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!

The access point doesn’t have to be expensive, as long as it’s not from a costly manufacturer. Ubiquiti has significantly raised their prices, and AVM has always been expensive. TP-Link, for example, is likely much more affordable. The problem is that you can’t seamlessly integrate them into an existing AVM infrastructure. It works, but you won’t benefit from the basic management features.

I am. I just want to understand why I should pay three times as much for an access point, and whether it offers any advantage. So far, I don’t see one.

I don’t see why my access point, including the PoE adapter, was expensive at 80€ (about $85). I wouldn’t have a problem paying double for a better model. AVM’s prices are also in a similar range.

I also recently installed an AVM Repeater 3000 at a friend’s place. It works, but the setup drove me crazy. I’m probably overthinking it. There are many ways to reach the goal.

Well, flexibility is nice, but I would still roughly consider where the number of sockets makes sense for you. I think 15 sockets for 15 m² (160 ft²) in the children’s rooms is excessive. Half that number should be more than enough. In key locations where you might need sockets in 10–15 years due to rearranging furniture, you could have flush-mounted empty boxes installed with just a cable inside. If you really need sockets there later, they can be easily added. For me, sockets behind wardrobes and beds are wasted money because they are paid for but not usable.

You have to decide on the number of sockets. We have about 85 sockets in our 145 m² (1,560 ft²) house, while others have significantly fewer or more.

I hadn’t really considered sockets behind furniture, but I was thinking of sockets for cabinet lighting, charging stations for electric toothbrushes/cordless vacuums, inside cabinets, and so on...

That's exactly what I mean. For rooms of 15m² (160ft²), that’s sufficient.

Regarding power outlets: it makes sense to have some switched outlets here and there and possibly install a two-way switch (for example, by the bed).
Fifteen outlets for a children’s room are excessive. Just think through the devices and everyday life.

I understand that! The children’s rooms are probably overplanned. On the other hand, these are exactly the rooms that will continuously change over the coming years.

I couldn't read everything yet, so I have a question: are there already any plans about which lighting circuits to control separately in the huge open-plan area? And from where you want to control which lamps?
All power outlets are nicely listed, but there's no indication of how many light switches will be installed and where.

Very good question! I'm still not sure if I can/want to afford KNX. That, of course, has a major impact on the switch layout!
