Electrical planning - Is something missing?

To those who have installed empty conduits: Which type and diameter did you install?

We have a prefab house with ready-planked walls and empty conduits reaching down to the floor. He did mount deep boxes, but only 20mm conduits, though at least the really good ones with membrane. 25mm conduits don’t fit particularly well in the airtight boxes, so that’s understandable. For this reason, we mostly continued with 20mm conduits to ensure a flawless connection, but where sensible also used 25mm, 40mm, and 50mm for larger cable ducts, e.g., between the basement and the technical room. Through the 50mm ones, however, you can also run 10-12 NYM cables or up to 15 CAT cables. What really isn’t fun is pulling cables through already firmly seated conduits, so cut first, fill with cables, and then lay, that works best. Otherwise, lubricant, insulation tape, pulling aid if necessary, and above all: good preparation. To get, for example, 3 NYM3 and 6 NYM5 cables into a 50mm conduit, I first sorted the cables for half an hour and tied a bundle so that the cables don’t cross. Anyone who takes this trouble will be rewarded by being able to simply push the bundle through. One more thing about the spots: I think the ones in the kitchen won’t work particularly well, if I imagine it like that. Is the oven at the bottom on the right outer wall? If yes, you’ll probably produce shadows on your roast with the spot, e.g., when you take it out, just like with the others, except the one over the sink. If spots at all, then directly over the workstations, then it works. We also installed spots in the kitchen and hallway in an open wooden beam ceiling, and with the positioning you can almost completely eliminate shadows. But you need quite a few for that.

Proverb WLAN: due to today's new building floor slabs, no WLAN signal gets through anymore. Directly above our utility room, there is no! signal from the current FritzBox in the bathroom (no WLAN network is found). It is strongly recommended to plan an access point on every floor. (or a LAN connection to later connect your own device to the LAN connection).

If you use SAT, double sockets actually make sense almost everywhere (simply because each receiver gets its own connection), and then 12 sockets are not particularly many. We have only installed 5x DVB-C (cable) and 0 SAT.

12 cans = usually 12 rooms. I don't think that's few...

I don't understand your reasoning about the double cans.

Ah, prefabricated house, that of course explains the laying of electrical cables in empty conduits. We are building solid (maybe I should have mentioned that, sorry) with Poroton walls and concrete ceilings. Only the SAT and network cables are to go into the empty conduits, electricity will be laid in the traditional way under plaster. The tip that the empty conduits must fit the boxes is already helpful, thanks, I hadn’t had that on my radar!

Yep, you’re right, we already have that problem in the current house and it won’t get any better in the new building with a 22 cm concrete ceiling with lots of steel in it. You won’t get far with a Fritzbox there. Switching to the country code China doesn’t help much either...

I understood about the stairs, but 1 spot in the ceiling in the stair area is definitely too few. We have 3x20W over the stairs and 3x20W in the upper hallway. Basic lighting (stairs, bathroom) (8x1W) is on from 6 p.m. to 7 a.m., so I don't have to turn on the light at night when I go to the bathroom, and the stair light is only turned on when you really need a lot of light.

We used 25mm pipes for CAT7 duplex, but pulled the cable directly into the pipe.

P.S. I would install the network sockets correctly in the children's room right away, otherwise you will regret it later.

We also have the bathroom in a T-shape. What do you want with a 2m long shower? You still need a glass door. We have a 1.60m shower and 1.6m for the toilet; no one sees me.
For the bathroom, I recommend 2 exhaust vents, one in the room and one above the toilet.

@ Sebastian,
Payday means the cans with two connectors to connect a twin receiver.

Best regards,
