£516.99!!! Real men make their own:

It's definitely a niche thing...

You can either form them yourself like I did: Or buy them ready made like @pocster has just done. (I was limited on depth).

Could you move door D4 to the right so it opens towards the window? That'd free up a square corner in the bathroom for a decent sized shower. I'd still square off that V though. With hindsight I might have had the wc on my squared off corner and had a walk in shower in the adjacent corridor through the old doorway!

Best idea ? That V shaped internal corner is going to be a really useless space.

Don't have a tray at all and tile to falls? Where's the drain going?

I'm sorry, I'm not familiar with those terms.

Lemon juice...

A big, central steel (red), off the the existing (red) RSJ across the opening was my initial thought. Then new, deeper (black) beams was the plan. I know the concept but have no ideas how to calc the sizes.

So write to PayPal stating that.

400, 450, 600 centres? Flitch beam spacing or was there just the one? I'd need up to 9 such beams: Just realised there is/are flitch beams in this house now. Didn't put two and two together! I've the dormer extension drawings that I got (as a freebie) from BC a couple of years back.

Ta. What centres?

Armageddon!

I don't know if you have the time to investigate but my mate bought Spax (decking) screws from here in bulk. Even with shipping they were miles cheaper than he could have bought them in the UK. Not sure how / if the whole Brexit thing will have affected things as it was pre this: https://www.klokow-gmbh.de/

If you've any old style Jenolite liquid, that contains phosphoric acid and works too but you can't do patches. It's the whole lot or nothing.

I could have picked you one up with myxomatosis this morning and posted it to spread the love. We've got it locally as happens periodically. Not pleasant to see the poor little sods all blind and emaciated.

Wouldn't the angled face want to be a glazed face?

Flitch beams...I never knew they were called that! Wondering if x2 9"x3"s sistered, with a steel plate inbetween would span 5860/6060mm and negate the need for supporting steels. I came across this flitch beam calculator. Worth spending £20? https://www.yourspreadsheets.co.uk/flitch-beam-design-to-bs-5268.html

I see you lurking & mocking my tiling @pocster Surprised it took this long, all this talk of open bottoms and semis! ?

I've got it...how about a gabion as a pedestal? I think it'd look the nuts.

Go for a tiled box I would. Tapering in on all sides so you can get (via your feet) closer in to the sink. ?

Yes it was, thanks. Thinking now though, that a clear, reinforced tarp might be better for my needs.

Do I recall on here a little while ago someone saying they used clear, scaffolding "tarps"? Super strong and obviously let light through. I might even consider sorting my roof if they're available big enough. Was thinking to put some eye bolts on the dormer faces to tie the tarp to.

Even a letter from them, confirming they sent the certs to A N Other online seller might be enough to placate the inspector.

Door Stop Direct will almost certainly have a copy of the cert they sent: https://www.door-stop.co.uk/Blog/Post/door-stop-u-value-certificates-validated-by-bre You might have to pay to get a copy mind.
