Running Cables down a corner

[Spinny]

Concerned about the size of my TV conduit, so contemplating running some cables down from the ceiling in this corner - maybe speaker cables or a network cable.

 

There is a movement joint in the wall there - I guess I am not supposed to run any cables in the edge of the joint ?

(It hasn't moved in the 2.5 years it has been up)

 

Might fit a wall cupboard or a shelf into the corner - not sure what the best position would be really for cables - tight to the corner ? - or middle of the short recess wall ?

 

Think I need to run the following 15m to the TV...

 

1 off directional HDMI optical cable

2 off Cat 6 network cable (one as a spare)

3 off speaker cables (right, left and centre channel)

Coax aerial cable 

Digital optical audio cable

Samsung OneConnect optical cable ? (looks like the ends don't come off, so would have to go through the conduit on its own first.)

 

??

I'd be thinking of either  the cupboard or a boarded in service void, then run the cable without conduit in this area

From that picture I think I’d lean towards boxing it out 25mm or 50mm with roof battens to create a void on the short edge of that corner.

There is a bit about installing data cables here.

As far as I know they do not have to be in a safe zone, though newer PoE may be different.

@crispy_wafer Yes thinking along those lines.

The walls are going to be wet plastered and NOT dot & dab. Wondering if I could put some shallow trunking down the narrow recess wall and then get the plasterer to thicken up the plaster on that recess wall.

 

(Annoyingly there is a steel beam above (and a steel column inside the wall) - will have to run the cables around the steel.
