Planning electrical systems to be future-proof

I would always have a double socket installed, as it is usually only marginally more expensive. If the electrician wants too much for some reason, then he should use duplex cables and you can upgrade later if needed.

I would plan network sockets for the following areas:
- Printer
- Desks
- Television
- possibly for oven/microwave/washing machine or other kitchen appliances
- Ventilation system
- Garage
- Distribution box
- Terrace (Access Point)
- Ceiling Access Point
- possibly for cameras
- as a precaution, at least 1 duplex in the attic.

As a rule, I would generally always have double sockets installed. There are already prefabricated Cat7 duplex cables that should also make it easier for the electrician to lay them. I would possibly plan it like this:

UG
Double socket in the garage. Could be interesting for future wall boxes if needed.
Double socket in the office (at the edge where the desk will presumably stand)
Single socket in the hallway for a door indoor station
Cable outlet at the house entrance for a door outdoor station
I am assuming that you will accommodate the cables and the server cabinet in the technical room. Then, in my opinion, you don’t need an extra connection there since the switch is right nearby in the same room.
That makes a total of five LAN connections plus an outlet for the door outdoor station and one access point = 7 installation cables



EG
Double socket in the utility room
Double socket at the TV spot
Single socket in the hallway for a door indoor station
That makes a total of five LAN connections plus two APs = 7 installation cables
Notes: Outside, I wouldn’t necessarily have a network socket installed next to the access point. That might only be interesting for a camera, if you’re interested in something like that. Otherwise, consider again if there might be an alternative TV spot.



OG
Double socket in Child 1
Double socket in Child 2
Double socket in the bedroom
Single socket in the hallway for a door indoor station
That makes a total of seven LAN connections plus one access point = 8 installation cables
Note: If you’re not sure about the furnishing in the children’s rooms, one could additionally have a double socket installed on the opposite walls or one single socket each.



That would bring you to a total of 22 installation cables. They fit nicely on a 24-port switch. Please note the following: besides the pure LAN connections, some components still need to be connected directly to the switch. For me, for example, the FritzBox, a NAS, and a Doorbird I/O controller are connected directly to the switch. After all, a FritzBox still offers a few connections.

I would then buy the components for the network cabinet myself and ask the electrician to properly terminate the installation cables at the patch panel in the network cabinet. It is also important that you have keystones installed there, which terminate the installation cables at the patch panel. These can be removed later or rearranged in order if necessary.

For example, mine looks like this:

Here you can see how the yellow installation cables arrive from the left and are then introduced in bundles into the network cabinet from the back at the top.


Here you can see the network cabinet I generously chose to also have space for the NAS and the FritzBox.


Here again in close-up the assignment of the patch panel. We were lucky that our electrician worked very neatly here and labeled the fields nicely. From the patch panel, several patch cables then run via an upper and lower brush strip to the switch. But of course, that’s just cosmetic.

I would generally always have double sockets installed. There are already prefabricated Cat7 duplex cables that should also make it easy for the electrician to install them.

I have written that on the construction planning list - how much is a double socket compared to a single socket? And if it is only slightly more expensive like with you, we will take the double sockets.

Ground floor
Double socket in the utility room
Double socket at the TV area
Single socket in the hallway for a door indoor station
That makes a total of five LAN connections plus two APs = 7 installation cables
Notes: outside I wouldn't necessarily have a network socket installed next to the access point. It could only be interesting for a camera, if you’re interested in that kind of thing. Otherwise, think again whether there could be an alternative TV position.

I forgot the door indoor station, thanks!
I find the TV area really difficult. The partition wall will be exposed concrete and should look accordingly clean. The TV will be mounted on the wall. Therefore, I think it makes sense to plan power, satellite, and network behind the TV and below at lowboard height power and network again.
What do you think about that?

Regarding the two outdoor network sockets: I had one planned for the awning (app control?) and one for the outdoor access point?

There will be another TV spot in the utility room.

Note: If you are not sure about the furnishing in the children's rooms, you could also have an additional double socket installed on the opposite walls or one single socket each.

We have discussed the furnishing in the children's rooms several times and *we* are clear about it. But whether the children will see it similarly in 10-15 years?

I would then buy the components for the network cabinet myself and ask the electrician to properly terminate the installation cables at the patch panel in the network cabinet. It is also important that you have keystones installed there that terminate the installation cable at the patch panel. These can be removed later or rearranged in order if necessary.

For example, mine looks like this:

Once again finally: Many thanks for the detailed explanation and the photos!

I advise you to familiarize yourself with the topic "Switch, Patchpanel, Router, IP address assignment." It's not rocket science. If you let everything run on automatic address assignment, you don't have to worry about network protocols, etc. But if you have the electrician do everything, you will have to call him for every tiny "problem." That costs money, time, and nerves. Nice cabling like in the photos above looks great but doesn't help at all if you don't know which cables have which functions.

I would have the electrician do the cabling and the consolidation in the network cabinet and then take care of the prior planning of the components and the subsequent setup/installation of the network on the PC myself. Small spoiler: I will need you again to approve the components. :P

I would also install a network socket in the basement room [Garderobe/Abstell], at least a simple socket. If it is ever going to become a hobby room or sports room, you will be glad.
