ᐅ Lighting Design for a Single-Family Home with KNX Automation

Hi everyone,

we are currently finalizing the electrical planning, including the placement of outlets in the ceiling. What do you think about this, and where do you see potential for improvement?

Legend:
- Green: Spots in halogen boxes
- Red: Simple light points (surface-mounted, e.g., spotlights or fixtures)
- Yellow: Spotlights in drywall elements (so quantity and position are still flexible)
- Green stripes: Drywall elements for cove lighting
- Yellow stripes: LED strips

I have framed and partially numbered the control groups.

For the children’s rooms and the office, I am considering wiring with 5x1.5 mm² (about 14 AWG) cables to allow for a flexible lighting setup later on, for example through suspended ceilings. Operation will be via KNX.

I’m leaving out the planning for the basement and entrance area here, as it’s standard. The floor plans do not exactly match the current construction plans, so please don’t judge dimensions or similar—the architect will place the outlets correctly.

Best regards

I would say: back to the drawing board and start over.

Once again, there are far too many spotlights/recessed lights, especially the excessive number of holes in the bathroom. What is the real purpose of all this? In the age of LEDs, you can achieve what you have in mind with significantly fewer individual light sources, and much more evenly distributed light. If you plan three lighting zones in the bathroom, simply use three stylish, flush-mounted ceiling panels, either round or square. These will provide more than enough light, possibly even tunable white (TW) versions—which I would consider for any new build if it hasn’t been done already.

Eight light fixtures in a 20sqm (215 sq ft) hallway is again at the level of a medical practice.

Otherwise, the basic concept with multiple lighting groups isn’t bad. However, I would suggest considering wall lights here and there, as well as backlighting in the media areas. Also think about terrace and garden lighting.

For the kitchen, it’s not quite clear whether countertop lighting or similar is planned.

Yes, reduce the number of recessed lights, it's completely excessive. For example, one light above the toilet and shower area should be enough, maybe two in the shower.
