Dear forum community,
The electrical subcontractor from my general contractor has now reached out, saying he would like to finally discuss the electrical planning on site (at the construction site). I know that normally it is recommended to plan this trade from the very beginning, but that was not possible with my general contractor and the subcontractor; they explicitly wanted to do it only once the shell is finished.
Now, I would like to tap into the forum’s knowledge and your experience for general tips regarding electrical planning.
First, the standard equipment from my general contractor:
[QUOTE=Scope of work from the general contractor]
You will receive the complete electrical installation according to VDE standards including
meter cabinet, distribution panel, equipotential bonding, circuit breakers, and residual-current devices in the building.
Standard switch program and sockets (Elso, Berker, Jung or Busch/Jaeger) — white. Connected load of the
house: 14.5 kW. Battery-powered smoke detectors will be installed in all required rooms.
For underfloor heating, all rooms will have room temperature sensors. CAT 7 network cabling consisting
of one RJ45 double socket in the living and bedrooms and a patch panel in the utility room.
Hallway
1 lighting point
1 two-way switch
1 double socket outlet
1 doorbell system with chime in the hallway
1 external lighting point
House connection room
1 lighting point
1 off switch
1 double socket outlet
1 connection for outdoor temperature sensor
1 socket for the washing machine
Kitchen
1 lighting point
1 off switch
4 double socket outlets
1 socket for the refrigerator
1 socket for the dishwasher
1 cooker connection outlet
1 socket for the extractor hood
Living room
2 lighting points
2 two-way switches
4 double socket outlets
1 antenna empty conduit
1 telephone empty conduit
1 lighting point for the terrace
Guest WC
1 lighting point
1 off switch
1 double socket outlet
Each additional room
1 lighting point
1 off switch
3 double socket outlets
Bathroom
2 lighting points
2 off switches
4 socket outlets
[/QUOTE]
Furthermore, it is clear from my side that I need deep flush-mounted boxes for the blinds and shutters. I plan to equip these with Shellys for centralized control (probably at a later stage).
Other thoughts we have already considered:
- We do not want spotlights
- If in doubt, rather one double socket outlet and a power strip than banks of quadruple outlets
- We have already purchased square and rectangular LED panels (a total of 7) which will provide basic lighting, but we have absolutely no idea about specialized lighting concepts. Indirect lighting is already a familiar term.
- We cannot afford professional lighting consultation.
- I am interested in automatic lighting control with motion/presence sensors. Is this easily retrofit-able in a conventional electrical installation? Can such systems be time-controlled? For example, in the hallway, the light turns on via motion sensor, but after 10 p.m. (22:00) only dimmed and after midnight (0:00) not at all? Additionally, overridable by a switch?
- My wife likes cold, very bright light, while I prefer cozy, warm light. The aforementioned LED panels are adjustable. Are there alternative options for this?
From your perspective, what are the most important things to consider? What practical solutions have you implemented beyond the standard equipment that you would not want to miss?
Anyone is welcome to make concrete proposals. My floor plans can be found here (please ignore the furniture shown):

Hi @all,
Thanks for all the great suggestions.
I have a few more questions:
I planned three KG conduit pipes from the utility room to the outside: one for the doorbell and power to the front, one for power to the carport/parking space, and one for cables to the front.
Is that enough for now? Is there an advantage to pulling the cables in right away?
I have two outdoor light fixtures as standard: one on the front door side, one on the terrace side.
Apart from the parking space, I can’t really think of anywhere else I’d need outdoor lighting.
Outdoor sockets: is one per side of the house enough?
Access points: is one per floor sufficient?
All fixed devices would be connected via LAN.
Does the controlled ventilation system and heat pump need to be connected by the electrician using fixed CAT connections? Can’t I just run a cable myself and attach it to the ceiling? It’s a (fairly small) room after all.
A simple doorbell would be enough for me, but we’re planning a conduit pipe to the front anyway (see above).
If I equip the logic-controlled switches with Shelleys, is that sufficient?
The conduit for photovoltaics is already planned. Although the electrician wanted to install a cable during the initial consultation. How should I argue here and what kind of conduit is needed? From another recent thread discussing this, I didn’t really get any clearer information; multiple conduits were suddenly mentioned.
Are there any technical or other reasons beyond aesthetics and cable clutter that speak in favor of fixed multi-socket outlets instead of power strips?
How many ceiling light outlets do you have in the different room types?
Sorry for some of the very beginner-level questions.

Otherwise, the actual planning always takes place during the shell construction phase.Tolentino schrieb:

Dimmer in the bathroom
Dimmer in the dining area
One or two sockets operated by light switches is always useful.
In the utility room, we have quite a high demand: router, refrigerator, several chargers...
Today, I would plan USB charging outlets in the kitchen, on the sofa, and in the bedroom.

When my wife is in the house. 🙄
No kidding.?Are we supposed to review 77 pages now to see how you will build it?
I don’t understand.
The floor plan, in terms of the walls, is finalized and linked above. However, my wife can’t decide exactly how the furnishing will look until there is at least screed and interior plaster in the house.
I made a draft for the open-plan living area, which will probably reflect the actual furnishing more than the architect’s plans. But even in the hallway, with cabinets and shelves, my better half absolutely doesn’t want to make a final decision.
Here is the link to the open-plan living area draft (outdated room depth, 25cm (10 inches) will be added):
