    10mm holes within 50mm from top of joist

    Thank you all for your replies! It has helped me a lot :) I think an access hatch would be difficult, due to how i am doing the wiring, i have attached the "plans" to try and maybe show how i need to be able to access the edges of the room at minimum. As for alignment when walking around...

    10mm holes within 50mm from top of joist

    Haha yes it will be carpet tiles, found some relatively nice ones actually, much better than they used to be. Putting a single layer of mlv down under the tiles given that it's the theater room. I'm running the electrics for downstairs inside the 1st floor as well and dropping it down to...

    10mm holes within 50mm from top of joist

    I was going to do it every 400, as it's 25mm ply and also on joist tape. Most everything done in this house will be by me, so until I'm dead it should just be me lifting boards, and hopefully by that time my girlfriend will be capable of using an Allen key and taking the boards up before the...

    When in conduit the cables are downrated, and i want to keep them open in cable tray to keep their best rating possible. Yes it is going to drive me insane, but i have 1 month to basically do 2 rooms like this, then we can move our belongings up (bristol to newcastle, so not very fun with pets...

    10mm holes within 50mm from top of joist

    Hi, I would hopefully like to avoid all the comments i know are coming regarding why i would ever WANT to do this, as i know its way overkill, i just want to know if there are reasons why i should not do it, safety and structurally speaking. So i am putting down 25mm plywood in all the...
