Dear forum community,

the electrical sub-contractor of my general contractor has now contacted me that he would like to finally discuss the electrical planning on site (at the construction site) with us). I know, normally it is advised to plan this trade from the beginning, but with my general contractor and the sub-contractor it was not possible, they explicitly wanted to do it only at the shell construction stage.

Now I would like to tap into the forum knowledge and your experience for general tips regarding electrical planning.
First, the standard equipment of my general contractor:


Furthermore, it is clear from my side that I need deep flush-mounted boxes for the roller shutters and blinds etc. I plan to equip these with Shellys to enable centralized control (probably later).

Other thoughts we have already considered:
- We do not want spotlights
- When in doubt, rather only 1 double socket and power strip instead of quadruple socket clusters
- We have already purchased square and rectangular LED panels (a total of 7), which serve as basic lighting, but we are completely clueless about special lighting concepts. Indirect lighting is already a known term.
- We cannot obtain professional lighting consultation.
- I am interested in automatic light control with motion/presence detectors. Is this easily retrofit-able with essentially conventional electricity? Is it possible to time-control such a system? For example, in the hallway the light turns on via motion detector, but after 10 pm only dimmed and after midnight not at all? Additionally overridable by a switch?
- My wife likes cold, super bright light; I prefer cozy, dim light. The above-mentioned LED panels are adjustable. Are there alternative options?

From your point of view, what are the most important things to consider? What practical solutions have you implemented apart from the standard and would not want to miss?

Anyone who wants to may also make concrete suggestions. You can find my floor plans here (please ignore the drawn-in furniture):

Thanks and best regards

What I initially miss are the outdoor facilities. Outdoor lighting, lighting of carport/house facade, electricity needed in the garden?

There was a discussion with us about the costs of the larger distribution (BU ended up bearing it) and the installation of CAT cables in protective conduits (ridiculous).
We paid extra for a separate circuit for our home office, motion detectors in the hallway (I quite like it), more LAN cables (every room except the bedroom), preparation for SAT (cable is laid) just in case, dozens of additional sockets, and some more light switches and ceiling outlets.
Also, the oven connection was separately protected and an embedded cable duct for the TV (a gimmick for 70€ that I never want to miss again).

KNX we skipped. If we had a little donkey that spits out money, we certainly would have invested more in smart home.
What I do miss is electric roller shutter control. We went for the classic ones. They have a few advantages (from my point of view), but unfortunately the disadvantage of being ugly in appearance. With today's knowledge, I might change that.

It is a very sparse equipment. There are still 20-40 sockets missing, LAN connections in the ceilings for [Aps], several in the living room, office, etc. Presence detectors can also work conventionally, but with logic it goes more towards [BUS]... You can discuss it on the construction site, but then have the planning given to you and revise the plans calmly. Drive sockets with 5-core wiring. That way they can also be switchable once in a while.

Can only agree with Kati.

Outdoor facilities, terrace (electric awning, lighting...), barbecue area, carport/garage....

What comes to mind:

- Is a simple doorbell enough or should it be something else? If it is to be an intercom system with a camera, then pay attention to the height for the camera. Make sure all cables to that point are laid in a conduit, so that something can be replaced later.

- Preparation for E-charging station + LAN as well or have it done properly right away.

- As Rick already mentioned, don’t forget the access points. Additionally, possibly plan for an outdoor access point for the terrace/garden.

- How should the telecommunications technology be housed in the utility room? Router, patch panel, ... just nailed to the wall or should everything go into a network cabinet? If the network cabinet is to come later, then have the patch panel made with Keystone technology and provide sufficiently long cables. Then you can install the network cabinet yourself later. Please discuss with the electrician how to do the potential equalization for the network cabinet or better have him do it directly. Don’t forget a power outlet in the area of the network cabinet.

I am an avowed friend of keep it simple - KNX, bus systems, smart home, etc. seem unnecessary in a normal single-family house... but the above-mentioned hint from Rick is worth its weight in gold! Definitely take your time!!!

Otherwise, outdoor connections (including LAN), LAN generously (especially in the technical room: heating, ventilation, photovoltaics & storage... everything wants to be networked), shutters/blinds controllable externally is also not a bad idea (we have radio motors), photovoltaics empty conduit.
