Hello everyone,

Here are some basic details about the house: single-family home (basement, ground floor, and upper floor), approximately 180 sqm (1,940 sq ft), solid construction with brick.

We had the architect exclude the heating/plumbing (which I can handle myself) and electrical work. Recently, we had an appointment with a friend who will do the electrical installation for us. What do you think about the costs?

- Downlights LTS
Planning downlights, ceiling plan, recessed fixtures: about €5,000 - 6,000

- Step lighting from basement to upper floor: about €1,500

- LS switch system by Jung: about €1,500

- Bus system (KNX/EIB): about €6,000 + Jung control panel €1,500

- Outdoor lighting with dusk sensor control: about €400

- Indoor intercom system by Jung: about €500

He said that including all materials and labor, the total would be around €28,000.

Do you think these costs are reasonable?
Are there alternatives, especially for the downlights?
Are downlights even practical?

Thank you very much.

Best regards,
Benjamin

The price seems reasonable, although the question is how much more expensive your general contractor (GC) would be. You do have some additional features, but it still appears to be on the lower end of the price range (exterior lighting, intercom system, etc.). The KNX system also seems quite affordable to me. If you decide to go with it, make sure it is fully comprehensive (lighting, power outlets, roller shutters, a proper control concept, motion detectors).

Regarding downlights, I’m a bit conflicted. I find them quite good in hallways, especially if they can be combined or alternated with indirect lighting. I would like to have them in the bathroom (planned for the future), but I find them less cozy in living rooms, where you need to pay close attention to the light output. Achieving uniform illumination requires relatively many spots (LEDs have narrower beam angles). This can result in very bright lighting, so I would at least combine the setup with a dimmer.

Aesthetically, I don’t like surface-mounted downlights, but that’s a matter of personal taste.
