some symmetry I was thinking maybe one vent where the green Post-It is high up on the wall behind the rainfall head. It'd go through that tile into the void behind the mitred corner then up through the ceiling to the unit in the loft. I fancy the challenge! Then the 4th vent, maybe in the ceiling outside the bathroom, again where the green Post-it is? This room is next to be gutted much as bathroom was, as in ceiling replaced, floor dug down etc: (Temporary bathroom door btw). Or inside the bathroom? Big question, the MVHR unit and pipes in the loft: The loft is cold and uninsulated. Do the unit and ducts need to be "lagged"? Thanks

I have this Humidex 7 dehumidifier I got as a freebie years ago. Still works fine (or did). I wonder if this would be suitable for him? Too heavy though for me to train it up to him. HSS want £130 a week hire at a quick glance for a dehumifier. Spec on this I think is 10 litres per day:

Tazer?

Read Part K about if kids can climb it etc.

Edit: Comments withdrawn. Personal apology being made. Don't ask.

It does imo. We can cherry pick to our hearts content: "Guarding of areas used for maintenance For all buildings 3.4 Where people will use the stairs or ladders to access areas for maintenance they should comply with one of the following. a. If access will be required frequently (e.g. a minimum of once per month): follow provisions such as those suggested for dwellings in this Approved Document (see Diagram 3.1). b. If access will be required less frequently than once a month: it may be appropriate to use temporary guarding or warning notices. The Construction (Design and Management) Regulations 2007 and the Work at Height Regulations 2005 give provisions for such measures. 3.5 Use signs as specified in the Health and Safety (Safety Signs and Signals) Regulations 1996". Also: "For areas where access is required only for maintenance, greater care can be expected from people and therefore a lower standard of provision may be acceptable". Working at Height regs are referred to also. The full Part K doc: EXT.Approved-Document-K-Protection-from-Falling-ENG-2013.JMCN_.v1.200417.pdf Is access required perhaps to these areas for periodic window cleaning, maintenance of pv panels etc? Agreed though it needs a frank discussion as to why these requirements have been specified.

He has rigged a temporary shower curtain.

Part K applies in terms of the broad need for protection. Guessing these areas are accessible for (roof) maintenance only? Consideration might be given to a suitable, unobtrusive, safety harness eyebolt(s) mounted on say a wall whereby you could attach a retractable fall restraint block upon accessing the area.

Agreed but some LAs kick off about visible handrail. Know to our cost where we fitted handrail instead of the spec'd L'way and had to rip it all out. I did years ago manage to fit handrail on a building with sight lines to St Paul's by arguing it was the safest option. Does the @Adam2 want handrail?
