Planning sockets and burn sites

If children are already there or planned, then plan a double network socket in their room. In an office, rather 2 (I only have one and I am missing the second).

I am now reading 48 sockets in the entire house. I would at least double that. You can never have enough.

Example living room. You have 10 sockets and one TV socket (Sat?). What is usually connected? Double satellite receiver ==> already missing one connection. Smart TV with network connection ==> you can't connect it at all, at most via WLAN (which I don't think much of in new buildings). TV/receiver/Blu-ray player/soundbar or amplifier/Playstation ==> 6 sockets used up, hi-fi system CD player or similar, floor lamp, telephone (I would only connect that via network connections anyway), small lamp on sideboard or windowsill, Alexa, electronic photo frame, phone charger...

Example bedroom. You have 6 sockets and one TV socket. Waterbed + lamp on the bedside table + each one a charging cable for the phone and/or alarm clock and the six sockets, distributed throughout the room, are gone. What about a nice floor lamp for cozy lighting? Or the lighting for the wardrobe? Or or or.

For example, on a real 70 sqm living space (without balcony) I have almost one socket per sqm. In a normal single-family house, 100 sockets are not a big problem. Unless you want to work with multiple socket strips.

Otherwise, others have already written enough about network, wall lamps, reveal boxes, etc.

In the light, it occurs to me that switchable sockets for floor lamps could be made.

In the outdoor area, you need light in front of the front door and on the terrace. Doorbell or video/intercom system at the front door?

On the subject of telecommunications.
What kind of internet connection do you get? Fiber optic, cable, VDSL? Usually, every type of connection terminates in the utility room. Ideally, the (multi-function) router is also located there. After the router comes a switch to connect the router to all network cables. The network cables go to the desired rooms. I personally would put a double socket in every room. Where one double socket is already too few at the beginning, make two right away. I would provide one WLAN access point per floor. It is best to install this on the ceiling. No power is needed there, as these devices can be powered via POE (power over Ethernet cables). In your utility room, either one POE injector per access point or, if there are more POE devices, a POE switch will be installed. Rooms that may become a hobby room or garage in the future, I would connect with empty conduits to be able to lay network cables there later. Generally worth mentioning: network cables are replaceable when laid in empty conduits! If you have a DECT phone, you can usually register it directly on the router. The range of DECT is higher than WLAN and is therefore sufficient for the whole house. Otherwise, there is, for example, a Gigaset Go Box that you can connect to a network socket somewhere in the house. You can also register your DECT devices there. If you still have an old analog phone, you can also repurpose the network cabling. Otherwise, there are IP phones today that connect to the network.

Regarding TV, one can argue whether to still do wiring nowadays or to go directly for IPTV. Everyone has their preferences, but traditional TV as we know it is rather a model being phased out.

The sockets outdoors are often made switchable. In my opinion, you don’t really need that. These days, burglars come with battery-powered tools. And I didn’t see any point in the house where a switch would have made sense. If any Christmas lights go outside someday, there is a wireless switch for that. For the planning, you should think about where which furniture will be placed. In the bedroom, I find it practical if the sockets at the bedside table are above the bedside table, so reachable, and not just above the floor. You will get a kitchen plan when you buy the kitchen. Consider how you walk through the house and which lights you want to control from where.

Google RAL-RG 678, it roughly states the minimum equipment.
Go through your current apartment. Where is a socket missing, where does it fit, etc.
Then take your house floor plan, e.g. kitchen, where should devices be fixed, coffee machine, Thermomix and so on.
Tip from our expert and add some more everywhere from double to triple sockets etc.

Light switches similarly. Light should go off next to the bed, next to the doors and maybe also next to the sofa. Go through the process. Possibly motion detectors in the hallway. When your hands are full it will automatically get light.

We have 3 outdoor sockets on each side of the house, more on the terrace. Christmas lights, tools, battery charger, etc.
All under the motto better to have than to need.

Sat if available for every device or potential device
LAN in the living room, children's room, office, bedroom

- Thanks for the detailed description!
You are obviously the expert, so I am turning to you with my question:
In our planned two-story house, which will be inhabited by two of us, I want to integrate a sufficient standard WLAN setup, nothing more! Not too much, not too little.
My "plan" is to have the router in the utility room, next to it the switch. From there I will run one LAN cable to each TV connection and install one LAN socket at each TV location.
Furthermore, I will lay a cable to the upper floor to the planned access point (e.g., on the ceiling) that supplies the upper floor with WLAN. To be absolutely sure, I will also lay one LAN cable in the upper floor to the other corner and one in the ground floor to the other corner of the floor.
That way, I am sufficiently equipped with WiFi, right?
Our laptops no longer have LAN ports, and even the printer runs via WLAN. The internet speed will be about 100 Mbps there; visitors also exclusively use WiFi.
I would like to avoid a satellite dish; does IPTV deliver the same thing, meaning will I get the same channels (more or less) as via satellite?
I will do telephony via DECT or directly on the router, or I will lay a cable/empty conduit to the desired location.
Thanks in advance....
