Drilling a c. 15mm hole in a supporting wall 'should' be ok right? I mean, you drill holes for pipes etc. much larger than that in external walls. Will line with conduit.
Just planning out where all the electronics run in the lounge renovation, so it will hopefully be a lot neater than current. I can't figure out a better way of getting a HDMI cable from one side to the other. Concrete floors so can't go under.
