I can’t see, but is your conduit coming straight out of the slab and into the wall or room?

It is indeed - top right. Intending to have an integrated shed with a fuse board in there.

I don’t think you’ll have much of an issue, but I ran various sizes of flex conduit. If you have longer spans that aren’t tied down there is a chance of collapsing the conduit during a wire pull. I’ve had this happen twice in my attic. My long runs in concrete are perfect and my longer runs that are clamped down to studs in the attic are good too. It’s just the free-floating runs in the attic that haven’t worked out.

That’s a good headsup about the collapsing conduit, cheers I’ve used external rugged conduit, so it’s pretty tough stuff, but when I come to internal, I’ll definitely take note Thought I’d do a little video: https://youtu.be/k6a7Ll3-79M

Just a little update in video form

Just a little update, nearly half way there with the block work

Another little update for ya’ll

Here’s another view, from where I’m hoping I’ll sit

Could splash out on one of those fancy Corning optical TB3 cables that Linus used for his office.

Ha, you’re not doing two blocks, insulation in between like my neighbor is doing for their extension:

How does U value math look like for what you’re planning?

ChrisA · June 8, 2021, 2:55pm

Oooh, I did think about that initially, but as a precaution I would configure the workstation to be in the attached shed (insulated and vented of course!). Well, that’s the intention, energy permitting

ChrisA · June 8, 2021, 2:58pm

I’ve gone for single skin block to reduce loading and depth of foundation. Using EWI 4 inch, then batten and weatherboarding. U Value should be around 0.20-0.25 for walls, 4 inch floor insulation and 4 inch over joist insulation sandwiched between OSB, 4 layers hot felt roof finish.
