ᐅ Planning Electrical Systems for Future-Proofing

Hello everyone,

In about three weeks, we are supposed to finalize our electrical planning on site. Unfortunately, our electrician is somewhat old-fashioned, which makes it difficult for me to collaboratively plan a future-proof electrical setup with him. Therefore, I am currently educating myself to ensure that the networking in our single-family home is fundamentally future-proof.

Basically, it’s about the LAN network... LAN wall outlets are relatively expensive, so proper planning is even more important.

About us:

- Mid to late 20s – couple without children. Planning for 2 children in the near future.
- Single-family house with a usable basement, 2 full floors, and fully equipped with concrete ceilings
- Utility room in the basement with air-to-water heat pump, ventilation system, photovoltaic system
- The router is planned to be located in the office on the ground floor
- The upper floor includes bathroom / bedroom / 2 children’s rooms
- No satellite dish or cable TV — we will use Internet TV exclusively!

Now, I am struggling to network our single-family home sensibly but as cost-effectively as possible.

I have the following questions:

1. Slightly off-topic: In the living room, I would like to have an in-wall conduit installed on the TV wall (the TV will be wall-mounted) so that no cables are visible. Is this sensible and affordable? I will get exact prices from my electrician if this makes sense at all. Would it also make sense to install power outlets at TV height? How do you plan the connections on your media wall reasonably? What should be considered?

Since we plan to use a Magenta TV box and thus IP-TV, a total of four LAN ports in the living room area would presumably be useful, right?

2. How many LAN outlets and especially where should LAN outlets be installed? Mainly: which cable? Is CAT6 sufficient?
→ Such a double LAN outlet certainly costs close to €200, so planning must be really sensible.
Is it really necessary to install 2 double LAN outlets in each children’s room? I always wonder: what is actually going to be plugged in there?
One port for the TV and one port for a multimedia device should be enough, right? So four connections would probably be overkill, correct?

The fact is: It will certainly take years or decades before our children actually use these outlets... Who knows what changes might happen by then? Therefore, could we not cost-effectively use empty conduits (empty pipes) instead?

Is it also possible to “branch off” from an existing double outlet afterward to add more ports for the room? What should be considered here? Or should we consider having an empty conduit prepared in another spot in the room so that a socket can be installed later?

3. How do you solve the “router problem”? Should the one router be placed in the office (ground floor) with LAN outlets in the existing bedrooms upstairs to ensure a stable LAN connection? Or is a router upstairs absolutely necessary?

4. How important are LAN outlets in the utility room? Should the router possibly even be located in the utility room? Because of the concrete ceiling between basement and ground floor, a second router would almost certainly be needed. How should this situation be handled with a basement?

5. What do you think about installing empty conduits for CAT cables in the kitchen / hallway etc. to enable later retrofitting? Is this relatively affordable in new builds?

I would appreciate any feedback so we can make the best possible plans 🙂

Conventional electrical systems are more like a 10-20 year old diesel engine than a beautiful vintage car :p
I’d rather compare it to a horse-drawn carriage. That fits conventional systems perfectly. A 10-20 year old diesel usually has more automation than you might expect.

Although I would still prefer a 10-year-old diesel over modern cars that control you at every turn. It’s somewhat the same with home automation: there are some things I can imagine automating, and others not.
Here you clearly show the difference between the forced automation systems from manufacturers (closed systems like Somfy, Rademacher, Bosch, etc.) and the freely configurable, open systems such as KNX, Z-Wave, Zigbee, and so on.

With the first type, it’s take it or leave it. If you want the (manufacturer-specific) home automation system, you have to accept the restrictions and shortcomings of the system. You’ll wait for updates that never come and miss important functions or have to adapt yourself to the limitations.

With the latter, it’s different: you can model and change everything exactly as you want, not as dictated by some manufacturer.

Before selecting the power outlets, make sure that they can be installed flush and completely aligned with the wall in the new building, unlike older systems where they often protrude several centimeters (inches) and look unsightly.

What do you mean by that, and how does it relate to future-proofing?

However, this requires special recessed mounting boxes and comes with a higher cost. It looks nice, but on my priority list, it would be well behind smart home features.

Several centimeters, you hopefully don’t mean protruding beyond the plaster?
The 1cm (0.4 inch) raised edge is meant to help locate the switch by touch in the dark.

The 1cm (0.4 inches) buildup is to allow tactile positioning of the switch in the dark

Try searching for Gira E2 flush mount. The design then only protrudes 3.4mm (0.13 inches) from the wall. However, special flush mounting boxes are required.
