Moving into a new build on the next month or so. We came into the purchase after two prior offers fell through so we saw the build once it was pretty much complete, after the walls/plastering/wiring had been done. This would have been a lot easier had we gotten involved during the wiring/plastering phase.

We want to wall mount the TV as the lounge isn't particularly wide, but I have no idea what to expect. I'll be getting an electrician in anyway to move/install a couple of new sockets but need some input from people who have a much better idea than I to see if my thoughts on layout are too far out.

First plan is to have a cabinet by the window and where all the power/data entry points are in the corner. Run HDMI/Coax and Ethernet inside conduit to where the TV will be mounted on the wall. The conduit will be chased into the wall, cables installed, then plastered and painted.

The wall is dot/dab plasterboard on breeze block, no idea of the depth underneath yet but I'd hazard a guess at around 25-35mm? I will need to get the electrician to double check that next week.

Just have a few questions about layout so I have some idea when I'm talking to the electrician.

  1. Assuming I need the wall chased to install some conduit is the layout shown beneficial (keepng power/data separate)?
  2. Should I grt one channel hased wide enough to accomodate power/data instead?
  3. Plastering over the conduit, what sort of finish can I expect, will it be pretty much perfect or is there much risk of large cracks appearing (depending on quality of the work obv)

I have no experience with this sort of thing so not sure what is feasible or not.

Many thanks.
 
I wouldn't personally bother about splitting the data and the power. Cat6 cable is shielded anyway or just buy some shielded cable.

You say chasing a few times, is it blockwork or studwork?

It shouldn't crack if a proper job is done
 
Personally I'd just do one single channel, can't say I've noticed any issues with mine.

If you're lucky there could be enough of a gap to 'feed the cables' behind the plasterboard (the plasterboard 'glue' usually causes a gap between the panel and block work) although obviously no shielding from drills later down the line.

If you do end up cutting out and plastering, the quality depends on the plasterer but it should look as good as the other walls and cracks shouldn't appear if they do it properly with scrim etc
 
In my experience, data/power are ok together unless it's on an industrial scale.

For a home/tv solution, I can't see it being an issue.
