Dear forum,

we are currently planning the construction of our single-family house. Last week, I created an initial draft for the lighting and electrical installation, which I would like to share here for discussion.
Do you think I should reduce the number of recessed ceiling lights? Are the power outlets sufficient? I look forward to your comments!

Yes, the only question is what you and he each understand by that term.

That’s exactly what I meant,
there is a wide range between 100% of today's possibilities and none at all, which might already be sufficient for the OP

According to our electrical installer, it can be upgraded to smart home at any time, depending on budget or interest.
This also applies if you only install standard equipment. It will just be more complicated/more expensive/not as neat.

Which software did you use to mark the spotlights, ceiling outlets, etc., on the plans?

I just did it by hand on the iPad using GoodNotes.

Hello Hendrik,

I recently completed my build and also decided to go with KNX.
Below is a cost breakdown of our entire electrical installation, which might help give you a rough idea (state: Lower Saxony, about 170 sqm (1829 sq ft)), although in the end it really depends on individual needs.

KNX:
- Planning: €775 (performed by system integrator)
- Control cabinet construction: €2,600 (performed by system integrator)
- Control cabinet materials: €3,500 (terminal blocks, actuators, etc.)
- Programming: €1,800 (by system integrator; definitely possible and recommended to do yourself, but we simply didn’t have the time to dive into it)
- Sensors (7 push buttons, weather station, 14 reed contacts, 8 presence detectors, 2 motion sensors): €2,400

Cabling & distribution board:
- Cabling for LAN/duplex LAN (total of 22 LAN ports in the house), satellite (6 locations), sockets (approx. 90), lighting points (approx. 35), smoke detectors (7), and of course bus cables installed extensively (lots of spare capacity), plus all other necessary cables (e.g., audio cabling), including cable materials, installing boxes, and distribution board: €23,000 (performed by electrician)
- Materials for the “visible” installations (sockets, smoke detectors, etc.) were sourced by us: €1,100
- Final connection of all boxes, lighting points, etc. done by ourselves

That adds up to roughly €35k. Then there were additional elements like the door station (video doorbell), access points, a 19-inch rack with corresponding components, satellite dish, all the lighting, and other items, which brought the total to just under €40k for the entire electrical installation. And by that, I mean the full setup.

As mentioned, there’s probably some room to save here and there, and I might have missed a few items included in the prices, but that’s roughly what I can report from our build regarding KNX.
