Ta. CAD concurs at 394.3mm on 2 sides. I get 9.49deg on those sides & 13.3deg on the 550mm side. Making some supports to go inside the mould:

I veed the Celotex where the pipes run in my walls. Then foamed and fitted the top section of the V back in. Foil taped over the top.

9mm on the roof might even sag over time and you'll end up with washing up bowl like depressions where the water will sit.

Any vcl in the wall makeup? 9mm on the roof will be crap to walk on even for maintenance. I've 12mm on one of my flat roofs (I didn't do it) and that's a bit springy even at 400mm centres.

You can't make an omelette without breaking eggs. Worst case inside, your re plastering looks a bodge. You could plasterboard the reveal instead or even line it with timber. Worst case if you remove stuff from outside, it leaks.

You usually want a shoe on the bottom of the down pipe to direct it away from/off the pad and down the slope. In this case you might need a 112 or 92.5deg bend then a short length of pipe to do the same. Pretty sure you could knock something up from an old bit of ordinary gutter set at an angle so the down pipe just sits on that. Any old bits of lead, another possibility?

Menopause?

Got a bit of my stuff from British Bathrooms as they were the cheapest for what I wanted: https://www.britishbathroomcompany.co.uk/ One time I had to chase a delivery but it all came through in the end.

Wonderful stuff it is!  I dip wire ends in it before I put crimps on, I dip crimps in it before I push them together, I even dip stripped wire ends in it before I put bootlace ferrules on. I smear inside limit switches over the screw terminals. I dip coax in it before I screw F plugs on etc. Stuff lasts indefinitely outside/in harsh environments on the car etc. But I've run out... Need some at home over the weekend. Would plumbers grease do the same job?

Cheap too! Look at the stupid prices here: https://ukcaststoneonline.co.uk/product/flat-pier-cap-550mm-x-550mm/

Basically this fag packet sketch drawn on a lurching train! The key really is 4 triangles as aforementioned. The angle where the sloping sections meet the vertical sides of the mould, no problem. Just need to figure where the day A edge meets B edge. Fire up the CAD! (Just realised I haven't shown the drip bead mouldings).

The pillar is 2x2 bricks so 450x450mm. I want a 50mm overhang around the edges with the drip bead say 25mm in from the edge. Overall height 130mm so a 65mm pyramid sat atop a 65mm slab. Just got to calculate & cut, 4 precise, triangles that will butt up and glue to each other to form the pyramid.

I've hammered mine and it's been great, the Makita powered Chinesium mini chainsaw too.

Thanks. I think I did start to model it in AutoCAD...might have given it to my lad to model in Fusion...can't remember. Sometimes even if I can do something easier/quicker I'll give it to him to excercise his CAD skills.

I can't help thinking...buy a commercial, metal door and repaint it! Meant to take photos at work of the edge/corner details but this might help. Ours are all interlock seamed:

You're correct. I'm getting confused! His pallet shed was a separate thread!

And that's where you're wrong! ? They can look alright but there's a bit of compromise. I built one with the nephew. The key is getting the same pallets ideally. Even then you might find a tub of Screwfix's finest plastic shims a great help. Decent square base. Then a 4x2 sole plate all round, itself sat on a strip of dpm. Butt them together and screw. You will need some reclaimed bits let in to and screwed to the bottom line of pallets and the ones that'll sit on top. You'll have to cut/adapt pallets for doorways and windows. Pallets were painted as it progressed. Membrane the whole lot outside. I left him to it to do the roof. You need to let in sections to form a wall plate at the top. He clad the inside again, with pallet wood: Clad. In this case various trimmings from a DIY lumber mill. Painted & with "Dad" sign and bird box! Reclaimed front door. To be fair this was my nephew's first proper DIY project on his own and I think it came out alright. When he started a square was a novelty, now he uses a bevel gauge! I still catch my head on that corner of the front fascia. Mind you he's a porg. Make or buy a pallet buster btw! https://youtu.be/cvG5pe62DsE I think @ProDave built one too essentially to mount his DIY PV array.

Some of it! They say the camera never lies...it does! ? Tbf this is one of the better areas but thanks anyway.

Not the same stuff...FloPlast Miniflow? I was expecting him to shop around price wise but maybe not...

Difficult to see under there tbh...it's a dark photo. Cut down, re-drill and paint the cut end and drilled hole an option. Multi-tool the top of the wall and let them in without cutting the bracket maybe? Could you not just cut some timber blocks from say 4*2 and screw on from the inside. Cut them at an angle so they butt up to the roof timbers. Then affix the gutter brackets to those?

Crap attempt at marking up the pic but if you look underneath the side overhangs can you see the ends of the angled roof timbers? What the fascia board butts up to...

I'll get back to you.

I'm going to make an upside down mould like this if I can figure the "pyramid" maths to cut the bits. I'll then fill from the top and vibrate it so it hopefully fills the voids:

Not yet filled. Now white silicone.

Forever White silicone. In part as the complete bath end panel and one side panel can be removed for access.
