We have a new build that will be finished soon.
Unfortunately, the developer did not offer an in-wall conduit.
Can we install it ourselves afterwards?
Our wall consists of 15cm (6 inches) sand-lime brick plus insulation.
Our TV wall is the exterior wall.
If yes, what would you recommend?
How wide and deep should it be?
1 power cable, 4 HDMI cables, and 1 USB cable need to fit inside the conduit.

Bausparfuchs12 Feb 2023 20:31A 15 cm (6 inch) wall is quite thin, especially as an exterior wall. But that is not the topic here.
Just lay your cables side by side. Use a grinder or planer to cut a channel 5 cm (2 inches) wide and 1 cm (0.4 inch) deep into the sand-lime brick. Then fix the cables in the wall with hot glue. The plasterer will handle the rest.

Gooosee15912 Feb 2023 20:43The total wall thickness is 34cm (13 inches).
15cm (6 inches) sand-lime brick, 19cm (7.5 inches) insulation boards.
I have already found a multimedia channel about 6cm (2.5 inches) deep.
My question is, can I later remove 6cm (2.5 inches) from the wall? Or is that too much?
@kati1337 yes, that's what I mean.
How many cables fit inside for you?
@Bausparfuchs gluing is not an option.
The cables must of course remain replaceable.
Different cables need to pass through it.

xMisterDx12 Feb 2023 22:51You don’t need a specialist for this. Just buy a standard enclosed cable duct, drill two holes in the lid and the wall, and install it.
However, for your cables, you definitely need a sufficient width and depth, or rather height, of the duct.
Whether you can just cut an 8cm (3 inches) wide and 4cm (1.5 inches) deep channel in a 15cm (6 inches) load-bearing exterior wall... no idea. Especially since the wall will be further weakened in that area by the holes for the TV mount.
At 11cm (4.3 inches), it’s no longer a load-bearing wall.

According to DIN standards, a slot in the wall should not exceed a certain size. Please research yourself to find the exact maximum dimensions.
We simply used a flat duct from the kitchen department (6cm deep, 10cm wide) and chiseled out the load-bearing interior wall made of sand-lime brick (24cm (9.5 inches) thick) enough so that the duct could be plastered in. So far, the wall is still standing and even supports the TV. 🙂 It was quite a hassle to chisel it out afterwards; it would have been better to do it while building the wall.
Alternatively, you could install a narrow drywall partition in front of the wall—using a 50mm (2-inch) metal stud, simply covered with drywall. Although this reduces the room space by 6-7cm (about 2.5 inches), it is safer from a structural point of view.
Vertical slots and recesses –
For wall thicknesses of 11.5cm (4.5 inches) and 17.5cm (7 inches) – maximum width 10cm (4 inches) – from 11.5cm (4.5 inches) openings – generally only 1cm (0.4 inch) deep.
For 24cm (9.5 inches) wall thickness – maximum width 15cm (6 inches) – from 11.5cm (4.5 inches) openings – generally only up to 3cm (1.2 inches) deep.
